The next decade will redefine what it means to “know where you are.”

GPS changed the world – but it was never meant to carry it alone. As the global landscape evolves, reliance on a single navigation source has become a weakness. The future of navigation lies in fusion – combining multiple constellations (GPS, Galileo, GLONASS, BeiDou) with inertial sensors, radar, visual odometry, and AI-driven correction algorithms.

At infiniDome, we’re already building toward that future. Our R&D teams are developing next-generation protection systems designed not only to defend satellite navigation but to augment it. By fusing data from multiple sources, future platforms will be able to maintain accurate, trusted positioning even when GNSS is unavailable or compromised.

This evolution isn’t science fiction – it’s the next logical step in autonomy. Drones, vehicles, and defense systems will soon rely on adaptive navigation intelligence that constantly verifies, cross-checks, and corrects its own data. GNSS will remain a cornerstone, but resiliency will be built into the core.

Our mission is to make sure every platform, military or commercial, has that resilience from the start. Because the future of navigation won’t just be about precision; it will be about confidence.

In the era of electronic warfare, protecting navigation equals protecting sovereignty.

For decades, nations invested heavily in air defense, cybersecurity, and communication security yet one layer remained underestimated: navigation resiliency. As GNSS interference grows more sophisticated, it’s clear that positioning and timing have become pillars of national security.

When jamming disrupts GPS-guided convoys, precision strikes, or logistics coordination, the entire chain of command is affected. Civil sectors are no safer: air traffic, rail synchronization, and financial systems all rely on stable timing from GNSS.

This is why governments and defense organizations across the globe, from NATO to the EU Space Program, are prioritizing PNT (Positioning, Navigation & Timing) protection. And this is where infiniDome delivers unique value. Our modular, scalable systems can be integrated into existing platforms or infrastructure, providing an additional, easily deployable layer of protection that detects, analyzes, and suppresses interference in real time.

We believe that national resiliency must include navigation resiliency. It’s not just about knowing where you are; it’s about ensuring your nation can operate when others can’t.

Our technology empowers governments and integrators to close that gap today, securing not only missions but also economies that depend on uninterrupted GNSS.

From autonomous vessels to carbon-capture missions, the ocean has become the next front for GPS interference.

The open sea was once considered the most stable navigation environment. But in the last few years, it has turned into one of the most unpredictable. Ships across the Black Sea, Eastern Mediterranean, and even the Red Sea have reported widespread GNSS disruptions – sometimes lasting hours, sometimes days. These interferences don’t just threaten commercial routes; they endanger safety, data integrity, and even environmental missions.

At infiniDome, we’ve seen how maritime and scientific operations now face the same interference challenges as military systems. In 2024, our technology played a crucial role in the Rewind’s marine carbon-removal experiment, ensuring that data-collection vessels maintained precise positioning and communication despite heavy RF activity near coastal zones.

Maritime operators are starting to recognize that GNSS protection isn’t a defense-only issue. Offshore energy platforms, autonomous boats, and ocean-mapping systems all depend on continuous navigation and timing. A few seconds of jamming can lead to lost data, operational drift, or even physical danger.

Our systems, such as SunStone, are compact enough to integrate into small vessels yet powerful enough to defend against high-power jammers. They don’t just maintain positioning; they ensure mission continuity, even when the ocean turns silent above the satellites.

As maritime industries move toward autonomy, resilient navigation is becoming as vital as radar.

What happens when your system is tested under real interference – not in theory, but in combat.

In modern warfare, GNSS interference is no longer an exception – it’s expected. In conflict zones, signal degradation is part of the daily reality. The question is not if your navigation will be jammed, it’s when.

For infiniDome, that’s exactly where our technology proves its worth. Our systems have been deployed in active combat zones, integrated into UAVs and tactical drones supporting military units under electronic attack. In these environments, GPS signals are constantly being jammed or spoofed by high-power transmitters designed to disable unmanned systems.

The results speak for themselves: platforms protected by infiniDome continued to operate, transmit, and complete missions when unprotected systems failed. That’s what we mean when we say “battle-proven.”

These lessons from the field shape every product we build. We don’t just simulate jamming – we fight it. And every success story from the frontlines helps us design better protection for the future, across both defense and commercial domains.

Because in today’s world, navigation is not a convenience – it’s survival.

GNSS protection isn’t just about blocking interference; it’s about enabling continuity.

When a drone loses GPS, it loses more than its location. It loses orientation, timing, and control. That’s why infiniDome’s engineers design every product around a single principle: preserve the mission, not just the signal.

At the heart of our systems lies a technology known as adaptive null-steering – a spatial filtering method that allows our modules to “hear” and isolate the real satellite signals while suppressing jamming sources in real time. Unlike passive filters, our approach actively reacts to the interference source, steering it out of the receiver’s field of view within microseconds.

 Our systems – like Aura, Resilient Navigation system, and SunStone – provide unmatched reliability without compromising weight, power, or size. This makes them ideal for platforms ranging from small tactical drones to large autonomous ground vehicles.

But the technology goes deeper. Our architecture doesn’t just protect; it detects and monitors interference events, giving operators visibility into the electromagnetic environment in real time. That insight allows them to plan better, respond faster, and maintain trust in their navigation systems even in hostile conditions.

At infiniDome, innovation means simplicity in integration and reliability in the field.

Because in GNSS protection, the best success stories are the ones where the interference went unnoticed – and the mission continued flawlessly.

As India becomes a global UAV powerhouse, the need for GNSS protection takes center stage.

India’s UAV market is growing faster than almost anywhere else in the world. Fueled by ambitious national programs like Make in India and a wave of private innovation, the country is positioning itself as a global hub for unmanned systems from tactical defense drones to commercial logistics platforms.

But with this rapid growth comes a critical challenge: GNSS reliability. The same dense RF environments and regional interference that affect defense operations can also disrupt commercial UAVs and autonomous systems. In a country where unmanned solutions are becoming essential for both security and economic progress, navigation resiliency is no longer optional; it’s strategic.

That’s why infiniDome’s partnership with Globaz, a leading Indian defense and aerospace group, marks a major step in strengthening India’s navigation ecosystem. Together, we’re bringing field-proven GNSS protection technology directly to the Indian market — integrating local manufacturing, customer service, and technical support to ensure smooth deployment and long-term reliability.

“India isn’t just a customer,” says infiniDome’s CEO, Omer Sharar. “It’s a strategic partner in shaping the global standard for resilient navigation.”

As India expands its UAV fleets for defense, border surveillance, and commercial use, protecting navigation is key to ensuring that innovation translates into operational success.

What began as a defense necessity is becoming vital for every connected system on Earth.

For decades, GPS jamming was a problem reserved for the military. But in the last three years, that reality has changed dramatically. Today, civilian and commercial platforms, from autonomous trucks to shipping fleets and surveying drones, are increasingly exposed to interference that can cripple operations and endanger safety.

As more systems rely on GNSS for precise positioning, timing, and synchronization, their vulnerability grows. The result: rising awareness across industries that resilient navigation isn’t just a defense concern, it’s a business continuity concern.

At infiniDome, we’ve been leading this transition from the defense world to the commercial one. Our compact and cost-effective protection systems, like SunStone, are specifically designed for integration into civilian UAVs, autonomous vehicles, and industrial robotics. They combine the same battle-proven protection technology trusted by defense customers with the flexibility, low power, and small form factor demanded by commercial users.

In recent field deployments, our systems have ensured that delivery drones complete their routes despite nearby jamming sources, and that autonomous boats collecting environmental data in the Red Sea maintained positioning accuracy even in interference-heavy zones.

The future of GNSS isn’t just about precision, it’s about reliability. As industries digitize and autonomy expands, protecting the signal becomes protecting the mission itself.

infiniDome’s mission is simple: to ensure that when the world goes autonomous, it never loses its way.

The global rise of drones brings new opportunities – and new vulnerabilities.

The UAV market is exploding. From defense operations to delivery, inspection, and mapping, drones are everywhere. According to Markets & Markets, the global UAV market is expected to surpass $90 billion by 2030. But with growth comes exposure.

As skies become more crowded, they also become more contested. GNSS interference, once an occasional issue, is now a widespread challenge. UAV operators across Europe, India, and the Middle East are reporting signal disruptions that can instantly cripple entire fleets.

infiniDome’s mission has always been clear: to keep UAVs flying, even when the signal doesn’t cooperate. Our lightweight, easy-to-integrate anti-jamming modules give drones the same level of navigation resilience once reserved for military systems – without compromising size, power, or cost.

For UAV manufacturers, integrators, and end-users, GNSS protection isn’t just about technology – it’s about trust. It’s the invisible layer that ensures safety, reliability, and mission continuity.

Modern warfare has moved into the invisible domain – and GPS is the first to be attacked

In recent years, the electromagnetic spectrum has become the most contested battlefield in modern warfare. Across Israel, Ukraine, and the Red Sea, GNSS jamming is redefining how missions are fought and how they fail.

Losing GPS doesn’t just mean losing location – it means losing coordination, timing, and control. And that’s why navigation resiliency is now one of the most strategic capabilities any defense or unmanned platform can have.

At infiniDome, we’ve seen this transformation first-hand. Our systems have been deployed in real-world missions under heavy jamming conditions – keeping UAVs and autonomous vehicles operational where others failed. These experiences shape every product we design: from the compact GPSdome2 to the multi-layered Aura system, developed together with Honeywell Aerospace for defense-grade resilience.

Modern warfare no longer begins with a shot fired – it begins with a signal lost.
→ Discover how our technology ensures that your mission stays locked, connected, and on course – even when GPS doesn’t.

GNSS interference across Europe is no longer an exception; it’s becoming the environment we operate in.

In 2025, Europe is facing a challenge that was once reserved for conflict zones: GPS and GNSS interference. Reports show thousands of interference events recorded across the continent, from the Baltic to the Mediterranean. Pilots, drone operators, and maritime navigators are learning that loss of GPS is no longer rare. It’s routine.

At infiniDome, we’ve been following this trend closely. The rise in jamming and spoofing isn’t only a military concern – it’s a commercial one. Critical sectors like logistics, aviation, railways, and agriculture all depend on satellite-based navigation. When those signals fail, operations freeze.

This is exactly why we develop and continuously evolve our GNSS protection systems. Our goal is to ensure that even when interference becomes the new normal, navigation continuity remains guaranteed. Systems like GPSdome2, SunStone, and Resilient Navigation System are already protecting UAVs and vehicles across Europe, enabling them to stay on course even in high-interference zones.

The reality is clear: Europe’s skies are changing. Resilience is not an upgrade; it’s a necessity.

→ Learn more about how infiniDome protects navigation across interference-heavy regions.

GNSS Protection is a layered approach to defending positioning, navigation and timing systems against jamming and other sources of signal disruption. It can combine interference detection, anti-jamming technology, controlled reception pattern antennas, navigation integrity monitoring and complementary sensors such as inertial navigation systems. The objective is to preserve access to GNSS signals and maintain reliable navigation and operational continuity when those signals become degraded or unavailable.

Global Navigation Satellite Systems support far more than the map displayed on a vehicle or control station. GPS, Galileo, GLONASS and BeiDou provide essential positioning, navigation and timing data to UAVs, defense platforms, maritime vessels, autonomous vehicles, telecommunications networks and critical infrastructure. When that data is lost or becomes unreliable, the consequences may include navigation errors, mission interruption, unsafe autonomous behavior, loss of timing synchronization and disruption of downstream systems.

This dependency makes GNSS Protection a fundamental requirement for platforms operating in congested, unpredictable or contested radio-frequency environments. Effective protection must address the complete PNT chain, from the antenna receiving the satellite signals to the system evaluating whether the resulting position and time information meets operational requirements.

What Is GNSS and Why Is It Vulnerable?

GNSS is the collective term for satellite constellations that transmit signals used to calculate position, velocity and precise time. GPS is the United States system, while Galileo, GLONASS and BeiDou are operated by the European Union, Russia and China respectively. A multi-constellation receiver may process signals from several of these systems, providing access to more satellites and potentially improving availability and positioning performance.

Navigation satellite signals travel thousands of kilometers before reaching Earth. By the time they arrive at a receiver, they are extremely weak. This is sufficient for a properly designed receiver in a clean signal environment, but it also means that nearby radio-frequency energy can overwhelm the satellite signals and disrupt reception.

The source does not always have to be a sophisticated military system. GNSS performance can be affected by low-cost jammers, faulty transmitters, nearby communication equipment, antenna installation problems and even electronic components located on the protected platform itself. In hostile environments, deliberate jamming may be used to deny access to satellite navigation.

Using several satellite constellations or frequencies can improve redundancy, but it does not make a receiver immune to interference. A sufficiently powerful or wideband source may affect multiple frequencies or constellations simultaneously. For this reason, multi-constellation reception should be treated as one resilience layer, rather than a complete GNSS Protection strategy.

Which Threats Does GNSS Protection Address?

A professional GNSS Protection architecture begins by distinguishing between the different conditions that can affect a receiver. Deliberate jamming, unintentional RF interference, multipath and signal obstruction do not behave in the same way, and they cannot always be detected or mitigated using the same method.

GNSS Jamming

GNSS jamming occurs when radio-frequency energy interferes with the weak signals received from navigation satellites. If the interference is strong enough, an unprotected receiver may lose satellite tracking, become unable to calculate a valid position or continue producing degraded information.

Jamming signals can take several forms. A narrowband jammer concentrates energy within a limited part of the spectrum, while a broadband jammer affects a wider frequency range. Pulsed and chirp jammers use changing or intermittent waveforms that may require more advanced detection and mitigation. A platform can also face multiple interference sources arriving from different directions at the same time.

To understand how these threats affect navigation in practice, explore infiniDome’s live GPS interference map, which visualizes reported areas of GNSS disruption around the world.

Unintentional RF Interference

Not every GNSS failure is the result of an attack. Adjacent-band transmissions, damaged electronic equipment, poorly shielded cables and onboard radios or computers can introduce interference. On UAVs and other compact platforms, components are often installed close together, increasing the possibility of self-interference.

A good protection program therefore includes electromagnetic compatibility analysis and platform-level testing. Installing an advanced anti-jamming system without investigating the surrounding RF environment may leave avoidable performance problems unresolved.

Multipath and Environmental Degradation

GNSS signals can reflect from buildings, terrain, metallic structures and the surface of the water before reaching the receiver. These reflected signals are known as multipath and can reduce accuracy even when no deliberate interference is present.

Multipath is particularly relevant in cities, ports, industrial facilities and other environments with obstructed satellite visibility. It is not equivalent to hostile jamming, so it may require receiver processing, appropriate antenna placement and navigation integrity monitoring rather than spatial anti-jamming alone.

Physical obstructions can also limit the number of satellites visible to the receiver. Buildings, terrain and parts of the platform itself may block signals and reduce positioning availability. These conditions require attention to antenna installation and complementary navigation capabilities.

How Does a GNSS Protection System Work?

GNSS Protection is not a single filter or antenna. It is a process that detects changes in the signal environment, mitigates interference where possible, evaluates whether the navigation solution remains reliable and activates additional navigation sources when necessary.

In an antenna-based anti-jamming system, multiple antenna elements receive the RF environment from slightly different spatial positions. The system analyzes the relative phase and amplitude of the received signals to identify interference arriving from particular directions. It can then adapt the antenna reception pattern, reducing sensitivity toward those directions while preserving reception of satellite signals as far as the system design and operating conditions allow.

A simplified protection process may include:

1. Monitor the RF environment: The system analyzes signal power and other RF characteristics for abnormal conditions.
2. Detect and characterize interference: Depending on its capabilities, the system identifies characteristics associated with narrowband, broadband, pulsed, chirp or multi-source interference.
3. Assess spatial characteristics: A multi-element antenna array can use differences between its elements to support spatial interference suppression.
4. Apply spatial or frequency-domain mitigation: Adaptive processing creates reduced-gain regions toward interference sources or filters unwanted energy from the signal path.
5. Evaluate navigation integrity: The receiver or navigation computer checks whether position, velocity and timing outputs remain within acceptable operational limits.
6. Compare independent sensors: GNSS information can be compared with inertial, odometry, radar, visual or other navigation data.
7. Enter a degraded or GNSS-denied mode: If GNSS no longer meets operational requirements, the platform uses available complementary navigation sources according to predefined operational logic.
8. Recover safely: When the RF environment improves, the system verifies GNSS performance before allowing it to become a primary navigation input again.

The exact architecture depends on the protected platform. A lightweight UAV, a military ground vehicle and a fixed timing installation have different performance requirements, threat profiles and physical constraints. GNSS Protection therefore has to be engineered around the mission rather than added as a generic accessory.

For a focused explanation of the interference mitigation layer, read what GNSS jamming is and how anti-jamming works.

GNSS Anti-Jamming, Navigation Integrity and Resilient PNT

These terms are related, but they describe different protection objectives. Understanding their roles helps define what each layer contributes to the navigation architecture.

Anti-jamming primarily protects signal availability. Navigation integrity monitoring evaluates whether position, velocity and timing outputs remain suitable for the application. Resilient PNT addresses the broader operational requirement: how the platform will continue to navigate or maintain timing if GNSS is degraded or fully denied.

This distinction matters because keeping a GNSS receiver locked does not by itself guarantee that its output meets the accuracy requirements of the mission. Similarly, identifying excessive navigation uncertainty does not provide an alternative navigation solution. A mission-critical platform may require all three capabilities to support continuity during interference.

What Is a CRPA and How Does It Protect GNSS?

A Controlled Reception Pattern Antenna, or CRPA, is a multi-element antenna array that can dynamically adapt its reception pattern. Instead of receiving the RF environment in the same way from every direction, the system uses spatial processing to reduce antenna gain toward detected interference sources.

One common technique is null steering. A null is a direction in which the antenna array is configured to have very low sensitivity. The system can adapt its reception pattern to place nulls toward interference, suppressing unwanted energy before the protected signal reaches the GNSS receiver.

Beamforming is related but conceptually different. Rather than concentrating only on suppressing an unwanted direction, beamforming adjusts the array to increase sensitivity toward desired signal regions. Depending on the implementation, a GNSS Protection system may use a combination of spatial filtering techniques.

The number of antenna elements, system architecture and processing capability influence how many independent interference directions can be addressed and how effectively they can be suppressed. Real-world performance also depends on jammer power, geometry, platform dynamics, antenna installation and the surrounding RF environment.

CRPA technology can provide strong anti-jamming performance, but it is not a guarantee of uninterrupted and perfectly accurate navigation under every condition. It should be integrated with receiver monitoring, platform logic and complementary sensors according to the mission risk.

Why Is GNSS Protection More Than an Anti-Jamming Antenna?

An anti-jamming antenna protects an important part of the signal chain, but navigation resilience involves more than keeping RF interference away from a receiver. The system must also determine whether the resulting navigation information is reliable enough to support the platform’s operation.

A complete architecture may combine:

• A protected antenna and adaptive anti-jamming processing
• A compatible single-band or multi-band GNSS receiver
• Jamming and RF interference detection
• Position, velocity and timing integrity checks
• Inertial measurement and inertial navigation
• Radar velocity sensing or odometry
• Visual navigation or terrain-referenced navigation
• Sensor-fusion algorithms
• Operational alerts, logging and fallback behavior

The appropriate combination depends on how long the platform must operate without usable GNSS and how much position drift it can tolerate. An INS can provide continuous motion estimates during a GNSS outage, but inertial errors generally accumulate over time. Radar, visual navigation or other absolute and relative measurements can help constrain that drift, although they also depend on environmental and operational conditions.

This is why resilient navigation is designed as a system of complementary layers. No individual sensor performs perfectly in every environment, but well-designed sensor fusion can reduce dependence on any single source and support continuity when one input becomes degraded or unavailable.

Which Platforms Need GNSS Protection?

GNSS Protection is most important wherever the loss or degradation of PNT data could compromise safety, mission objectives, asset control or essential services.

GNSS Protection for UAVs and UAS

UAVs use GNSS for waypoint navigation, position holding, route execution, return-to-home functions and coordination with control systems. A disrupted signal can cause loss of navigation accuracy, flight-mode changes, deviation from the mission route or activation of an unsuitable failsafe response.

The protection solution must be selected with strict size, weight and power constraints in mind. It should also be evaluated as part of the complete aircraft, including the autopilot, antennas, onboard transmitters and fallback navigation logic. infiniDome provides dedicated solutions for aerial vehicle GNSS protection and compact platforms that need to maintain operational continuity in contested environments.

GNSS Protection for Ground Vehicles

Military and autonomous ground vehicles depend on PNT for route planning, mapping, coordination and sensor alignment. Buildings, terrain and onboard electronics can already make the RF environment difficult before deliberate interference is introduced.

A ground vehicle may have more space and power available than a small drone, but it can also face complex signal reflections and interference sources located near the horizon. GNSS Protection should therefore be integrated with inertial sensing, odometry and other available vehicle data.

GNSS Protection for Maritime Platforms

Maritime vessels use GNSS for navigation, route keeping, operational coordination and, in some applications, dynamic positioning. Unmanned surface vehicles may be particularly dependent on continuous and reliable positioning because there is no onboard operator to assess visual conditions and intervene.

Signals can also travel over open water with fewer physical obstructions, allowing interference to affect a wide area. The navigation architecture should consider how the vessel will detect degraded positioning performance and continue operating safely when satellite navigation becomes unreliable.

GNSS Protection for Autonomous Systems

Autonomous platforms need more than continuous position data. They need position data that meets the accuracy and reliability requirements of the algorithms controlling movement and making operational decisions.

GNSS often provides an absolute reference used to correct the drift of relative sensors. If that reference becomes degraded or unavailable, navigation uncertainty can increase. GNSS Protection for autonomous vehicles should therefore include integrity monitoring and predefined behavior for degraded or denied conditions, rather than relying only on the continued presence of a GNSS fix.

GNSS Protection for Critical Infrastructure

Critical infrastructure frequently uses GNSS for precise timing rather than physical navigation. Telecommunications networks, electricity grids, financial systems, data centers and transportation infrastructure may rely on synchronized time for network operation, monitoring, transaction processing and control.

In these environments, the key question is not whether a vehicle will remain on course, but whether the organization can maintain accurate timing when GNSS reception is disrupted or unavailable. Protection may combine interference-resistant reception, timing integrity monitoring, holdover clocks and independent timing sources. Learn more about the role of resilient PNT in critical infrastructure.

How Do You Choose the Right GNSS Protection Solution?

The most suitable solution is determined by the mission and threat model, not by a single product specification. An engineering team should first identify what the platform must continue doing during interference and which degree of degradation is acceptable.

Important selection questions include:

• Which GNSS constellations and frequency bands does the platform use?
• Is the principal risk deliberate jamming, unintentional interference, environmental signal degradation or a combination?
• How many simultaneous interference directions must the system address?
• Does the platform need to maintain a position fix or detect when GNSS performance falls below an acceptable threshold?
• How long must navigation continue if GNSS becomes fully unavailable?
• What are the platform’s size, weight, power and cooling limitations?
• Can the existing GNSS receiver and autopilot remain in place?
• Is the solution intended for retrofit installation or OEM integration?
• Which inertial and complementary sensors are already available?
• What interfaces, protocols and environmental standards must be supported?
• How will the complete system be tested under representative conditions?
• What should the platform do when navigation confidence falls below an acceptable threshold?

The answer may be a compact anti-jamming add-on, an OEM module or a more comprehensive resilient navigation architecture. For example, SunStone is designed as a compact GNSS anti-jamming solution for platforms where dimensions, weight and power consumption are important integration considerations. An OEM configuration may be more suitable when protection is being incorporated directly into the platform’s design.

The Protection Radius Calculator can also support early scenario evaluation, but simulated results should not replace platform-specific engineering and testing.

How Is GNSS Protection Performance Evaluated?

A strong product comparison should not rely on a single headline number. GNSS Protection performance is influenced by the threat waveform, jammer power, distance, direction, antenna geometry, supported bands and behavior of the protected receiver.

Relevant evaluation criteria include:

• Supported GNSS constellations and frequency bands
• Maximum number of simultaneously addressed interference directions
• Interference or jammer suppression performance
• Detection time and mitigation response
• Position, velocity and timing error during interference
• Continuity and availability of the navigation output
• Receiver recovery and reacquisition time
• Performance during motion, vibration and changing jammer geometry
• Resistance to narrowband, broadband, pulsed and chirp interference
• Interference-detection reliability and false-alarm behavior
• Power consumption, weight, dimensions and thermal requirements
• Environmental durability and interface compatibility

Testing should represent the intended platform as closely as possible. Bench testing is useful for controlled comparison, but it may not reproduce antenna obstruction, platform emissions, vibration, multipath or rapidly changing interference directions. A mature validation process includes component-level testing, integration testing and representative operational scenarios.

It is also important to define success in advance. For one platform, success may mean maintaining a valid GNSS solution. For another, it may mean detecting degraded GNSS quickly enough to transition safely to inertial navigation. In a timing system, the priority may be limiting time error during an outage. The performance metric must reflect the actual operational requirement.

How Does Resilient Navigation Work in a GNSS-Denied Environment?

A GNSS-denied environment is one in which the platform cannot obtain a sufficiently reliable satellite-navigation solution. In this condition, anti-jamming technology may still reduce interference, but the system must be prepared for situations in which protected GNSS is not enough.

The navigation computer can continue estimating movement using an INS, which measures acceleration and rotation. Depending on the platform, inertial data may be combined with radar velocity, wheel odometry, visual information, terrain references or other measurements. Sensor-fusion algorithms compare the available inputs, estimate their uncertainty and produce a navigation solution from the available data.

The key challenge is error growth. Without an external absolute reference, inertial navigation can drift over time. The rate of drift depends on sensor quality, calibration, motion and the availability of other measurements. A resilient navigation design must therefore specify how long the required accuracy can be maintained and what happens when uncertainty exceeds the mission limit.

infiniDome’s Resilient Navigation System combines protection and complementary navigation layers to support continuity when GNSS becomes degraded or unavailable. The correct architecture still depends on platform requirements and should be validated for the intended operating environment.

GNSS Protection Solutions from infiniDome

infiniDome develops GNSS Protection and resilient navigation technologies for UAVs, unmanned systems, defense platforms, commercial vehicles and critical applications. Its solutions are designed to provide protection while addressing practical integration constraints such as size, weight, power consumption, receiver compatibility and platform architecture.

Rather than treating every GNSS-dependent system in the same way, infiniDome offers configurations for different levels of integration and operational resilience. These include compact anti-jamming products, OEM modules and systems that combine protected GNSS with additional navigation technologies.

Selecting the right solution begins with several practical questions: What must remain operational during interference? Which interference conditions are expected? How much space and power are available? How long must the platform navigate if GNSS is unavailable? The answers define whether the requirement is primarily GNSS anti-jamming, broader GNSS Protection or a complete resilient navigation system.

Frequently Asked Questions About GNSS Protection

What is GNSS Protection? +

GNSS Protection is the combination of technologies and operating strategies used to defend satellite-based positioning, navigation and timing from jamming, unintentional interference and signal loss. Depending on the application, it may include anti-jamming processing, CRPA technology, interference detection, integrity monitoring and complementary navigation sensors.

What is the difference between GPS Protection and GNSS Protection? +

GPS Protection refers specifically to protecting signals from the United States Global Positioning System. GNSS Protection is the broader term because it can include GPS as well as Galileo, GLONASS, BeiDou and other satellite-navigation systems. In practice, the terms are sometimes used interchangeably, but GNSS is more accurate when multiple constellations are supported.

What is the difference between GNSS jamming and unintentional interference? +

GNSS jamming involves the deliberate transmission of radio-frequency energy to disrupt satellite-signal reception. Unintentional interference can result from nearby transmitters, faulty equipment, poorly shielded electronics or emissions from the platform itself. Both can reduce GNSS performance, but identifying the source helps determine the appropriate mitigation measures.

Is GNSS anti-jamming the same as resilient navigation? +

GNSS anti-jamming helps preserve access to satellite signals during interference. Resilient navigation combines protected GNSS with complementary sensors and operational logic so that a platform can continue navigating when satellite reception becomes degraded or unavailable. Anti-jamming is therefore one layer within a broader resilient navigation architecture.

What is a CRPA anti-jamming antenna? +

A CRPA is a multi-element antenna array that adapts its reception pattern in response to interference. By analyzing how signals arrive at the different antenna elements, it can reduce sensitivity toward jammer directions while preserving reception of GNSS signals. Its performance depends on array design, processing capability, jammer geometry and system integration.

Can GNSS Protection work with an existing receiver? +

Some GNSS Protection systems are designed as add-on solutions that operate between the antenna system and an existing GNSS receiver. This can reduce integration complexity because the platform may not need to replace its established receiver or navigation computer. Compatibility, supported frequencies, antenna configuration, interfaces and system behavior must still be verified.

Does using multiple GNSS constellations prevent jamming? +

No. Multi-constellation reception improves satellite availability and redundancy, but it cannot guarantee protection against jamming. A wideband or sufficiently powerful interference source may affect several frequencies and constellations. Multi-constellation and multi-frequency reception are useful resilience layers, but they should be combined with detection, mitigation and operational fallback measures.

Can a drone continue flying during GPS jamming? +

A drone may continue flying if it has suitable GNSS anti-jamming protection, stable flight-control logic and complementary navigation sensors. The result depends on jammer strength, geometry, platform integration and the drone’s response to degraded navigation. A complete solution must address both preservation of GNSS and safe behavior if GNSS becomes unavailable.

Can an INS replace GNSS? +

An INS can continue estimating motion without satellite signals, but its errors generally accumulate over time. GNSS provides an absolute position and velocity reference that helps correct this drift. For extended GNSS-denied operation, an INS is often combined with radar, odometry, vision or other sensors rather than treated as a permanent one-for-one replacement.

How many jammers can a GNSS Protection system suppress? +

The answer depends on the antenna array, number of elements, processing architecture, frequency support and threat geometry. Product specifications may describe the number of simultaneous directions a system is designed to mitigate, but actual performance should be assessed under representative conditions. Multiple jammers located in similar directions may also behave differently from spatially separated sources.

How should GNSS Protection be tested? +

Testing should include representative interference waveforms, power levels, directions, platform motion and antenna installation conditions. Evaluation should measure not only signal suppression, but also position and timing accuracy, continuity, detection time, recovery and behavior of the complete navigation system. Field and platform-level validation should complement laboratory testing.

Build Navigation Resilience Around the Mission

GNSS interference is no longer limited to exceptional military scenarios. It can affect defense operations, autonomous platforms, commercial fleets and infrastructure that depends on accurate positioning or synchronized time. The right response is to design a layered GNSS Protection architecture around the platform’s risks, constraints and continuity requirements.

infiniDome develops compact anti-jamming technology and resilient navigation solutions designed to help platforms maintain reliable PNT in disrupted and contested environments. To identify the appropriate protection architecture for your UAV, vehicle, vessel or critical system, contact infiniDome and discuss your platform, threat model and integration requirements with the team.

Picture a world where the guiding intelligence of drones and UAVs is abruptly silenced, their navigational prowess rendered useless – a scenario that is part of the reality because GPS jamming attacks.

The prevalence of GPS jamming attacks poses a significant threat to unmanned aerial vehicles (UAVs) and drones, and any other applications that depend on GNSS signals to navigate, disrupting their navigation capabilities with potentially severe consequences.
When subjected to a jamming attack, these devices lose their ability to receive accurate positioning data, leading to complete loss of control.

In real-world scenarios, a drone or UAV experiencing a jamming attack may deviate from its intended course, endangering both the equipment and any payload it may carry.
Moreover, the loss of navigational control can impact critical missions, including surveillance, reconnaissance, and emergency response operations,
The consequences extend beyond financial losses to potential security risks, making it imperative for industries relying on unmanned systems to address the vulnerabilities associated with GPS disruptions.

To mitigate the risks, investing in GPS protection and resilient navigation solutions is crucial. These technologies not only detect and counteract jamming attempts but also ensure the continuity of operations that can be and will be a game changer.

The urgency to enhance GPS resilience stems from the growing reliance on unmanned systems in critical sectors, including transportation, agriculture, and public safety. As these systems become more integrated into our daily lives, the potential fallout from GPS disruptions becomes increasingly severe. For instance, in agriculture, drones are used for precision farming, monitoring crop health, and optimizing resource allocation. A GPS disruption could lead to misapplication of resources, affecting crop yields and sustainability.
