Case Study: Field-Proven GNSS Resilience for ISR Global’s Vehicle Monitoring Platform

Background:

In recent years, insurance companies have required vehicle monitoring systems as a condition for theft coverage. These systems rely on GNSS (GPS) to report real-time location data.

Criminals have adapted by using GNSS jammers to disable tracking, enabling vehicle theft without detection. This growing threat affects not only private luxury vehicles but also commercial trucks, delivery fleets, heavy machinery, and other high-value assets, leading to major financial and operational losses.

The Challenge:

ISR Global, a leading provider of tracking solutions for vehicles and heavy machinery, supplies these GPS-based monitoring systems to meet insurance requirements. While effective under normal conditions, these systems were vulnerable to jamming attacks, jeopardizing both the security of the vehicle and the validity of the insurance policy.

ISR Global sought to enhance its solution by integrating anti-jamming protection, ensuring its trackers would continue to function in real-world theft scenarios involving GNSS attacks.

The Solution:
To assess GNSS jamming resilience, a two-phase field test compared a standard ISR Global tracker with the same system enhanced by anti-jamming protection.

Phase 1: Unprotected System
A vehicle with a standard tracker was monitored by the control center. When a GNSS jammer was activated nearby, location data briefly appeared, but only engine status was transmitted. Once the jammer was placed inside the vehicle, the GPS signal was completely lost, even during a 1 km drive.

Phase 2: Protected System
The vehicle was then equipped with a tracker featuring anti-jamming protection and dual GPS antennas, alongside the unprotected unit. When jamming resumed, the standard tracker failed again, while the protected system maintained continuous real-time tracking, demonstrating full GNSS resilience under interference.

The Result:
The trial proved the clear advantage of integrating anti-jamming protection into ISR Global’s tracking system.
While the unprotected tracker lost positioning under jamming, the enhanced system maintained full GNSS functionality and real-time location reporting throughout the test, despite active interference from within the vehicle.
The results confirm that anti-jamming technology turns vulnerable trackers into resilient, theft-resistant monitoring tools, ensuring continuous operation when it matters most.
