Case Study: How Rewind Ensures Accurate Carbon Storage in Anoxic Zones

Background:
Rewind is a marine terrestrial biomass storage company advancing a natural, scalable solution to remove atmospheric CO₂ and mitigate climate change. Their method uses trees to capture CO₂ and convert it to organic carbon, while deep, oxygen-free waters preserve it for geological time scales. This long-term approach not only reduces atmospheric CO₂ but also aligns with natural carbon cycles, offering a sustainable sequestration solution. At Rewind’s Epsilon pilot site, precision navigation is essential for deploying biomass, conducting environmental monitoring, and ensuring regulatory compliance—tasks that require reliable, uninterrupted positioning systems in remote areas with potential GNSS interference.

The Challenge:
Rewind faced persistent GNSS jamming at the Epsilon site, causing frequent navigation disruptions. This interference, from nearby signal jamming sources, led to partial or complete GPS loss. The impact was significant, halting deep-sea data sampling for months until the GPS signal was restored. These disruptions affected both the operational timeline and cost efficiency, with delays impacting resource allocation and project momentum.

The Solution:
To address this, Rewind collaborated with infiniDome to test the GPSDome2 anti-jamming system.
Testing was conducted on two vessels—a small boat and a larger ship—both equipped with the GPSDome2. The smaller vessel set out from Haifa harbor to the Epsilon site, enduring substantial jamming but successfully reacquiring GPS positioning once in a clearer zone. On the larger ship, where GPSDome2 was directly integrated with the vessel’s navigation system, positioning remained stable throughout, even in high-interference areas.

The Result:
The GPSDome2 system effectively maintained GNSS positioning in interference-heavy environments once an initial GPS fix was obtained. In both tests, it held stable data beyond 2.5 km offshore in minimal interference zones. After total signal loss from jamming, GPSDome2 quickly reacquired positioning upon entering a low-interference zone, allowing accurate navigation back to the Epsilon site. Integrating GPSDome2 into the ship’s navigation system provided real-time tracking and minimized operational disruptions, reducing potential economic impacts.
This successful test confirmed GPSDome2 as a reliable anti-jamming solution, enabling Rewind to operate safely and efficiently in interference-prone zones.
