A Navy-backed test showed a commercial receiver tracking a live C‑band navigation signal in real time, pointing to a practical backup when GPS is jammed.
Story Snapshot
- A NovAtel receiver tracked a live TrustPoint C‑band signal during a real pass.
- TrustPoint says the signal produced usable positioning under GPS interference.
- The work ran under a U.S. Navy Small Business Innovation Research Phase II contract.
- The partners also ran a lab test with a basic high‑power jammer.
What The Test Proved And Why It Matters
TrustPoint and Hexagon’s NovAtel ran a live-sky trial where a NovAtel receiver acquired and tracked a C‑band navigation signal sent from a TrustPoint satellite. The companies called this an industry first on a commercial receiver platform and said the signal enabled positioning when Global Positioning System signals were degraded or denied. The test addresses a growing need: military and critical services face routine jamming and spoofing, so leaders want layered positioning, navigation, and timing that does not fail if one system is hit.
SpaceNews reported that NovAtel captured the live signal during a satellite pass and that the team also used a lab setup with a wideband, high‑power jammer to gauge baseline anti‑jam behavior. TrustPoint’s statement said the demonstration confirmed that C‑band signals can be acquired, tracked, and used to generate precise positioning data in contested radio‑frequency space. While the partners highlighted the breakthrough, they did not publish raw receiver logs or detailed error data in public materials, limiting outside review of exact performance numbers.
Navy Program Backing And Defense Use Cases
The effort operated under a Small Business Innovation Research Phase II award led by the Naval Air Warfare Center Aircraft Division, placing it within a documented Navy program path. Reporting also ties the work to the U.S. Naval Air Systems Command’s push for assured navigation in jammed zones. A related award description called for a commercial prototype receiver and a multi‑element C‑band antenna that can deliver time and position without Global Positioning System when L‑band is jammed or spoofed—clear signs of the military need behind the test.
TrustPoint’s recent funding history shows continued federal interest in Global Positioning System‑independent services. The company won a U.S. Space Force Tactical Funding Increase contract in 2026 to demonstrate end‑to‑end positioning, navigation, and timing outside of Global Positioning System, and it previously advanced a Navy Phase II selection focused on C‑band assured positioning, navigation, and timing. TrustPoint has also launched multiple satellites, which supports the claim that a live in‑orbit signal was available for receiver testing in the first place.
How C‑Band And Low Earth Orbit Can Add Resilience
C‑band navigation from low Earth orbit can add diversity to the radio picture. Signals from lower altitude can be stronger at the ground, arrive from a faster‑moving source, and occupy different frequencies than the crowded Global Positioning System bands. Researchers and planners have promoted a “layered” model that mixes sources, frequencies, and antennas to ride through local jamming or spoofing events. The TrustPoint‑NovAtel trial fits that trend by showing a non‑Global Positioning System signal working on familiar commercial hardware.
NovAtel has published and presented work on jamming and spoofing detection and mitigation in prior test campaigns, which helps explain how a mainstream receiver platform could adapt to a new signal and band. In this case, the partners described “enhancements” to a NovAtel receiver but did not release the exact firmware or front‑end changes. Even so, the claim that a trusted commercial receiver tracked a live C‑band navigation signal under interference aligns with the defense goal of fielding solutions without exotic, one‑off gear.
What Comes Next: From Demo To Deployable Layer
Next steps will likely focus on publishing performance numbers that operators care about: acquisition time, carrier‑to‑noise density, track stability, and position and time error under different jammer types. Government customers will also want range testing against more complex, operational jammers to map real‑world limits. Contract deliverables and test plans from the Phase II program could clarify acceptance criteria and help translate the demo into tactics and procurement decisions.

For readers who worry about fragile systems and rising threats, the signal here is practical: do not bet the country on a single band or a single constellation. A layered setup that blends Global Positioning System with C‑band from low Earth orbit and smart receivers can keep planes flying, grids stable, and supply lines moving even when bad actors try to blind them. That is a concrete step toward making vital services less dependent on politics, budgets, or bureaucracy.
