Trillium Engineering Demonstrates GD-Loc on Competitive Group 2 UAS

HOOD RIVER, Ore. — May 6, 2025 — Trillium Engineering, a leader in advanced gimbaled imaging solutions, successfully demonstrated its GD-Loc solution last week using its leading HD55-MV mounted on an operational Group 2 uncrewed aircraft system (UAS). The flight marks a significant milestone in validating GD-Loc’s real-time, high-accuracy geolocation performance for GPS-degraded or denied environments.

Testing has confirmed GD-Loc's capability to consistently achieve CAT-1 geolocation accuracy. Notably, 20% of flight trials were executed under GPS-denied conditions, simulating a fully jammed environment. Preliminary analysis of these GPS-denied flights indicates sustained CAT-1 geolocation performance. These results underscore GD-Loc's significant advantage for modern ISR missions and builds upon Trillium's successful demonstration at the U.S. Army PNTAX event in September 2024, where GD-Loc reliably generated CAT-1 target coordinates under live GPS and communications jamming.

“Demonstrating GD-Loc’s performance on a competitive Group 2 UAS reinforces the flexibility and power of this capability,” said Dr. N. Andrew Browning, Chief Technology Officer at Trillium Engineering. “It’s a game-changing advancement for operators who need accurate geolocation when traditional GPS solutions are unavailable.”

Key GD-Loc features include:

• Accurate geolocation: Delivers CAT-1 coordinates – without GPS - at up to 5km for ISR and targeting.
• Seamless integration: Optimized for Trillium’s gimbaled systems and compatible with a wide range of UAS platforms.

To enhance mission success across a range of operational needs, Trillium Engineering is extending the availability of its advanced GD-Loc geolocation capability through joint integration with select partners.
