Trillium Engineering, a leader in advanced gimbaled imaging solutions, has successfully demonstrated its GD-Loc geolocation technology on an operational Group 2 uncrewed aircraft system (UAS) equipped with the HD55-MV gimbal.
This flight marks a major milestone in validating GD-Loc’s ability to deliver real-time, high-accuracy geolocation performance in environments where GPS signals are degraded or entirely denied. The system consistently maintained Category 1 geolocation accuracy, pinpointing targets within six meters even without GPS access.
These results strengthen GD-Loc’s position as a critical enabler for modern intelligence, surveillance, and reconnaissance (ISR) operations. The demonstration builds on Trillium’s earlier success at the U.S. Army’s PNT Assessment Experiment (PNTAX) last September, where GD-Loc reliably produced Category 1 target coordinates despite 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 Features of GD-Loc:
- Accurate geolocation: Delivers Category 1 target coordinates—without GPS—at ranges up to 5 kilometers, supporting ISR and precision targeting.
- Seamless integration: Optimized for use with Trillium’s gimbaled systems and compatible with a wide variety of UAS platforms.
To support diverse mission requirements, Trillium Engineering is expanding the availability of its GD-Loc technology through collaborative integrations with select industry partners.
