Optical Terrain Contour Matching (TERCOM) for True Resilience in GNSS-Denied Airspace
Core aerospace engineering and protocols for GPS-Denied Optical Navigation.
The Fragility of Satellite Navigation in Modern Conflict
Civilian and military drones depend heavily on GPS/GLONASS signals that originate from satellites 12,000 miles in space, producing faint radio signals on Earth that are trivially jammed or spoofed with inexpensive commercial radio transmitters.
Visual-Inertial Terrain Cross-Verification
UAVQuantum couples inertial measurement units with downward-facing optical cameras running visual odometry. The system compares optical ground landmarks against pre-cached satellite maps, allowing the aircraft to navigate through complete GPS blackouts with sub-meter accuracy.
- Visual-Inertial Odometry (VIO): Tracking position by analyzing ground feature movement at 60 FPS.
- Pre-Loaded Satellite Terrain Maps: Matching live camera views against onboard 3D terrain databases.
- GPS Spoofing Detection: Flagging sudden drift between satellite telemetry and visual optical flow.
- Autonomous Safe Return: Guiding the UAV safely back to friendly territory with zero satellite aid.
