GPS-Denied Drone Navigation

GPS signals are vulnerable to jamming, spoofing, and terrain obstruction, threatening autonomous vehicle operations. ANPC's Transponder Landing System (TLS) offers a GPS-independent positioning solution, currently used for manned military and research aircraft in complex terrain. This project demonstrated TLS as a viable drone navigation system by developing a GPS-TLS toggle algorithm capable of autonomously controlling a drone in GPS-denied environments. The system can maintain a maximum 10 ft deviation from a prescribed flight path at 100–400 ft AGL, reducing dependence on on-site pilots and enabling mission continuity where traditional navigation fails.
