NASA's Reliable Geo-Limitation Algorithm for Unmanned Aircraft
NASA Langley Research Center has developed a an assured safety net technology for UAS, Safeguard, that can alleviate hazards with unmanned aircraft (UA) flying beyond their authorized perimeters and into no-fly zones. Safeguard works by continuously detecting a UAs proximity to virtual perimeters established around no-fly-zones (i.e., stay-out or stay-in regions and altitude limits), and taking action to guarantee the perimeters are not breached. The key to the design is streamlined functionality that has been formally verified to guarantee detection of possible perimeter violations. Safeguard is applicable to both rotary- and fixed-wing systems and substantially outperforms embedded geo-fences in terms of reliably and dependably stopping excursions into no-fly zones. Safeguard has the potential to provide a means to comply with pending regulatory directives for geo-limitation for a burgeoning UAS industry.
