New RASR method enhances UAV navigation without GNSS

Researchers have developed a new method called Range-Aware Scale Recovery (RASR) to improve metric navigation for unmanned aerial vehicles (UAVs) when Global Navigation Satellite System (GNSS) signals are unavailable. RASR addresses the issue of inaccurate distance scale in outputs from dense pair-geometry foundation models, which are crucial for last-meter navigation. The system separates a core scale-recovery component from a protocol-specific calibration module, allowing for stable per-pair distance and heading estimates. In evaluations using the PairUAV protocol, RASR achieved a total score of 0.003189, demonstrating its effectiveness in providing accurate navigation data. AI
