How rapid angular velocity and 30 dB higher signal power from Low Earth Orbit satellites overcome traditional GPS outages in dense cities.
In city centers with skyscrapers, tall glass towers block line-of-sight satellite signals and create severe multipath reflections that cause 50-meter positioning errors. GlobalNavSat utilizes LEO satellite Doppler signatures: because LEO satellites move across the sky at 7 km/s, their rapidly changing frequency shifts yield centimeter-accurate position fixes even inside multi-story parking garages.
