The Takeaway
Current GPS usually has a margin of error of several meters and can take a long time to 'fix' its precision. By using the rapid motion of Low-Earth Orbit satellites (like Starlink), researchers achieved a 100x improvement in accuracy, which is the key needed for safe autonomous drones and self-driving cars.
From the abstract
The integration of non-terrestrial networks (NTN) into 5G new radio (NR) enables a new class of positioning capabilities based on cellular signals transmitted by Low-Earth Orbit (LEO) satellites. In this paper, we investigate joint delay-and-carrier-phase positioning for LEO-based NR-NTN systems and provide a convergence-centric comparison with Global Navigation Satellite Systems (GNSS). We show that the rapid orbital motion of LEO satellites induces strong temporal and geometric diversity acros
