Starlink Downlinks Become a Mock Navigation Constellation
Beam-specific orbit and clock models turn live Ku-band arrivals into meter-scale positioning and nanosecond timing in a field test.
Summary
Beam-specific orbit and clock models turn live Ku-band arrivals into meter-scale positioning and nanosecond timing in a field test.
A field experiment extracted time-of-arrival measurements from live Starlink downlinks and paired them with high-fidelity, beam-specific orbit and clock models distributed as though the constellation operator supplied them. The mock fused low-Earth-orbit navigation system reported 95% error bounds of 2.33 meters horizontally, 3.37 meters vertically and 11.19 nanoseconds in timing. Actual errors in the campaign remained inside those bounds despite consumer-grade receiver constraints. The method depends on precision data not available in ordinary opportunistic reception, so it demonstrates an architecture rather than a current public service.
