This letter presents the first results of carrier phase tracking and positioning using Starlink's low earth orbit (LEO) satellite signals. An adaptive Kalman filter algorithm is proposed for tracking the carrier phase of unknown Starlink signals. The experimental results demonstrate successful carrier phase tracking of six Starlink satellites and achieve a horizontal positioning error of 7.7 m with known receiver altitude.
This letter shows the first carrier phase tracking and positioning results with Starlink's low earth orbit (LEO) satellite signals. An adaptive Kalman filter based algorithm for tracking the beat carrier phase from the unknown Starlink signals is proposed. Experimental results show carrier phase tracking of six Starlink satellites and a horizontal positioning error of 7.7 m with known receiver altitude.
