Abstract:	This paper demonstrates the first Doppler positioning-based results with Starlink low Earth orbit (LEO) satellites. A cognitive opportunistic framework is used to detect Starlink’s LEO satellite signals and track the Doppler frequencies of each Starlink LEO satellite. To this end, a generalized likelihood ratio (GLR)-based test is developed to detect the LEO satellite signals and estimate their corresponding beacons. A chirp parameter estimator is also proposed to track the Doppler frequencies from the unknown Starlink signals. Experimental results are presented showing a horizontal positioning error of 10 m by tracking the Doppler of six Starlink LEO satellites.
