Abstract:	This paper studies the beamforming strategies of multiple-input multiple-output (MIMO) Starlink low Earth orbit (LEO) satellites. Applying a maximum likelihood (ML) estimation framework to the signal-to-noise ratio (SNR), the beam pattern of Starlink satellites is calculated and the beam switching schedule is estimated. Experimental results with received signals from six Starlink LEO satellites are presented demonstrating the beam switching strategy.
