An adaptive depolarisation cancellation method to reduce the uplink depolarised signal in future satellite systems is described. It is based on transmission of a small orthogonally polarised correction signal from the earth station. A data-acquisition method using only a single beacon signal transmitted from the satellite could provide the information required for generation of the correction signal.
