Abstract

A method for estimating a position of a vehicle (100) relative to one or more radio transceivers (150). The method including the steps of; obtaining propagation delay data associated with radio transmission between a vehicle transceiver (110) included in the vehicle (100) and the one or more radio transceivers (150); obtaining vehicle motion data related to a trajectory of the vehicle (100); identifying one or more multipath components, MPC, in the propagation delay data, the MPC relates to a radio transmission propagation path between a fixed radio transceiver (150) and the vehicle transceiver (110); determining an MPC track for each identified MPC based on the vehicle motion data and on the propagation delay data, MPC track representing evolution of an MPC over time; and estimating the position of the vehicle (100) relative to the one or more radio transceivers (150) based on the MPC tracks.
