Abstract
A method for estimating a position of a vehicle () relative to one or more radio transceivers (). The method including the steps of; obtaining propagation delay data associated with radio transmission between a vehicle transceiver () included in the vehicle () and the one or more radio transceivers (); obtaining vehicle motion data related to a trajectory of the vehicle (); 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 () and the vehicle transceiver (); 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 () relative to the one or more radio transceivers () based on the MPC tracks.
