Abstract
A method for determining a position of a phase centre of an antenna arranged in a mobile device, in particular a vehicle, wherein the antenna is operable to receive satellite signals in a global navigation satellite system, the method comprising: receiving, with the antenna, satellite signals from satellites of the global navigation satellite system; determining a direction from which the satellite signals are received based on the received satellite signals; and determining the position of the phase centre of the antenna based on the direction from which the satellite signals are received and stored correlation information indicative of a correlation between the position of the phase centre and the direction from which the satellite signals are received.
