An aircraft Doppler system, characterized by means for directing electromagnetic signals transmitted to ground on each side of a ground track, means for receiving Doppler echo signals containing drift and velocity information with respect to the ground from areas spaced at transverse direction with respect to said piece of land, means for deriving from said received Doppler echo signals analog signals containing differential Doppler frequency information representative of the speed of said aircraft with respect to the ground track, and means receiving the same. difference of said analog signals to produce a signal representative of the drift information.
