The present invention relates to a method (50) for estimating the attitude of a satellite (20), said satellite being configured to generate and transmit a first reference signal on a downlink by means of a first transmitting antenna (21), and to retransmit useful signals on the downlink by means of a second transmitting antenna (23), comprising the steps of: - transmitting (51) by a ground station of a second reference signal, - retransmitting (52) by the satellite of the second reference signal, - receiving (54) of the first reference signal and the second reference signal by at least three measuring stations (31), - calculating (55), for each measuring station (31), a differential power measurement between the respective powers of the first reference signal and the second reference signal, - estimating (56) the attitude of the satellite as a function of the calculated differential power measurements.
