Abstract
La présente invention concerne un procédé (50) d'estimation d'attitude d'un satellite (20), ledit satellite étant configuré pour générer et pour émettre un premier signal de référence sur un lien descendant au moyen d'une première antenne d'émission (21), et pour retransmettre des signaux utiles sur le lien descendant au moyen d'une seconde antenne d'émission (23), comportant des étapes de : - émission (51) par une station sol d'un second signal de référence, - retransmission (52) par le satellite du second signal de référence, - réception (54) du premier signal de référence et du second signal de référence par au moins trois stations de mesure (31), - calcul (55), pour chaque station de mesure (31), d'une mesure différentielle de puissance entre les puissances respectives du premier signal de référence et du second signal de référence, - estimation (56) de l'attitude du satellite en fonction des mesures différentielles de puissance calculées.The present invention relates to a method (50) for estimating the attitude of a satellite (20), said satellite being configured to generate and to transmit a first reference signal on a downlink by means of a first antenna. transmission (21), and to retransmit useful signals on the downlink by means of a second transmission antenna (23), comprising the steps of: - transmission (51) by a ground station of a second reference signal , - retransmission (52) by the satellite of the second reference signal, - reception (54) of the first reference signal and of the second reference signal by at least three measuring stations (31), - calculation (55), for each measurement station (31), a differential power measurement between the respective powers of the first reference signal and of the second reference signal, - estimation (56) of the attitude of the satellite as a function of the calculated differential power measurements.
