Abstract
(EN)
The present invention relates to a method (50) for calibrating space errors induced by phase biases having a detrimental effect on the measurements of phase differences of radio signals received by three unaligned receiving antennas of a vehicle. The method (50) comprises the steps (52, 54) of estimating an inter-satellite angular deviation of a pair of satellites in two different ways: i) on the basis of the respective positions of the vehicle and of the satellites, so as to obtain a theoretical inter-satellite angular deviation; and ii) on the basis of the respective directions of incidence of the satellites relative to the vehicle, which are determined from phase measurements, so as to obtain an estimated inter-satellite angular deviation. The method (50) comprises the step (55) of estimating the space errors on the basis of said theoretical and estimated inter-satellite angular deviations. The present invention also relates to a method and system for estimating the attitude of a vehicle, in particular a spacecraft.

La présente invention concerne un procédé (50) de calibration d'erreurs spatiales, induites par des biais de phase affectant des mesures de différences de phase de signaux radioélectriques reçus par trois antennes de réception non alignées d'un engin. Le procédé (50) comporte des étapes (52, 54) d'estimation d'un écart angulaire inter-satellites d'une paire de satellites de deux façons différentes : i) en fonction des positions respectives de l'engin et des satellites, pour obtenir un écart angulaire inter-satellites théorique, et ii) en fonction des directions d'incidence respectives des satellites par rapport à l'engin, déterminées à partir de mesures de phase, pour obtenir un écart angulaire inter-satellites estimé. Le procédé (50) comporte une étape (55) d'estimation des erreurs spatiales en fonction desdits écart angulaire inter-satellites théorique et estimé. La présente invention concerne également un procédé et un système d'estimation d'attitude d'un engin, notamment spatial.
