Abstract: The invention relates to a method for calibrating an antenna of a receiver of signals (s1, . . . , sN) originating from a plurality of sources, said receiver comprising a plurality of sensors (c1, . . . , cM), characterized in that it comprises the following steps: measurement of a phase shift (dm,n measure) for each of the sensors (c1, . . . , cM) on each of the signals (s1, . . . , sN), determination of at least one attitude value of the antenna, said attitude being defined by a set of coordinates, calculation, for each of the sensors on each of the signals, of a theoretical phase shift (dm,n theoretical) as a function of the attitude of the antenna, from the directions of arrival of the signals, calculation of a bias (β1 sensor m) for each of the sensors from the measured phase shifts (dm,n measure) and from the theoretical phase shifts (dm,n theoretical) of the sensor.

Abstract: A satellite-based positioning receiver includes processing channels, each processing channel being associated with a respective satellite from among N satellites, and an extended Kalman filter for performing a vector tracking for the set of satellites using signals received from the satellites. The extended Kalman filter performs a resetting on the basis of the phase error and code error received directly from the phase and code discriminators, of each channel, and the receiver is configured for calculating the code-wise and carrier-wise control signals for the code phase and carrier phase numerically-controlled oscillators, on the basis of data provided by the extended Kalman filter, for each channel.
