Satellite-based positioning receiver, comprising processing channels, each associated with a respective satellite from among N satellites, an extended Kalman filter adapted for performing a vector tracking for the set of satellites using signals received from the N satellites, in which: the said extended Kalman filter is adapted for performing a resetting on the basis of the phase error and code error received directly from the phase and code discriminators, of each channel, and in that the receiver comprises first means for calculating the code-wise and carrier-wise control signals for the said code phase and carrier phase numerically-controlled oscillators, on the basis of data provided by the said extended Kalman filter, for each channel.
