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.

Abstract: The field of the invention is that of the reception of a radionavigation signal originating from a satellite positioning system such as the GPS system. The present invention concerns a method for calculating correlations between a first sequence and a second sequence, said first sequence and said second sequence having a duration DCode, the first sequence being extracted from a digital signal comprising a code, said code comprising elementary time divisions, called chips, of mean duration Dchip, said chips being synchronized with pulses delivered by an NCO oscillator at the mean frequency 2/Dchip, the second sequence resulting from a sampling at a frequency Fe of an analog signal, the frequency Fe being greater than 2/Dchip. According to the invention, the method comprises a step of aggregating samples of the second sequence, over consecutive integration intervals of duration equal on average to Dchip/2, starting at each pulse of the NCO oscillator, so as to determine results of elementary aggregates.

Abstract: Described is a device for receiving radio-navigation signals by satellite, said received signals being transmitted at a carrier frequency. The device includes at least means for generating a local signal at a local frequency and a tracking device including a feedback loop called carrier loop for phase-locking the local frequency on the carrier frequency. The loop includes a hardware portion and a software portion. The software portion performs the functions of discrimination of the phase of the correlated signal and filtering of said phase. The software portion also includes correlation functions mainly dependent on the linear variation coefficients between the local phases φlocal delivered after each basic computation cycle. The device makes it possible to increase the loop band and the dynamic stability without changing the pre-detection band and the workload of the software.
