METHOD FOR THE CORRECTION, UPON RECEPTION IN A MOVING OBJECT, OF FAULTS AFFECTING THE TRANSMISSION OF BINARY OFFSET CARRIER RADIONAVIGATION SIGNALS
First Claim
1. Method for the correction, upon reception in a moving object, of faults affecting the transmission of binary offset carrier radionavigation signals, the signals originating from several reference position sources, comprising the steps of:
- demodulating each component of the signal received by a conventional BPSK demodulation method, compensating for a phase differential of the two signals, source by source, and carrying out coherent tracking by summing the complex outputs of the demodulation processing.

Abstract
A subject of the present invention is a method for the correction, upon reception in a moving object, of faults affecting the transmission of binary offset carrier radionavigation signals, enabling this correction to be carried out in a simple and reliable manner. The method of the invention is characterized in that each component of the signal received by a conventional BPSK demodulation method is demodulated, in that the phase differential of the two signals is compensated for, source by source, and in that a coherent tracking is carried out by summing the complex outputs of the demodulation processing.
