Satellite-based positioning receiver with correction of cross correlation errors

A satellite-based positioning receiver with correction of inter-satellite cross-correlation errors, comprising:

• a correlation channel Cii of order i per satellite received, with i=1, 2, . . . N, N being the number of satellites received (Sat1, Sat2, . . . SatN);
• each correlator channel Cii having:
• a carrier correlation path, in-phase and quadrature, between the signal received and two respective local quadrature carriers (sine, cosine) generated by an oscillator with digital control of carrier;
• a code correlation path based on the signals I, Q output by the in-phase and quadrature carrier correlation path, with the local codes of the satellite received, provided by a digital generator of local codes;
• and
• an integrator for providing, for each local code, signals Ic Qc at the output of the correlator channel Cii of the satellite received, c designating each of the local codes,
• wherein for each correlator channel Cii of the satellite received as many additional correlator channels Cix as additional satellites received with x=1, 2, . . . N and x different from i, and in that the local codes of the satellite received are correlated with the local codes of the other additional satellites Cix.
