ABSTRACT:
The invention relates to a satellite position pinpointing receiver intended to carry out combined processing of a first received radio signal and a second received radio signal which differ in frequency. The receiver comprises: a first correlator circuit and a second correlator circuit receiving the first and second received signals respectively, each correlator having a carrier correlation channel, a code correlation channel and a code correlation channel integrator. The receiver furthermore includes: a central-carrier phase discriminator; a device, the respective local carriers for the carrier correlation channels, a code phase discriminator; and a numerically controlled oscillator, for each correlation channel. Applications: satellite radio navigation by GPS, Galileo, Glonass, etc.
