Abstract

The invention relates to GPS and GLONASS satellite positioning receivers. A
novel receiver architecture is provided for receiving signals from and calculating a position using both GPS satellites and GLONASS satellites. Said architecture comprises a radio reception chain with an antenna (10), frequency conversion circuits (18), an ultra-high-rate analog-to-digital converter (38) for the GLONASS channel, and a signal processing circuit with a plurality of service-integrated channels for receiving both GPS and GLONASS signals. Said circuit (40) uses a programmable pseudo-random code generator and a phase servo loop using a local oscillator to produce a local translated carrier frequency. The oscillator is controlled in such a way that a starting frequency is set for satellite signal acquisition. The resulting receiver avoids dependence on one or other of the satellite networks as one network may be used should the other fail.
