Abstract
A receiver for determining position based on GPS satellites and GLONASS satellites. The receiver architecture includes a radio reception chain with an antenna, frequency conversion circuits, an analogue/digital converter operating at very high rate for the GLONASS pathway, and a signal processing circuit with several general-use channels capable of receiving both GPS signals and GLONASS signals. This circuit uses a programmable pseudo-random code generator and a phase servocontrol loop which uses a local oscillator to produce a local transposed carrier frequency; this oscillator is controlled in such a way as to be able to impose a start frequency for the acquisition of a satellite signal.
