Abstract
A navigation receiver processes signals transmitted by global navigation satellites and received by a set of antenna units. Each antenna unit is connected to a separate input port of an antenna multiplexer switch. Satellite signals received from each antenna unit are consecutively switched to the input of a common radiofrequency processing module. A common signal correlator generates a common in-phase correlation signal from the satellite signals received from all the antenna units. The common in-phase correlation signal is processed by a data processing module to demodulate information symbols from the received satellite signals. The common in-phase correlation signal is also processed by phase-lock loops and delay-lock loops to generate carrier phases and code delays from the received satellite signals. Embodiments are described in which, along with the common in-phase correlation signal, common functional blocks or hardware are used to process the satellite signals received from all the antenna units.
