CONCURRENT MULTI SYSTEM SATELLITE NAVIGATION RECEIVER WITH REAL SIGNALING OUTPUT

摘要

A GNSS receiver (300) includes at least one GNSS antenna (206) configured to receive input signaling from at least a first GNSS source and a second GNSS source; an I/Q mixer (202) coupled to the at least one GNSS antenna and configured to process the input signaling to obtain complex intermediate signaling; a first complex filter (310) coupled to the I/Q mixer and configured to filter the complex intermediate signaling with respect to a first frequency range to obtain first real output signaling; a second complex filter (312) coupled to the I/Q mixer and configured to filter the complex intermediate signaling with respect to a second frequency range to obtain second real output signaling; and a signal combiner (320) coupled to the first and second complex filters and configured to combine the first real output signaling and the second real output signaling.
