Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a multiband GNSS receiver of simple and economical construction.SOLUTION: This radio frequency receiver 40 for GNSS signals (GPS, Galileo, Glonass), composed of a single chip 45 and a small number of external components, has a group of independent signal paths 180a-180c each including a separate intermediate frequency stage and baseband down-converter 160. Each signal path is tuned to a specific intermediate frequency band by selection of external intermediate frequency filters 110a-110c. Conversion to an intermediate frequency involves a common local carrier generator 102.
