Anti-multipath Technology for GNSS Receivers

This paper analyses the characteristics of multipath signal and the effect on GNSS(Global Navigation Satellite System) receiver peudo range measurement and carrier phase measurement,compares the mulipath suppression methods of GNSS receiver from two aspects of anti-multipath antenna and baseband signal processing,and points out that by adopting both antenna technology and baseband signal processing technology at the same time the good suppression result can be achieved for the high-precision GNSS receiver.
