摘要
分析了多径信号特性及其对全球导航卫星系统(GNSS)接收机伪距测量和载波相位测量的影响,从抗多径天线和基带信号处理两方面对GNSS接收机的各种多径抑制方法进行了比较与分析,指出高精度GNSS接收机会同时采用抗多径天线和基带信号处理以达到较好的多径误差抑制效果。
This paper analyses the characteristics of muhipath 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 - muhipath 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 resuh can be achieved for the high - precision GNSS receiver.
