摘　　要：随着我国BD-3系统建设的有序推进,地面站接收机测量性能成为影响导航系统服务性能的重要因素之一。本文针对地面站接收机及天线实际安装情况,提出了一种短/超短基线条件下接收机伪距测量一致性评估方法,解决了实际安装条件下不同型号接收机伪距测量一致性评估问题。以某地面站实测数据为例,对A、B、C三种不同型号接收机数据进行处理,得到相应结论,为接收机测距性能优化升级提出参考。With the development of BD-3 construction in China,the measurement performance of receiver has become one of the important factors affecting its application.According to the actual installation of the ground station receiver and antenna,this paper proposes a method of pseudorange measurement consistency evaluation under the condition of short/ultra short baseline,which solves the problem of different types of receiver pseudorange measurement consistency evaluation under the actual installation condition.Taking the measured data of a ground station as an example,the data of three different types of receivers,A,B and C,are processed,and the corresponding conclusions are obtained,which provide suggestions for the optimization and upgrading of the receivers.
