英文摘要：

In order to make full use of the global navigation satellite system resources,to maximize the advantages of the BeiDou satellite navigation system and provide high precision,high reliability and stability and better service to the users,the performance of grid pseudo-range differential positioning of BDS/GPS/GLONASS three system was analyzed.This paper introduced the principle of this method and analyzed the vehicle test.The results showed that the positioning accuracy and solution rate of grid pseudorange differential positioning of three system was higher than other scheme,the number of visible satellites was greatly improved,and the reliability and stability were better.
