在GPS伪距差分测量中，针对基准站和流动站之间接收机钟差的处理提出一种新的解决方法，该方法不需将接收机钟差作为未知参数来与流动站坐标参数一并求解，而是采取一种预先处理的方式。通过该方法，基准站和流动站只需同步观测3颗以上相同卫星便可求解流动站的位置坐标，不仅减少方程中未知数的数量，减轻计算和存储的负担，而且当流动站处于遮挡严重或者卫星信号较差的情况下，相比之前更有利于求解流动站的位置坐标。

According to the GPS pseudo range difference measurements ,a new method is proposed about the receiver clock error processing between the base station and mobile station ,which does not need to treat the receiver clock error as unknow n parameters and to solve the unknow n coordinate parameters of mobile station in the way of pre‐processing . The parameters of mobile station can be solved with this method by using three more of the same simultaneous observation satellites ,w hich not only reduces the number of unknow n parameters in the equation ,reduces the burden of computing and storage ,but w hen the mobile station is in serious occluded or satellite signal poor situation ,it is easy to solve the coordinate of the position of the mobile station .
