Abstract：SA(Selective Availability)policy is disabled,the application of SPS(Standard Positioning Service)location ser-vice has been significantly developed. Aiming at the problem that the positioning result is shifted when SPS(Standard Positioning Service)is positioned,a method of receiving satellite information(elevation angle and direction angle)using GPS receiver is pro-posed to reduce the offset error.And the simulation results are compared with the index of the angle and distance of the experimental results,and the direction and the offset of the offset are predicted and improved,and the positioning accuracy of the SPS is im-proved.
