摘　　要：本文以自行研制的GPS接收机为基础,在分析差分GPS接收机定位原理及解调RTCMSC-104电文的基础上,提出了完整的差分GPS接收机方案,给出了算法流程图并予以实现。基于X60差分基准站、SuperstarⅡ、MATLAB完成实验平台搭建,最终实验结果表明,所研制的DGPS接收机定位精度在1m以内,充分验证了算法的正确性,为进一步研究提供了基础。Based on self-developed GPS receivers, in this paper we put forward a complete program of differential GPS receivers and its flow chart of algorithm, in which we fully work out the positioning prineiple of differential GPS receiver and demodulation of RTCM SC-104 message. Then we conducted the related＇experiment with the platform, which comprised of X60 differential base station, SuperstarⅡ and MATLAB. The result from the experiment is perfectly consistent with my algorithm that positioning accuracy of designed DGPS receiver is within 1m, and provides us foundation for further research.
