摘要
传统的GPS定位技术在定位卫星信号接收差的场合工作不可靠,通过DR算法可将GPS信号进行修正和补充。介绍了DR算法的原理、GPS定位系统的系统架构、用户终端的组成、软件流程以及整个系统的功能。此系统较单一GPS定位系统性能更加可靠。
Traditional GPS positioning technique is unreliable as it works on the occasion of insufficient satellite signal, and it can be modified and complemented by DR arithmetic. This paper introduces the theory of DR arithmetic, the structure of GPS positioning system, the element of user＇s terminal and its software flow chart, and the functions of the entire system. This system works more reliably than single GPS positioning system does.
