摘要

一般导航系统单点定位精度只有15 m左右

不能满足某些要求定位精度较高的场合

差分定位能很好的解决定位精度不高的问题.本文在差分GPS的基础上

提出和构建了基于北斗/GPS的组合伪距差分系统

通过该系统产生的伪距改正数能显著的提高用户的定位精度.同时

由于RTCM2.X格式没有定义北斗系统的伪距差分电文格式

本文提出一种改进的RTCM差分电文使其适用于北斗系统用户

以便于北斗用户使用此数据传输协议进行差分定位.

Abstract

In general

the positioning accuracy of single point navigation system is only about 15m

It cant satisfy some fields of precision positon

Differential positioning can be a good solution to the problem of low positioning accuracy.In this paper

On the basis of differential GPS

the BDS/GPS combined pseudorange differential system was designed

the users positioning accuracy can be significantly improved by pseudorange correction generated by the scheme.At the same time

duing to the Beidou system of pseudo range differential message format isnt defined int the RTCM2.X format

this paper proposes an improved RTCM differential message format to make it applicable to the user of the Beidou system

so as to facilitate the Beidou user to use this data transmission protocol for differential positioning
