摘要: 我国的北斗卫星导航定位系统目前已经发射9颗“北斗”卫星,北斗区域卫星导航系统的基本系统已建设完成,正开展星地联调和测试评估工作,已经具备我国范围内的初步三维定位导航能力。本文研究了Beidou和GPS的时间系统/坐标系统的统一、卫星广播星历与卫星位置计算,以及二者的高精度定位算法,并实现了Beidou和GPS载波相位的数据融合和高精度联合定位,最后通过2011年9月29日的实测数据和处理结果证明了本文方法的正确性,同时为北斗二号系统的调试提供相关试验与结果。

Abstract: Currently, nine COMPASS satellites have been launched. Regional positioning system of COMPASS has been constructed. It can supply Chinese users with primary three-dimensional positioning. Mainly work of COMPASS is focused on tests and evaluations. This paper discusses conversion of time and coordinates between COMPASS and GPS, broadcasting ephemeris and calculation of satellite coordinates, and precise positioning with COMPASS and GPS. The united precise positioning with COMPASS and GPS is realized, and proved by test results of observations on Sept. 29, 2011. Our tests and results can supply reference to construction of COMPASS II system. Key words: Global Positioning System; Compass Satellite Navigation System; Fusion Positioning
