| 摘 要： | 对北斗精密单点定位的观测残差进行了系统全面的分析;通过对一站多天、多站一天解的观测残差、天线相位中心偏差对观测残差的影响以及观测残差历元间的关系进行实验分析。结果表明,北斗GEO卫星的伪距和相位的无电离层组合观测残差存在着系统偏差,这一系统偏差与测站的观测环境无关;伪距的无电离层组合观测残差的系统偏差具有常数特性;相位的无电离层组合观测残差的系统偏差与天线相位中心偏差有关。

| Abstract: | The systematic analysis of the observation residual error of BDS PPP is carried out.Through station days and multi station a day of BDS PPP observation residuals analysis,it is concluded that the GEO satellite pseudo range and phase observation residuals have a systematic bias.The systematic bias is not related to the observation environment of the station.The pseudo range residual is constant and the phase is related to the deviation of the antenna phase center. |

| Keywords: | BeiDou precise point positioning pseudo range phase residual |
