【摘要】 本文开展了BDS、GPS及BDS/GPS双系统相对定位精度分析,利用双差残差评定观测值精度,分析表明BDS卫星的伪距和相位测量精度与GPS相当。并基于不同的卫星截至高度角进行了BDS、GSP、BDS/GPS模糊度固定率和相对定位精度分析,结果表明BDS和GPS联合定位可以有效改善BDS和GPS的定位精度,进一步证实了BDS/GPS双系统组合定位的高精度与可靠性。更多还原

【Abstract】 In this paper, the relative positioning accuracy of BDS, GPS and BDS/GPS dual system is analyzed. The accuracy of the observed values is evaluated by the double difference residuals. The analysis shows that the accuracy of BDS satellite pseudorange and ph ase measurement is equal to that of GPS. And the elevation angle of BDS, GSP, BDS/GPS ambiguity fixing rate and relative positioning precision analysis based on different satellites, the results showed that BDS and GPS combined positioning can effectively improve the positioning accuracy of GPS and BDS, further confirmed the accuracy and reliability of BDS/GPS dual system positioning.更多还原
