| 摘 要： | 给出了北斗卫星单系统和多系统融合非差精密定轨方法的基本原理和主要区别，并结合实测数据，对比分析了两种方法的定轨精度。结果表明，在一定观测条件下，两种方法定轨精度基本相当，GEO卫星三维定轨精度能达到1 m左右，IGSO和MEO卫星能达到0.2~0.3 m，3类卫星径向轨道精度优于10 cm。

| Abstract: | The principles of and differences between Beidou single-system and multi-system zero-difference precise orbit determination are presented. Their respective precision is compared based on real observation data. The results show that the precision of two methods is comparable in current conditions. The three-dimension orbit precision of GEO can reach about 1 m, and that of IGSO and MEO can reach 0.2-0.3 m. Their radial precision is better than 10 cm. |
