摘要
基于北斗双星定位系统对双星定向技术进行了深入研究。建立了详细的观测误差模型,该模型考虑了接收机钟差对整周模糊度求解和定向结果的影响,并用旋转基线法实现了整周模糊度求解。完成了双星定向试验,试验结果表明,当基线长度为O.827m时,采用100秒的观测数据,双星定向精度优于0.03°。从而证明北斗双星定位系统具有快速、高精度定向的能力。
This paper makes an in-depth study of orientation determining with two Geostationary statellites base on the Beidou Positioning System. An accurate model of observation is established. The model considers the receiver' s clock error which influence the ambiguity resolution and the result of orientation. A series test was conducted in this paper with a 0. 827m baseline and 100s observation interval. The results showed that the precision of orientation determining with the Beidou Positioning system can excel 0.03°. It is proved that the Beidou Positioning system has an ability of orientation determining which can be accomplished quickly and accurately.
