摘　　要：针对高轨道飞行器的定轨问题开展研究,对导航星的空间可见性和信号可用性进行了分析,针对单一系统无法满足定轨需求,提出了多系统互操作的组合定位方法:一方面可以有效增加可见卫星数量,改善卫星几何结构图形,提高卫星定位精度;另一方面,填补单一系统存在覆盖盲区问题,扩大了系统的应用领域。同时,给出了多系统数据融合算法解决GNSS进行高轨飞行器定位的相关问题,最后,通过仿真证明分析模型、方法的可行性。Positioning of high earth vehicle by using GNSS is researched.A single satellite navigation system such as GPS can not get satisfactory results in most of the application area.The combined GNSS position system,on the one hand,increases the number of visible satellites and improves the precision of position and navigation;on the other hand,it can cover the blank areas that a existed single system can not do.In this paper,the GPS,GLONASS,GALILEO combined system is described in general and the integration of GNSS is implemented,and the GNSS combined pseudo-range positioning models are formulated in great detail.At last,the feasibility of the analysis model and method is proven by simulation.
