| 摘 要： | 导航卫星星座自主定轨技术是我国新一代卫星导航系统的关键技术之一.但是仅仅依靠星间相互测距定轨会因缺少地面基准而出现基准秩亏现象.针对这个问题,提出利用少量地面发射源随机工作的方式提供地面基准,将星间测距和地面发射源信息融合起来进行星座整网定轨,进一步提高定轨精度.最后利用仿真实验对该方法的合理有效性进行了验证.

| Abstract: | The autonomous orbit determination of navigation constellation is one of the key techniques of the Compass Navigation Satellite System(CNSS).There,howerver,is a deficiency problem of the datum mark when only intersatelite measurements of range is used.To solve this problem,this paper presents a new method that a few ground-based radio emitters should work randomly to offer the benchmark,and the constellation satellites should estimate their position and velocity for the whole network,based on the fusion of ... |
