| 摘 要： | 区域卫星导航系统采用混合星座设计,GEO(地球同步轨道)卫星是系统的重要组成部分,其精密定轨技术也是导航系统的关键技术之一。GEO卫星的高轨特性致使地面跟踪基线长度有限,定轨几何条件不佳;其静地特性致使卫星轨道与钟差存在强相关特性,对于基于伪距的GEO卫星定轨模式,需要星地与站间时间同步技术的支持。因此,如何利用区域卫星导航系统的多种测量技术实现多模式、多层次的导航卫星精密定轨,是一项值得深入研究的课题。

| Abstract: | A mixed navigation constellation is employed in the regional satellite navigation system.The GEO(Geostationary Orbit) satellite plays a significant role in the system,and the POD(Precise Orbit Determination) is the key technology in the regional satellite navigation system.Therefore,how to employ several kinds of tracking techniques to achieve multi-mode and multi-level precise orbit determination for navigation satellites is worthy of in-depth study in regional satellite navigation system. Based on the fra... |
