satellite constellation

In order to determine relative positions between satellites and the attitudes of satellite of formation constellation, like-GPS carrier phase was added in based on former study of states determination combining with carrier phase differential GPS ( CDGPS) and like-GPS ranging code.

为了确定编队星座的星间相对位置和卫星姿态，在原有联合GPS差分和类GPS伪距进行状态确定的研究基础上，进一步加入了类GPS载波差分信息。

Getting the apriority of relative positions between satellites and attitudes of satellite by using pseudo positioning and intra-CDGPS, the entire states of formation constellation have been resolved by Bayes Least Square.

先由GPS伪距单点定位、GPS星内差分定姿获得卫星间相对位置、卫星姿态的先验信息，再采用Bayes最小二乘进行编队星座状态整体确定。

The orbit of the satellite constellation for local navigation system is discussed.

讨论了区域卫星导航系统卫星星座设计中所用卫星轨道类型.
