| 摘 要： | 针对NASA的ST-3中自主编队飞行的双星星座，研究在无GPS信号覆盖区域，利用星载类GPS的伪距和载波观测数据自主确定双星星座之间相对位置与钟差的问题。文中首先给出了系统的数学模型；然后研究利用卫星姿态机动提供的几何信息，进行单差整周模糊度初始化的问题，讨论了最优化的卫星姿态机动方案；最后给出了仿真协方差分析结果。

| Abstract: | We studied the relative states autonomous determination of two satellites formation of the Space Technology 3,that is proposed by NASA,using the data of pseudorange and phase of like-GPS onboard when the signal of GPS can not been received.Firstly,the system model was built.Secondly,the single different phase bias was initialized with more epochs of pseudorange and phase observations during the relative attitude changed between the two satellites and the optimal initializing projection was investigated.Lastly,the result of simulation/covariance analysis was given. |
