摘要
研究了 GPS在一类没有结构和力约束 ,但存在运动约束的多航天器系统中的应用。首先分析了GPS在该系统中应用的模式和方案 ,重点研究了相对 GPS(RGPS)导航和 GPS姿态确定的方法和算法。然后提出了 GPS在该系统中应用的总体结构和功能结构。最后对 GPS在该系统中应用的选星、滤波器设计、误差消除等问题进行了讨论。研究结果有助于 GPS在多航天器系统中应用的标准化。
The applications of GPS in a multi spacecraft system with kinematical restraint but no structural restraint and force action to each other are studied in this paper. First, the modes of GPS applied in this system are analyzed, and methods and algorithms of relative GPS navigation and GPS attitude determination are described. Then a general system construction and a functional architecture of GPS application in the system are presented. Finally, some related problems, including GPS satellite selection, filter design, error elimination, etc. about the applications of GPS in the system are discussed. The research work makes a contribution to the standardization of the application of GPS in the multi spacecraft system.
