摘　　要：以三星编队星座为例 ,讨论利用高精度的星间伪距观测进行星间相对位置、姿态和时间参数确定的一些问题 ,包括 :坐标系、独立参数的选取和观测方程的建立 ,星座状态的转换 ,天线的安装和指向等 。In the case of the formation flying constellation, this paper discusses some problems about the determination of relative states, which includes the relative position, attitude and time between the formation flying satellites, by using precise pseudo ranging. The problems are the selection of coordinate system and independent state parameters, the setting of observation equations, conversion of constellations states, orientation and installing of antenna. Numerical simulation and analysis are made for an earth observation constellation.
