| 摘 要： | 提出了一种适用于飞船交会对接的GPS差分相对定位导航方案。在远程导引段，采用坐标差分相对定位；在自动寻的段，采用双差载波相位平滑伪距技术；在接近和逼近段，采用双差载波相位浮点解相对定位，求得模糊度后，可采用双差载波相位整数解获得很高的定位精度。仿真试验证明，该方案切实可行。

| Abstract: | A relative navigation scheme is proposed for spacecraft rendezvous. Coordinate differential navigation is used when the distance between two spacecrafts is very long. In the course of automatic homing, the method of double-differencial carrier phase smoothing is applied. When the two spacecrafts are close, the float solution is very efficient. After the integer ambiguity acquisition, the integer solution can have a very high precision. A simulation proved this scheme is feasible. |
