| 摘要: |
| 首先针对小卫星星载GPS伪码测距, 基于星间差分消除/消弱误差, 并引入星座网形约束, 论述了星座模式下提高小卫星定位精度的一种整网数据处理方法, 并给出了一个算例。然后进一步论述了不依赖GPS的小卫星星座测控, 以及提高小卫星星座定位自主性问题的几点设想。 |

| Abstract: |
| In this paper, in order to improve the small satellite's positioning precision under constellation mode, we discuss a methed to deal with whole network datum of psecdocode measuring distance of GPS carried on the satellites, based on decreasing or eliminating error by difference between satellites and introducing the network restraint of constellation. After that, an actual example is given. Finally, we present several presumptions aiming at small satellite constellation's measurement and control, while not relying on GPS and raising the independence of small satellite constellation's positioning. |
