区域卫星定位系统的星座设计
CONSTELLATION DESIGN FOR REGIONAL SATELLITE POSITIONING SYSTEM
-
摘要: 星座方案选择对卫星定位系统的性能具有很大影响,它应提供多重覆盖并满足一定的几何关系。该文首先针对卫星覆盖特性和DOP因子进行了阐述,基于所得结果,对区域定位星座进行了研究,并利用GPS的参考数据,对所给定位星座的定位性能进行了初步估算。最后给出了结论。Abstract: Constellation design has great influence on the performance of satellite positioning system, the constellation should provide multi-coverage and satisfy certain geometry. First, this paper presents coverage property of satellites and DOP factors, based upon these, researches for regional satellite positioning system and relevant estimates of positioning performance are provided. Finally, the application of and some questions about regional positioning constellation are explored, and conclusion is also given.
