| 摘 要： | 根据区域卫星导航系统星座结构的特点,针对GEO星、IGSO星存在的轨道机动问题,以及星座建设阶段存在可用导航卫星少于4颗的情况,给出了一种综合利用接收机自主完好性故障检测排除算法、三星定位方法、病态数据处理方法的解决策略,可以提高区域卫星导航系统在一般导航应用中的有效性和连续性。实际算例结果表明了所提方法的可行性。

| Abstract: | According to the characters of regional navigation satellite system,there are some problems that GEO and IGSO satellite may maneuver and less than 4 available navigation satellites could be used during its early building stage.We propose a type of navigation strategy which adopt Receiver Autonomous Integrity Monitoring faults detection,exclusion method and three stars positioning approach and ill conditioning of normal equation resolution to overcome these problems.Then the validation and continuity of navigation satellite system in ordinary application fields can be improved.By handling the actual data,the feasibility of these approaches is verified. |
