| 摘要: |
| 全球卫星导航系统在自主导航工作模式下，为了保持星座系统的稳定，保证系统的完好性，需要对故障卫星进行及时可靠的隔离。因此提出一种基于星间链路的全球卫星导航系统(GNSS)自主完好性隔离算法，分析全球卫星导航系统故障判别方式，设计了基于星间链路的故障隔离流程，提出了基于星间测距误差和判别的故障检测及隔离算法。仿真结果表明，基于星间链路的GNSS自主完好性隔离算法，可以有效隔离故障卫星，保持星座自主导航精度，并且算法实现复杂度较小，易于工程实 现。 |

| Abstract: |
| Under GNSS autonomous navigation mode, in order to keep constellation stabilization and integrity, failure satellites must be separated in time. A GNSS autonomous navigation integrity separation technique was developed, and satellite failure judgment method was analyzed. Satellite failure separation procedures were designed, and then a failure check and separation technique was presented. Simulation of this technique suggests that it ensures services precision by effectively separating failure satellites among autonomous navigation constellation. Furthermore, this technique is not very complex and easy for engineering. |
