| Abstract: | Abstract：Considering the built Beidou satellite navigation system , constellation performance and reconfiguration methods of satellite navigation system with satellite failure are studied.The service performance of navigation constellation under different failure modes is analyzed;then the optimization model of navigation constellation reconstruction configuration and the optimization design method of navigation constellation reconstruction configuration based on genetic algorithm are established.Maneuver strategy and maneuver model of the satellite are studied during the reconstruction of constellation configuration; finally, a specific failure situation is simulated, the maneuver scheme of reconstruction under this failure condition is given. |
