为深入挖掘利用导航系统各测量信息,提高系统导航精度,提出一种惯性基多信息在线后处理技术。通过对系统存储的历史信息进行在线后处理,实现系统实时导航性能的改善,并以其在捷联惯导系统初始对准中的应用为典型案例,展示了惯性基多信息后处理技术在实际工程中的应用效果。仿真结果表明,在线后处理技术可以充分挖掘已有信息价值,有效提高实时导航性能。
In order to excavate and utilize each measurement information of navigation system and improve the precision of system navigation, an online post-processing technique of inertial basis information is proposed. Through the online postprocessing of the historical information stored in the system, the real-time navigation performance of the system is improved. The application of SINS in the initial alignment is taken as an example to show that the inertial basis information processing Engineering application effect. The simulation results show that the online post-processing technology can fully tap the existing information value and effectively improve the real-time navigation performance.
