摘要
针对捷联惯导系统半实物仿真试验的时序同步问题展开研究。以某工程任务为背景，在充分考虑各系统之间的时间同步、接口通信传输延迟等问题的基础上，设计了捷联惯导系统半实物仿真试验方案。通过多次仿真试验表明。此方案很好地解决了捷联惯导系统半实物仿真试验的时序同步和接口通信问题，满足半实物仿真试验的实时性要求。
Time synchronization of hardware-in-the-loop simulation about SINS is discussed here. Based on a certain engineering task, the scheme of hardware-in-the-loop simulation about SINS was presented, after taking the problems of time synchronization among all the subsystems and time delay in interface communication into account in details. The results of the scheme show that the problems about time synchronization among all the subsystems and time delay existed in interface communication are solved very well and the scheme is feasibility for real-time.
