摘　　要：舰艇惯性导航系统的工作性能,尤其是导航误差,与舰艇的运动有关。为便于开展舰艇运动状态对惯性导航系统误差影响的研究,设计了一套基于舰艇运动状态为激励输入的舰艇惯性导航系统仿真软件。对仿真系统的结构组成、舰艇运动状态仿真的架构原理和舰艇运动状态信息至惯导敏感信息的转换流程进行了设计,详细介绍了仿真软件的功能组成和设计使用,分析可知,在给定仿真参数的情况下,可以输出导航参数及导航误差。设计的仿真软件对研究受舰艇运动状态影响的惯导系统动态性能误差具有参考价值。The performance of naval vessel inertial navigation systems,particularly in terms of navigation errors,is intricately linked to vessel motion.To facilitate the examination of how vessel motion influences inertial navigation systems errors,a simulation software is developed,using vessel motion status as input to excite the inertial navigation systems.The simulation systems structural composition,the architectural principles governing vessel motion status simulation,and the process of converting vessel motion status information into sensitive data for the inertial navigation systems are designed.Additionally,the functional composition and the practical application of the simulation software is elaborated in detail.It shows that,when provided with specific simulation parameters,the navigation parameters and associated errors can be output.Consequently,the developed simulation software holds value for investigating the dynamic performance errors of inertial navigation systems influenced by vessel motion status.
