Simulation Study on Strapdown Inertial Navigaton System of UUV Based on Track Module Design

基于仿真系统要求,文章提出了系统功能模型,并详细推导了一种水下航行数据产生方法。该方法可以给出一套求解各种导航参数的解析公式,并能导出捷联惯导系统的原始输入数据;仿真实验以生成轨迹为基准,对系统进行仿真,根据其输出参数与轨迹仿真器对应参数的吻合程度来检验仿真程序的合理性。仿真结果符合检验标准,基于模块设计的仿真方法行之有效。

The function model of simulation system is introduced based on the simulation system requirement,and a comparatively precise and analytic track creating method is put forward.It can present a set of analytic formulas which are used to calculate navigation parameters,and the original input information of SINS is deduced on basis of this formulas.Simulation is made on the benchmark of track,through the tally degree between track parameters and correlative simulation parameters,we test the validity of simulation.The result is up to the standard,and the simulation method based on module design is effective.
