| 摘 要： | 分析了捷联惯导系统误差来源,构建了由器件误差、安装误差及初始条件误差共31个误差源组成的捷联惯导系统误差模型.为提高代码重用率,在VC环境下建立仿真平台,并通过调用Matlab引擎,用图形化方式量化了各种误差源对导航结果的影响.结果表明,设计的仿真平台能够提供高效的误差分析手段,可为捷联惯导系统的误差分配和器件选型提供参考.

| Abstract: | The error sources of strap-down inertial navigation system(SINS) is analyzed,and on the base,the model which is composed of device error,fixing error and initial condition error,totally thirty-one error sources is designed.In order to improve code reuse rate,this mode is designed in the VC environment,by calling Matlab engine,the influence of various error sources on the output results of navigation is quantified by graphics.All results show that effective analysis method could be provided by this simulatio... |
