摘要
惯性仪表误差直接影响导航精度,很多情况下,为了能够取得更好的惯性测量系统误差标定结果,需要在机载动态的情况下实时地在线标定惯性器件的误差;基于此目的,利用PC机和两组RS-232串口通道作为基本的平台硬件,在Visual C++开发环境下开发了半物理仿真应用程序;仿真平台具备了基本的可视化操作界面、惯性测量系统仿真功能、数据传输功能以及标定解算功能;并且对安装方式的误差进行了标定仿真实验,并取得了较好的可实现性,为空中在线标定惯性系统误差提供了比较可靠的仿真实验平台。
The precision of navigation is decided on the error of inertia measuring system. In order to get the better demarcating result of inertia measuring system error, demarcating error parameter is very important in airborne condition. Be based upon this target, a semi--physical application has been exploited while using Visual C＋ ＋ as sofeware environment and using personal computers and RS-232 serial bus as hardware. This simulation platform is provided with view interface, inertia measuring system simulator, data transmitting function and error demarcating and calculation function. In addition, a installation error parameter demarcating simulation experiment is completed, and can get a rather good result. Gernarally, a credible method of demarcating error has been provided by this simulation platform.
