摘要
针对真实捷联惯性导航系统难以进行重复工程实验问题,根据捷联式惯导系统特点,设计并实现了多功能捷联惯性导航仿真平台。针对不同运动载体的轨迹特点,平台实现了惯性器件信息、卫星接收机信息等多种传感器信息的仿真,并基于VC实现了载体模式选择、导航信息仿真、结果对比分析、信息多维显示等多种功能。系统采用Measurement Studio套件中的Graph3D控件实现了三维航迹的实时显示与对比。测试表明,仿真平台能够有效实现数据仿真、解算、显示、对比、分析等功能,可为相关导航系统算法的验证提供多种数据源,具有易维护、易扩展和高效率的特点。
It is very hard to repeat the experiments of engineering SINS （Strapdown Inertial Navigation System） without loss of information. According to the characteristics of SINS, a multi- function inertial navigation simulation platform is designed and realized. Information of IMUs ＆ GNSS receiver can be simulated properly based on the characteristics of different kinds of vehicle trajectory. The multi- function, such as carrier mode selection, navigation information simulation, comparative ＆ analysis of results, and multidimensional information display are implemented based on the Visual C ＋＋ software, and the three- dimensional track display and contrast is achieved in realtime using Measurement Studio Suite＇s Graph3 D control. Tests results indicated that the simulation platform has the function of data simulation, solving, display, compare and analysis, and it can provide the data for verifying the algorithms of navigation system. The efficient SINS simulation platform is with the features of easy implementation, easy expansion and high efficiency.
