SINS/GPS组合导航仿真系统研究

Resarch on Simulation Software of SINS/GPS Integrated Navigation

SINS/GPS组合导航仿真系统的研究对于方案论证、系统设计以及工程研制等有着重要的意义。介绍了组合导航系统原理以及组合导航仿真系统的结构和原理,包括航迹仿真器、惯导仿真器、GPS仿真器及卡尔曼滤波器等。系统采用Visual C++6.0语言开发,效率高,可移植性强;采用OpenGL做实时动画显示,界面丰富,可观测性强。该系统讨论了仿真系统的功能设计和人机界面设计以及相关的核心算法等,最后在该系统下进行了仿真,取得了较好的效果。同时模块化设计使得该软件中的核心算法已成功移植应用于实际工程中。

The research on simulation software of SINS/GPS is very important to the conceptual definition, system design and development. In this paper, the principle and structure of the system are introduced, including flight trajectory simulator, INS simulator, GPS system simulator, Kalman filter and so on. The system is programmed with VisualC ＋＋ 6.0 ,which is highly efficient and easily transplanted. Some moving images displayed in this system are programmed with OpenGL, which has colourful interface and high observability. The function design, main - computer boundary design and some core algorithms are studied. The excellent simulation result about the system is given at last. And its modular programming concept can convert its core arithmetic into reality of the navigation system successfully.
