基于Simulink的SINS/GPS组合导航系统仿真

Simulation for SINS/GPS Integrated Navigation System Based on Simulink

针对采用传统语言编程方法实现数学仿真存在效率低、可视性差等缺点,基于Matlab/Simulink动态仿真环境,使用模块图和编制S-函数相结合的方法,设计了SINS/GPS组合导航的仿真模型。SINS和GPS采用位置、速度综合模式,使用Kalman滤波技术。结果表明使用该仿真模型进行系统仿真简便、迅捷、可视性好、数据分析能力强,且其结构简单、参数修改方便,具有很大的工程使用价值和推广意义。

The conventional language programming method is inefficient and has poor visualization in constructing mathematical simulation system.In view of these disadvantages,a new type of mathematical simulation model for SINS/GPS integrated navigation system is designed by using simulink modules and S-function based on the Matlab/Simulink.SINS and GPS adopt position and speed integrating mode using Kalaman filter,the result shows that this simulation is convenient,speedy,visualized and has strong data-analyzing capability;moreover it is simple and easy to modify parameters,so it has high engineering practice and promotion significance.
