| 摘 要： | 为解决无人机GPS自主导航系统的地面实验环境问题，结合某型无人机GPS自主导航系统的开发，首先提出了机载GPS信号模拟器的概念；其次，探讨了机载GPS信号模拟器的基本组成以及各组成部分的工作原理和实现方法，采用四元素法来实现无人机姿态角的求解，用迭代的方法来进行大地参心坐标系和WGS-84坐标系之间的转换；再次，在BORLANDC＋＋3．1编译环境下采用C语言编制了机载GPS信号模拟器仿真软件和地面监控软件；最后，设计了基于GPS自主导航的半实物仿真实验方案并对某型无人机进行了仿真实验，取得了良好的实验效果。

| Abstract: | To found the GPS autonomous navigation simulation system of UAV,with the development of certain UAV autonomous navigation system based on GPS,first,the paper advances the concept of dynamic GPS emulator.Secondly,the frame of dynamic GPS emulator,the principle and realization method of all components have been described in detail,getting the aircraft flight parameters through four-elements algorithm and switching the coordinate between the Terrestrial Geodetic coordinate system and WGS-84 coordinate system with iterative algorithm.Thirdly,in Borland C++ compiler,the dynamic GPS emulator software and the ground monitor software have been designed.In the end,the semi-physical simulation experiment system based on GPS has been designed and used in the simulation of certain UAV with favorable effect. |
