| 摘要: |
| 本文详细介绍了在无人机利用GPS导航半实物仿真系统中GPS仿真器的设计原理。通过分析GPS及GPS接收机的基本工作方式, WGS-84与各种坐标系的转换关系, 研制了GPS仿真器。它将由飞行仿真计算机得到的无人机位置信息转换成与之对应的GPS信号, 输入飞控计算机, 以实现GPS导航的仿真试验。 |

| Abstract: |
| The priniciple of GPS emulator, used in emulational GPS nevigation system for UAV has been described in detail in this paper. By analyzing the basic work manner for GPS and its receiver, the relationship between WGS-84 system and other coordinates, the GPS emulator is produced. It converts the location information obtained by UAV fly simulating computer into corresponding GPS signal, which is attained by the controlling computer in UAV. The experiments show that it is qualified in simulation. |
