介绍了目前无人驾驶飞机（无人机）的几种定位和导航方法，提出了一种新的无人机导航系统：ＧＰＳ导航系统；论述了该系统的总体方案，分析了其关键技术；设计并实现了系统的硬件和软件；给出了试验结果。该系统可自主导航，也可用遥控系统辅助导航。它可用遥测系统监测飞行，在屏幕地图上显示预定航线和飞行航迹。它可用单个ＧＰＳ接收机导航，也可利用遥控信道进行ＧＰＳ差分。这是一种应用前景很好的无人机导航系统。
This paper introduces several positioning and navigation methods of UAV (UAV), proposes a new UAV navigation system: GPS navigation system, discusses the overall scheme of the system, analyzes its key technologies, Design and implementation of the system hardware and software; give the test results. The system can be autonomous navigation, remote navigation system can also be used to assist navigation. It monitors the flight using a telemetry system and displays the planned route and flight path on the screen map. It can use a single GPS receiver navigation, remote control channel can also be used for GPS differential. This is a promising UAV navigation system.
