无人驾驶飞机GPS导航系统的设计与实现

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。

Design and Implementation of a Navigation System for Pilotless Aircraft Using GPS

We foresaw China's need for a new kind of navigation system for pilotless aircraft using GPS(Global Positioning System), which has not only autonomous navigation capability, but also can achieve navigation aided by telemetering and telecontrol systems. In the absence of relatively detailed information about such a new system noW already used abroad , we present our design of it. Fig. 1 shows the schematic of our design: Fie. 1(a) for pilotless aircraft and Fis. 1(b) for ground station. The features of our design are:(1) It can run in single GPS receiver mode or in the differential GPS mode by means of available telecontrol channel.(2) It can supervise flying with telemetering system and display both planned and actual flight path on digital map and the pilotless aircraft' s distance, azimuth, height, velocity,course, etc.(3) When the pilotless aircraft in autonomous navigation, its control signals are automatically obtained through airborne microcomputer's determination of deviation of actual flight path from planned one.Our design is preliminarily confirmed as being successful by flight tests.
