摘要
针对GPS系统为美国军方控制的现状,研究了以我国已具备区域导航定位的能力的"北斗"卫星导航系统和无线数传电台为核心的无人机状态监控系统。系统以MSP430系列处理器为控制单元,利用UM220"北斗"导航接收机获取无人机的状态信息,通过无线数传电台EL805将机载信息发送至地面监控中心以及接收地面监控中心的控制指令,并利用虚拟仪器软件LabVIEW开发无人机监控平台,实现无人机飞行姿态的监控。引入范数的概念对"北斗"导航定位性能进行分析。实验测试表明,该系统运行稳定,人机交互界面良好,信息化程度较高。本研究对摆脱GPS,利用"北斗"实现无人机和通用航空飞机的导航和监控具有一定的参考价值。
Due to the status of Global Positioning System（GPS） system under the control of USA DoD, the Un manned Aerial Vehicle（UAV） monitoring system is studied, the core of which is China＇s Beidou satellite navi- gation system and wireless data transceiver. The MSP430 processor is selected as the control unit. The UM220 Beidou navigation receiver is used to acquire the UAV status information. The wireless data transceiver ELS05 is used to send onboard information to ground monitoring center and receive control command from ground control center. By using Laboratory Virtual Instrument Engineering Workbench（LabVIEW） software, the UAV status monitoring platform is developed to achieve the UAV flight status as well as the analysis of Beidou navigation po- sitioning performance. Experiment results show that the system can work stably, and is featured by good man-ma- chine interfaces, information and intellectualization. This study has some reference value for getting rid of GPS and taking advantage of Beidou to navigate UAV and general aviation aircraft.
