摘要: 全球卫星导航系统（GNSS）因具有覆盖范围广、使用成本低的特点而被广泛使用,但其多采用中、高轨道卫星,信号落地功率低,易受干扰,因此,为保证卫星导航系统的正常使用,需开展对导航干扰源的探测与定位研究.针对现有地面干扰源排查设备存在的定位精度低、机动性弱、定位时间长、干扰定位对测向环境依赖性高等问题.本文提出了一种基于无人飞行器的导航干扰源探测与定位系统设计与实现方法,通过在无人飞行器上搭载测向载荷,实现空中干扰源探测与定位,该系统具有作用距离远、覆盖区域大和机动性强等优点.Abstract: Global Navigation Satellite System is widely used because of its wide coverage and low cost. However, due to the use of MEO,IGSO and GEO satellites, the signal landing power is low and susceptible to interference. Therefore, to ensure the normal use of GNSS, it is necessary to carry out research on the detection and positioning of navigation interference sources. Aiming at the defects of low positioning accuracy, weak maneuverability, long positioning time, and high dependence on the environment, this paper proposes a navigation interference source detection and positioning system based on UAV. The design and implementation method is to realize the detection and positioning the navigation interference sources by carrying direction finding loads on unmanned aerial vehicles. The system has the advantages of long working distance, large coverage area and strong maneuverability.
