摘要
无人机飞行控制技术越来越成熟,其应用领域也越来越广阔。当前无人机定位导航完全依赖卫星导航系统,由于卫星导航信号格式公开,所以存在被欺骗的潜在威胁。针对这一问题基于大疆公司的DJI Mtrice100开源无人机平台和SAS6862A卫星中频信号采样与回放器,开展无人机航迹规划应用开发和欺骗方案设计。利用大疆DJI Mobile SDK的软件开发工具,研究了DJIWaypointMission库函数的使用方法,基于该库函数进行了航迹规划程序开发和试验验证。在航迹规划功能的基础上,基于卫星信号回放技术,提出了一种无人机航迹欺骗演示方案。揭示了无人机易受欺骗的潜在威胁,对无人机应用领域的安全防护有重要启示意义。
UAV flight control technology is more and more mature,and its application field is more and more broad.At pres⁃ent,UAV positioning and navigation are completely dependent on satellite navigation system.Due to the open format of satellite nav⁃igation signal,there is a potential threat of being deceived.Based on DJI Mtrice100 open source unmanned aerial vehicle platform and SAS6862A satellite if signal sampling and playback device,the UAV track planning application development and spoofs scheme design are carried out.By using DJI Mobile SDK software development tools,the method of DJIWaypointMission library function is studied,and the track planning program development and test verification are carried out based on the library function.Based on the function of track planning,a track spoofing demonstration scheme of UAV is proposed based on satellite signal play⁃back technology.This paper reveals the potential threat of UAV vulnerable to deception,which has important implications for the safety protection of UAV application field.
