The invention discloses an unmanned aerial vehicle navigation verification system based on dead reckoning, and belongs to the technical field of unmanned aerial vehicle navigation verification. The problem that existing flight verification has positioning errors is solved, the flight route is planned through the route planning module, and the central controller drives the unmanned aerial vehicle to fly according to the preset route; using a dead reckoning module to determine the coordinate of the current position of the unmanned aerial vehicle, a track parameter value and a motion direction, and reckoning the coordinate of a second calibration point when the unmanned aerial vehicle reaches the first calibration point to the second calibration point; a data calibration module is used for calibrating whether the current position parameter value of the unmanned aerial vehicle meets a preset calibration condition or not, if not, an instruction is sent to a central controller through an instruction correction module, and the coordinates of the current position of the unmanned aerial vehicle are corrected into the coordinates of a second calibration point; therefore, the defect of GPS failure or positioning error in the existing flight verification work is avoided, and the dead reckoning technology is added to ensure the accuracy of the navigation system and the flight verification work.

    本发明公开了一种基于航位数据推算的无人机航行校验系统,属于无人机航行校验技术领域。本发明解决了现有飞行校验具有定位误差的问题,通过航线规划模块规划出飞行航线,中央控制器驱使无人机按预定航线飞行;利用航位推算模块确定无人机当前位置的坐标、轨迹参数值和运动方向,并在无人机到达第一校准点至第二校准点时,推算出第二校准点的坐标;通过数据校准模块校准无人机当前位置参数值是否满足预设的校准条件,若不满足,则通过修正指令模块向中央控制器发出指令,将无人机当前位置的坐标修正为第二校准点的坐标;由此避免现有飞行校验工作中GPS出现失效或定位误差所具有弊端,增设航位推算技术保证导航系统与飞行校验工作的精准度。
