Key technologies of UAV calibration flight

Against the problems in precision appraisal of TT C (Telemetry, Tracking, and Command) equipment recently, it proposed to complete the task of calibration flight with UAV (Unmanned Aerial Vehicle) technology. This paper describes the basic system structure and working principle of the UAV calibration flight, focuses on key technical issues of the system, and finally leads to the accuracy identification results of UAV calibration flight. To perform precision appraisal task of calibration flight using UAV, has the advantages of the flexible task time, convenient implementation organization, flexible airway design and easy security work. UAV calibration flight system has a positive significance to the construction of equipment precision appraisal test system of aerospace TT&C system.
