Problems solved by technology

[0004] In order to solve the problem that the existing technology usually uses GPS positioning method to obtain the flight parameters of the target aircraft, the positioning accuracy of the system is not high, and the measurement of the flight parameters is not accurate. Therefore, this positioning method cannot be used as the main way to obtain the parameters of the unmanned aerial vehicle. The environment is relatively harsh, such as ducts, valleys, high mountains with bad weather, etc. In these areas, GPS or similar signals cannot be obtained, so this method of testing aircraft parameters is completely inapplicable. At the same time, in flight parameter measurement In the case of inaccuracy, the flight attitude of the target aircraft cannot be accurately controlled. The present invention provides a target characteristic measurement system for the target aircraft. The measurement system can not only accurately obtain the flight parameters of the target aircraft in real time, but also accurately control the The flight attitude of the target aircraft, so as to complete the flight mission of the ground server
