Remote control signal cross positioning method based on vehicle-mounted system

The invention belongs to the technical field of vehicle-mounted system unmanned aerial vehicle pilot position acquisition, and particularly relates to a vehicle-mounted system-based remote control signal cross positioning method, which comprises the following steps of: establishing a reference coordinate system by taking the position of a group leader vehicle as an original point, taking the due north as a Y axis and taking the due east as an X axis; receiving a north angle, a heeling angle and a trim angle of the vehicle, and correcting a relative direction of a remote controller signal reported by radio detection equipment of the vehicle to obtain a linear equation of the remote controller signal of the vehicle under the reference coordinate system; receiving positioning information and remote controller signal absolute azimuth information reported by the group member car, and performing coordinate transformation according to longitude and latitude heights of the group member car to obtain a group member ca
