Segments based on the distance and relative position of the vector dot product UAV flight segment switching method

The present invention discloses a segment based on the distance and relative position of the vector dot product of the UAV flight segment switching method. UAV switching to implement the entire segment flight routes. The flight control computer in real time to be calculated flying distance and the lateral offset distance segments obtained at the moment. When the GPS signal is normally full, using the method of switching segment based on the distance segment. When GPS signal is invalid, does not perform switching leg. After the GPS signal is restored, and the current position is calculated according to UAV segment from the point / point the relative position vector dot product, determined conditions for forming a composite with the segment that has been calculated from the UAV all of the above flight segment of the right switch.
