1. An unmanned aerial vehicle comprising:

  • a frame;

    an operations control to control operation of the unmanned aerial vehicle;

    a calibration control to initiate automatic calibration of the unmanned aerial vehicle by a hover mode for maintaining the unmanned aerial vehicle at hover position, and a calibration rotation sequence for rotating the unmanned aerial vehicle around at least one axis of the frame;

    flight control and navigation control for controlling motion of the unmanned aerial vehicle to implement the hover mode and the calibration rotation sequence;

    sensors to obtain measurement data during the calibration rotation sequence, wherein the sensors include at least one magnetic sensor for calibration;

    a calibration calculator to calculate calibration parameters using the measurement data obtained during the calibration rotation sequence.
