Claim 12:
13. A launching device, comprising:
an acquisition module for obtaining the geomagnetic triaxial data at a current moment at regular intervals according to the preset heartbeat time;
a first calculation module for calculating a corrected geomagnetic triaxial data according to the geomagnetic triaxial data at the current moment;
a second calculation module for calculating an angle value according to the corrected geomagnetic triaxial data and storing the angle value in a pre-established system data set;
a module for obtaining an updated system data set by using a Fourier transform algorithm on all of the angle values in the system data set;
a third calculation module for calculating an angle difference of the updated system data set accumulated in a preset time period;
a launch module used for controlling the UAV dispenser to execute the launch action when the angle difference value is greater than a preset angle value.
