Embodiment 1

[0089] In order to verify the feasibility and beneficial effect of a track generation method that reduces the magnetic interference of the fixed-wing unmanned aerial vehicle platform disclosed by the present invention, the technical solution of the present invention will be clearly and completely described in the following cases, and the data processing flow chart Such as Figure 5 shown.

[0090] This example discloses a track generation method for reducing magnetic interference of a fixed-wing unmanned aerial vehicle platform, including the following steps:

[0091] Step 1: Coordinate system definition.

[0092]In order to plan the mission track, it is necessary to define the coordinate system. The coordinate system that needs to be defined or selected includes: the "Northeast" navigation coordinate system and the fixed-wing UAV system. In addition, it is necessary to query the geomagnetic field of the mission area. Vector information. The coordinate system is defined as ...
