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 like 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 fi...

Abstract

The invention relates to a track generation method capable of reducing magnetic interference of a fixed-wing unmanned aerial vehicle platform, is applicable to magnetic interference control on fixed-wing unmanned aerial vehicle avionics devices and belongs to the technical field of magnetic sensing. The method provided by the invention further reduces interference of a fixed-wing unmanned aerial vehicle magnetic field on onboard high-precision equipment by generating specific track points which do not interfere with task execution under the premise that the magnetic interference of the platform can not be completely eliminated after magnetic compensation is performed on a fixed-wing unmanned aerial vehicle in advance; and the method has the advantages of low cost, easy operation, high track point precision and easy realization. Besides, the method provided by the invention can also be operated even under the condition of being lack of a professional knowledge background, so that the method can be widely applied to task path planning in fixed-wing unmanned aerial vehicle engineering application.
