Abstract

The invention discloses a method for determining the course of an unmanned aerial vehicle and an unmanned aerial vehicle. The method includes: obtaining the current first heading angle of the UAV through the first sensing system, and obtaining the current second heading angle of the UAV through the second sensing system; judging whether the second heading angle is based on the first heading angle Valid; if the second heading angle is invalid, determine the first heading angle as the current heading angle of the drone. The invention solves the technical problem in the prior art that, due to the influence of interference and other factors, when the electronic compass or the real-time dynamic difference method measures the heading angle, the measured heading of the UAV is wrong.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a method for determining the course of an unmanned aerial vehicle and an unmanned aerial vehicle. Background technique [0002] To achieve autonomous navigation, the drone must be able to obtain the position and heading of the drone. The position of the drone is generally obtained by GPS (Global Positioning System, the abbreviation of Global Positioning System), and the heading of the drone is generally obtained by the electronic compass. It is fused with IMU (Inertial measurement unit, inertial measurement unit), or the heading data is measured based on the dual-antenna RTK (real-time dynamic difference method, the abbreviation of Real-time kinematic) system. [0003] The electronic compass itself is susceptible to interference and cause heading errors. Among them, electronic compass interference is divided into two types: one is when the UAV suddenly enters a strong magn...
