Problems solved by technology
During the flight, judge whether the trajectory of the nose direction of the aircraft determined by the two RTK antennas is consistent with the actual flight direction. Stop and make a forced landing, and then switch the connection between the two RTK antennas and the dual female ports of the aircraft, but this method not only consumes time and power, but also causes the aircraft to lose control when the aircraft cannot hover in an emergency

Embodiment Construction
[0098] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0099] At present, the first RTK antenna should be connected to the first female port of the aircraft, and the second RTK antenna should be connected to the second female port of the aircraft. However, since the first RTK antenna and the second RTK antenna have the same appearance and structure, the When the first RTK antenna and the second RTK antenna are installed on the aircraft, the first RTK antenna is connected to the second female port of the aircraft, and th...

The invention, which relates to the technical field of unmanned aerial vehicle control, discloses a nose direction correction method and device and a flight controller, thereby simplifying the antennainstallation self-checking process on the premise of ensuring safe flight of the aircraft. The correction method comprises the following steps: acquiring attitude information of an aircraft and navigation information of the aircraft, and acquiring a nose measurement direction according to the attitude information of the aircraft and the navigation information of the aircraft; determining that thenose measurement direction is the nose correction direction under the condition that the nose measurement direction is the same as the nose reference direction; and otherwise, reversing the nose measurement direction to obtain the nose correction direction for navigating the aircraft. Besides, the nose direction correction device is used for realizing the method. The nose direction correction method and device and the flight controller can be applied to unmanned aerial vehicle control.
Description
technical field [0001] The invention relates to the technical field of unmanned aerial vehicle control, in particular to a method and device for correcting the direction of a nose, and a flight controller. Background technique [0002] Carrier phase difference technology (Real-time kinematic, abbreviated as RTK) is a real-time dynamic measurement technology, which can perform centimeter-level precise positioning of a positioning object, and is often used in aircraft navigation. [0003] At present, the aircraft uses two RTK antennas to accurately position the aircraft at the centimeter level to determine the direction of the aircraft's nose, so as to achieve the purpose of navigating the aircraft. Connected to the dual-female interface of the aircraft, so that the direction of the aircraft's nose determined by the two RTK antennas is opposite to the actual aircraft's nose direction, causing the aircraft to lose control and even crash. [0004] In order to solve the above pr...
