Abstract

The invention discloses an unmanned aerial vehicle fixed-point landing guiding method and system and is to provide the unmanned aerial vehicle fixed-point landing guiding method and system, which is high in positioning accuracy. The fixed-point landing guiding method comprises the steps of 1) construction of a guiding system; 2) determination of position of an unmanned aerial vehicle; 3) adjustment of horizontal position of the unmanned aerial vehicle; and 4) unmanned aerial vehicle vertical drop. The system is high in anti-interference capability, low in use cost and easy to maintain.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a fixed-point landing guidance method and system for an unmanned aircraft. Background technique [0002] With the development of my country's flight technology, the application of unmanned aerial vehicles is being promoted and popularized. However, there are still many problems to be solved in order to truly realize the application of unmanned aerial vehicles. Accurate landing is one of the difficulties we are currently facing. [0003] At present, the navigation of drones mainly relies on satellite positioning technology, but the accuracy of satellite navigation and positioning is generally within the range of 5 meters, and it can reach 2.5 meters better. Such accuracy is unacceptable for tasks that need to accurately return to a specific location. [0004] Chinese Invention Patent Publication No. CN204845675U discloses an unmanned sampling aircraft, but does not mention the me...
