Embodiment Construction

[0022] Such as figure 1 As shown, an anti-jamming cluster UAV system includes a beacon UAV and a task UAV; when the task starts, the beacon UAV obtains precise position information through satellite positioning or differential positioning, and passes It is transported or autonomously flies to a position outside the pre-set coordinates of the disturbed area; the beacon UAV measures its own absolute coordinates, and calculates a positioning result based on the absolute coordinates of the beacon UAV. The relative coordinate system of the task UAV described above; the beacon UAV continuously and in real time broadcasts non-radio signals to the mission UAV, and the beacon UAV acts as a low-altitude communication and positioning relay platform Provide near-air positioning and command functions for the mission UAV; the mission UAV receives the non-radio signal of the beacon UAV, calculates its own coordinate position, performs its own positioning and receives mission information ; T...

Abstract

The invention discloses an anti-interference cluster unmanned aerial vehicle system and a communication and positioning method thereof. The system comprises beacon unmanned aerial vehicles and task unmanned aerial vehicles. The main technology between the cluster unmanned aerial vehicles is wireless ultraviolet light communication, and the ultraviolet light communication has the advantages of interference resistance, all-weather work, high confidentiality, non-line-of-sight communication and the like; according to the scheme, the beacon unmanned aerial vehicle can reconstruct coordinates, accurate positioning, task execution, task evaluation and the like of the task unmanned aerial vehicle in an electromagnetic interference environment near the ground are achieved, the unmanned aerial vehicle system is not affected by any form of electromagnetic interference, and the characteristics and advantages of a cluster unmanned aerial vehicle system can be fully played.

Description

technical field [0001] The invention relates to the field of aviation technology, in particular to an anti-interference cluster unmanned aerial vehicle system and its communication and positioning method. Background technique [0002] Swarm drones are an important direction for the development of drones in the future. With the advent of intelligence in the world, intelligent equipment robots also appear in large numbers in society, and cluster drone tasks, as an important form of intelligence, are being up-and-coming. In the future world, in the case of increasingly complex communication and intelligence, our environment will be full of various radios, which is extremely unfavorable for the communication of swarm drones. [0003] But no matter how the UAV swarm develops, it cannot do without communication technology. In a complex electromagnetic environment, how to ensure UAV communication and precise positioning has become a top priority. Contents of the invention [0...
