Autonomous navigation system for drone and navigation method of autonomous navigation system

Abstract

The invention discloses an autonomous navigation system for a drone and a navigation method of the autonomous navigation system. The system comprises a parameter navigation module, a radar navigation module, a central processing module, an information storage module and a course control module, wherein the parameter navigation module, the radar navigation module and the information storage module outputs information to the central processing module, the information is processed optionally, and the processed information is output to the course control module for navigation. The navigation method includes: when a GPS signal is instable or lost temporally, the parameter navigation module outputs state parameters to the central processing module, and the state parameters are processed to obtain flight parameters; when the GPS signal is lost for a long time and the parameter navigation module fails, the radar navigation module is used to output course information; when the GPS signal is lost for a long time, the parameter navigation module fails and a radar signal cannot be received, the central processing module is used to perform route planning. By the system and the method, accurate navigation can be provided for the drone when the GPS signal is lost.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle autonomous navigation system and a navigation method, in particular to an unmanned aerial vehicle autonomous navigation system that can cope with the situation of no GPS signal. Background technique [0002] UAVs have the advantages of small size and low cost, and with the rapid development of flight control technology, communication technology and electronic technology, the performance of UAVs has been continuously enhanced, and the types of UAVs have continued to increase, making them suitable for military and civilian applications. The demand is increasing and the usage rate is increasing day by day. However, due to the limitations of the UAV platform, it is unable to judge the route and flight path by itself, so there are very few technologies that can truly realize autonomous navigation and flight. [0003] At present, the solution to UAV navigation is GPS navigation, which relies heavily on GPS...

Problems solved by technology

However, due to the limitations of the UAV platform, it is impossible to judge the route and flight path by itself, so there are few technologies that can truly realize autonomous navigation flight

[0003] At present, the solution to drone navigation is GPS navigation, which relies heavily on GPS satellite signals. When the signal is unstable or lost, the drone cannot fly autonomously.
