一种无人机自主导航系统及其导航方法
摘要：
本发明公开了一种无人机自主导航系统及其导航方法，所述系统包括参数导航模块、雷达导航模块、中央处理模块、信息储存模块和航向控制模块，其中，参数导航模块、雷达导航模块和信息储存模块输出信息到中央处理模块，然后任选地进行处理，然后输出给航向控制模块，进行导航；所述导航方法如下进行：当GPS信号不稳定或短暂丢失时，参数导航模块输出状态参数到中央处理模块，进行处理，得到飞行参数；当GPS信号长时间丢失且参数导航模块失效时，利用雷达导航模块输出航向信息；当GPS信号长时间丢失、参数导航模块失效且无法接收到雷达信号时，利用中央处理模块进行路径规划；本发明所提供的系统和方法能够在无GPS信号下为无人机提供准确导航。
摘要（英）：

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.
