Navigation corrective control system

Abstract

The invention discloses a navigation corrective control system, belonging to the technical field of automatic navigation control. The navigation corrective control system is characterized by comprising a control module (1), a GPS (global positioning system) receiving module (2), a route planning module (3), a node judgment module (4), a distance judgment module (5), a timing module (6) and a control module (7). Compared with the prior art, the navigation corrective control system has the advantages of simple structure, convenience in control, high reliability, convenience in maintenance, and the like.

Description

technical field [0001] The invention belongs to the technical field of navigation automatic control, and more specifically, belongs to a navigation correction control system. Background technique [0002] With the popularization of automobiles and the construction of roads, inter-city economic exchanges have become more frequent, and the area of ​​activities has become larger; in order to improve the quality of life, a large number of leisure activities and adventure activities have been held so that we are not limited to what we know In a small area of ​​, it often happens that you don't know the way or can't find your destination. The space part of GPS is composed of 21 working satellites, which are located in the sky above 20200km from the earth's surface, evenly distributed on 6 orbital planes (4 on each orbital plane), and the orbital inclination is 55°. In addition, there are 3 active satellites Backup satellites are in orbit. The distribution of satellites makes it ...
