Abstract

The invention relates to navigation system in area which includes: several pilotage indicating devices set in definite position of area; navigation device which can generate navigation information based on data packages sent by the pilotage indicating device, electronic map and destination information, thereinto, the navigation device receives operation command input by user and indicates destination and receives property information sent by pilotage indicating device nearest to the navigation device, the process module of the navigation device obtains the navigation path based on property information, destination and electronic map, and the navigation path is as navigation information to output to the navigation information output part. The navigation system can generate navigation path and indicate navigation information of user, so effect of navigation in area can be realized.

Description

【Technical field】 [0001] The present invention relates to a navigation system used for navigation in a small area, in particular to a navigation device that utilizes the signal transmission of a navigation device carried by the user and a landmark indicating device set at a fixed position to locate the user's location, and the navigation device uses the user's location, electronic The map and the destination generate and output the navigation path, so as to realize the navigation system for navigating in the area. 【Background technique】 [0002] The current positioning and navigation technology generally adopts the Global Positioning System (GPS, Global Positioning System), which is a global positioning, navigation and timing system composed of 24 satellites launched by the US Department of Defense. Fly around the Earth in six orbits of 20,000 kilometers. There are four satellites in each orbit, and the signals from the four satellites can be received at any point on the ea...
