Problems solved by technology

In the indoor environment, the GPS system cannot complete the positioning due to the blocking of satellite signals.
In the case of mobile phone base station positioning technology without GPS assistance, the accuracy depends on the distribution of base stations and the size of the coverage area. However, the positioning speed of this method is slow and the error is relatively large

Abstract

The invention discloses a navigation system based on location based services and a navigation display method thereof. The navigation system comprises a storage module, a processing module, and a display module, wherein the storage module stores regional information and an regional feature point in a command character string, the processing module analyzes the command character string containing the regional information, orderly draws an indoor map, and compares the regional feature point and the regional information so as to analyze a current position; the display module displays the regional information, the current position and the indoor map.

Description

【Technical field】 [0001] The present invention relates to a navigation system, in particular to a location based service (Location Based Service, LBS) navigation system and a navigation display method thereof. 【Background technique】 [0002] Generally, it is difficult for strangers to find the place they want to go to when they first come to a more complicated room (such as a shopping mall or an airport) or in a small area (such as a community or theme park), and they cannot quickly get what they want. Information. [0003] The existing method is to provide regional map information, but you need to arrive at the scene to observe. At the same time, in order to provide eye-catching information, because the amount of information it carries is extremely scarce, if you want to view detailed information, you often need to check the map in advance on the Internet, or ask passers-by or stores. However, this method is difficult to achieve in a complex indoor environment, and users ...
