Embodiment Construction

[0039] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0040]In the present invention, when the mobile station needs high-precision positioning, it uses the wireless communication network to send the differential correction data request and the GPS positioning data it currently receives to the data processing and control center in real time, and the data processing and control center according to the mobile station The position of the station constructs a virtual reference station, and uses the data processing and control center to calculate the differential correction data, and then uses the mobile communication network to send it to the mobil...

Abstract

This invention provides one method, system and device for mobile station accurate guiding, which comprises the following steps: a, mobile station sends difference data require and its current GPS data through wireless communication net to control center; b, the center forms virtual reference station according to mobile station and using data process center for correction data through wireless communication new to feed back data to mobile station; c, the said mobile station computes accurate GPS position data for guiding according to the correction data and its GPS position data.

Description

technical field [0001] The present invention relates to the field of communications, and more particularly, to a method, system and device for precise navigation of a mobile station. Background technique [0002] At present, the Global Positioning System (GPS) technology is widely used in agriculture, forestry, water conservancy, transportation, aviation, surveying and mapping, security, military, electric power, communication, urban management and other fields. Autonomous navigation has also become a new application trend. The specific implementation method is as follows: firstly, input the starting point and ending point on the electronic map to plan an optimal route; then use the navigator installed in the mobile station to receive the GPS positioning information in real time, and prompt the driving route of the vehicle. However, at present, ordinary users can only receive GPS signals with standard accuracy for free, and the accuracy is only 20-30 meters. Even after vari...
