Cellular network RTK positioning charging method and system

Abstract

The invention discloses a cellular network RTK positioning charging method. The method comprises selecting a fixed reference station, setting a standard coordinate, acquiring observation data and sending to a concentrated control center, wherein the concentrated control center distributes a reference station scheduling center; the fixed reference station computes positioning data and sends the positioning data to the reference station scheduling center; a moving station coarsely positions and sends the coarse positioning data to the concentrated control center; the concentrated control center distributes the reference station scheduling center; the reference station scheduling center matches a reference station; the moving station performs the positioning; the concentrated control center updates pairing information; the moving station and an instant reference station are mutually converted; the reference station scheduling center authenticates the reference station, computes the income and the expenditure of the reference station and reports the income and the expenditure to the concentrated control center; the concentrated control center comprehensively manages the data. The invention further discloses a system for positioning and charging by use of the positioning method. The system disclosed by the invention is fast in positioning speed, high in precision, and low in cost, and is small in data processing pressure when being applied in large scale; and the positioning terminal can acquire a certain economic benefit.

Description

technical field

[0001] The invention specifically relates to a cellular network RTK positioning and charging method and system. Background technique

[0002] In recent years, the application of high-precision satellite positioning and navigation systems has extended from the traditional surveying and mapping field to driving test, intelligent control, unmanned driving, unmanned aerial vehicles, remote sensing and other fields, resulting in the number of high-precision satellite navigation terminals (rovers) is increasing. The increasing number of high-precision satellite positioning and navigation applications and positioning terminals makes the demand for high-precision network RTK technology more and more obvious.

[0003] RTK (Real Time Kinematic) technology is a real-time dynamic positioning technology based on carrier phase difference. It is based on real-time processing of carrier phase observations of two stations, and provides 3D positioning results in the specified...
