Mobile terminal positioning correction method and system

Abstract

The invention discloses a mobile terminal positioning correction method and system, wherein the method includes: setting a reference point in advance, measuring the standard position data of the reference point; the cloud server obtains the real-time position data of the reference point in real time, and calculates each reference point in real time Corresponding correction coefficient; the mobile terminal sends a correction request including the current positioning data to the cloud server; the cloud server determines the selected reference point among the reference points; generates the current correction coefficient of the mobile terminal according to the correction coefficient of the selected reference point; according to the current correction coefficient Correct the current positioning data. Since the position of the mobile terminal is also consistent with the offset mode of the positioning data of the selected reference point, by selecting the current correction coefficient of the reference point, the current positioning data of the user's mobile terminal can be effectively corrected to obtain a higher accuracy. High positioning results.

Description

technical field [0001] The invention relates to the fields of computer and geographic information science, in particular to a method and system for positioning and correcting a mobile terminal. Background technique [0002] Geographic information system can rely on computer technology to process, store, extract, manage and analyze geographic information. The 3S integrated technology system provides new analysis methods and technical guarantees for solving modern geoscience problems with a wider area and higher complexity; typical applications include, by storing map information in the computer, making electronic Map; then, combined with the global positioning system, people can quickly query the location of the target on the map through the terminal. [0003] As one of the most widely used positioning systems at present, the Global Positioning System (Global Positioning System, GPS) can perform real-time positioning and navigation around the world by using positioning satel...

AI Technical Summary

Problems solved by technology

[0007] In the existing method of position positioning through GPS, the electromagnetic wave signal between the positioning satellite and the receiver will be interfered by the weather environment, such as changes in the ionosphere in the atmosphere, or changes in the earth's magnetic field, etc. Causes the change or offset of the electromagnetic signal delay between the positioning satellite and the receiver. Therefore, when the positioning is performed by the mobile terminal, the positioning data under certain weather conditions will have a large deviation from the actual position.
