Abstract

The invention provides a positioning system, a terminal, and a positioning method. The positioning system comprises a reference station, a cloud server and a positioning terminal. The cloud server includes: an acquisition module, which is used for collecting differential data of the reference station in real time; a storage module, which is used for storing the differential data that are collected in real time and information of reference station corresponding to the differential data as well as a corresponding relation between the differential data and the reference station; a determination module, which is used for determining a reference station requested by a differential data request according to the differential data request sent by the positioning terminal; and a sending module, which is used for sending the differential data corresponding to the determined reference station according to the corresponding relation between the differential data and the reference station. According to the invention, the positioning efficiency is improved and the number of equipment used for differential positioning is reduced.

Description

Technical field [0001] The invention relates to the technical field of terminal positioning, in particular to a positioning system, a terminal and a positioning method. Background technique [0002] Differential positioning (Differential positioning) is also called relative positioning, which is widely used in a variety of positioning occasions, such as geodetic positioning or engineering measurement positioning where positioning is required. When implementing differential positioning, you can simply place a GPS (Global Positioning System, Global Positioning System) receiver (called a reference station) on a point with known coordinates, and use the known GPS coordinates and satellite ephemeris to calculate the observation value. The correction value (also called differential data, error correction data), and the correction value is sent to the GPS receiver in motion (called the mobile station) through the radio device (called the data link), and the mobile station applies the re...
