Abstract

The invention provides a global navigation positioning system information processing method and device, a central station and a system, and the method comprises the steps that a front-end module receives request information sent by a mobile station, and the request information comprises approximate position information of the mobile station; the front-end module determines an identifier of a virtual reference station to be created according to the approximate position information of the mobile station, and sends the identifier of the virtual reference station to a plurality of service engines which are backups for each other; and each service engine creates a virtual reference station according to the identifier of the virtual reference station, calculates differential correction data corresponding to the virtual reference station, and sends the differential correction data corresponding to the virtual reference station to the front-end module. The method can ensure that the center can provide services continuously, and the center station can provide accurate services continuously when a plurality of service engines are deployed.

Description

technical field [0001] The present application relates to the field of positioning technology, in particular, to a method, device, central station and system for processing information of a global navigation and positioning system. Background technique [0002] Global Navigation Satellite System (GNSS for short) GNSS is a navigation and positioning system that can provide users with all-weather three-dimensional coordinates, speed and time information anywhere on the earth's surface or in near-earth space. Among them, the differential positioning technology is an important technology involved in the GNSS system. It refers to receiving satellite signals synchronously with the mobile station through the continuously operating reference stations (Continuously Operating Reference Stations, CORS for short) whose coordinates are known accurately, and considers that the mobile station and its nearby CORS There is the same error, and the error elimination and positioning are realize...
