Abstract

The invention discloses a distributed Cloud RTK location method. The method comprises: selecting a settled reference station; setting a standard coordinate position and sending it to a centralized control center; distributing a cloud location resolving center that belongs to the settled reference station by the centralized control center; sending the observation data and the standard coordinate position to the cloud location resolving center by settled reference station; coarsely positioning and sending coarse positioning to centralized control center by a moving station; distributing a cloud location resolving center that belongs to the moving station by the centralized control center; obtaining the observation data and sending it to the cloud location resolving center by the moving station; coarsely positioning the moving station by the cloud location resolving center; selecting a datum reference station matched with the moving station; and precisely positioning to the moving station and sending precise positioning to the moving station by the cloud location resolving center. The invention also discloses the positioning system of the location method. The method and system have a high positioning accuracy, and realizes the large-scale localization solution from point to area. The data-processing pressure is low in large-scale applications.

Description

technical field [0001] The invention specifically relates to a distributed cloud RTK positioning method and system. Background technique [0002] 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 coordinate system. The real-time positioning accuracy can reach the centimeter level, and has the advantages of good real-time performance and fast speed. The basic principle of RTK is that the reference station and the rover receive satellite signals at the same time, and the reference station transmits the observation data (mainly carrier phase, pseudo-range) and the standard coordinate position of the reference station to the rover through a data link (modem, radio or communication network). Station, the mobile station uses software to reduce the observation error of the mobile ...
