Abstract

The invention discloses a positioning method, a data center, a client terminal and a positioning system, and belongs to the technical field of differential positioning. The technical problem that the cost of an existing data center and the cost of an existing differential positioning system are high is solved. The positioning method includes the steps that a datum station sends the datum station observed quantity to the data center; the data center receives the datum station observed quantity; the data center works out the differential correction according to the datum station observed quantity; the data center sends the differential correction to the client terminal; the client terminal receives the differential correction; the client terminal works out differential positioning results according to the self client terminal observed quantity and the differential correction.

Description

technical field [0001] The invention relates to the technical field of differential positioning, in particular to a positioning method, a data center, a client and a positioning system. Background technique [0002] With the emergence of the Global Navigation Satellite System (GNSS for short), researchers are constantly studying how to improve the application range and positioning accuracy of satellite navigation technology. In recent years, differential positioning technology has developed rapidly due to its unique advantages. Its combination with traditional wireless communication technology and the latest mobile Internet has derived various location service systems based on industry applications and serving the public. [0003] The current differential positioning systems tend to be composed of strong centers and weak terminals. All clients (rovers) transmit their own observations and initial positioning results to the data center through the communication network, and th...
