The invention provides a system and a method for real-time differential positioning. The method comprises the following steps: a user terminal sending a login request to a central differential processor; the central differential processor using a reactor to implement the distribution of the login information after receiving the login request, and calling an identity verification module to completethe user login verification; sending the GNSS raw observation data to the central differential processor in real time after the user login verification succeeds; and the central differential processor also receiving the GNSS raw observation data of the user and the base station through the reactor, and then performing decoding, and performing terminal positioning and data service through the decoded data. The system and the method for real-time differential positioning method improve the single differential calculation efficiency, reduce the consumption of computing resources, further providevarious types of special customized services, serve the business users, facilitate the high-precision positioning technology to permeate in the civil field, and expand the user groups.
