The invention discloses a CORS network resolving method and system considering coordinate change of a reference station and a medium, and the method comprises the steps: constructing a baseline resolving double-difference observation value model which comprises a double-difference pseudo-range observation equation and a phase carrier observation equation of an ionosphere-free combination; constructing a single epoch error equation, and resolving to obtain real-time estimation coordinates of each reference station; calculating a single station coordinate of each reference station through PPP precision point positioning, comparing the single station coordinate with a real-time estimation coordinate of the reference station, and determining the reference station which does not move; and taking the reference station which does not move as a main reference station, and carrying out positioning calculation on the moving station according to the position information uploaded by the moving station in real time.
