A positioning system and method for a maglev train, the positioning system comprising an onboard magnet mounted at the bottom of a train, two grating arrays laid on train tracks side by side in the traveling direction of the train, an optical pulse generation module and a data processing module. The data processing module performs first-stage train positioning according to drift conditions of the center wavelengths of the marking gratings, performs second-stage train positioning according to drift conditions of the center wavelengths of the first grating array, and performs third-stage train positioning according to drift conditions of the central wavelengths of the second grating array, so as to determine the track positions where the train arrives step by step.
