The invention discloses a satellite shipborne communication-in-motion satellite-aligning semi-physical simulation method and system, and the method comprises the steps: carrying out the satellite ephemeris calculation and satellite trajectory prediction based on a sath toolbox and customized multivariate two-line report TLE data, and generating a target satellite for a satellite-aligning process of communication-in-motion; carrying out ship jolt simulation based on the sea wave power spectrum empirical function corrected by the sea area features, and adding disturbance to satellites for satellite communication in motion; performing simulation fitting on an actually measured inertial navigation data error model and a drift model based on the Airy variance, and feeding back a three-axis angle of the communication-in-moving antenna system in real time; based on cubic spline interpolation of a sensor error model and a drift model correction interpolation coefficient and multi-sensor synchronization of an extrapolation algorithm, simulation authenticity and data reliability are improved. The communication-in-motion semi-physical simulation platform established by the invention effectively restores the satellite communication process of the communication-in-motion antenna, ensures the stability of communication data input and output, supports introduction of actually measured data for semi-physical simulation, and verifies the accuracy of a satellite algorithm.
