The intrinsic "anomaly" mechanism of the ground track drift of a satellite in orbit is analyzed and the model of solar radiation pressure accumulation effect in alongtrack direction in zero yaw attitude mode(keeping yaw angle zero in one orbit cycle) is built. Then, the model parameters are estimated using historical observation data through POD. Finally, the accuracy of the new model is verified by using the real ground track of the satellite in 2018. The results show that the accuracy of satellite ground track drift forecast is significantly improved by using the new model. It can provide technical support for developing the control strategy of ground track keeping for this kind of satellite.
