Abstract. For the on-orbit high resolution satellites, attitude jitter is a common and complex phenomenon which may deteriorate the image quality and mapping accuracy. In this paper, an image-based jitter inversion and estimation model is derived considering time delay integration (TDI) effect, and the attitude is then updated by taking into account the estimated jitter information. The imagery is finally resampled through virtual re-imaging using the updated accurate attitude to improve the image geometric quality. The proposed method is validated by experiments using the Chinese Ziyuan-3 (ZY-3) satellite imagery.
