Accurate attitude estimation of spacecrafts is the main requirement to provide good geometric performance of remote sensing imagery The ASTER/SWIR subsystem has six linear-array sensors arranged in parallel and each line scans the same ground target with a time interval of 356.238 ms between the neighboring bands. The registration performance between bands becomes worse when attitude fluctuation occurs during a time lag between the observations. Since the time resolution of line scan is higher than that of the attitude information provided from the satellite, attitude data are estimated with high frequency. We succeeded in correcting the image registration error using the revised attitude information As a result, the image distortion of 02 pixels caused by spacecraft attitude jitter is reduced to less than 0.08 pixels, showing that band-toband registration errors of a sensor with parallax observation are available to improve the image distortion caused by attitude fluctuation This technique is applicable to an observation sensor with the same parallel configuration on the focal plane, such as EO-1/ALI, FORMOSAT-2 and SELENE/LISM.

ASTER/SWIR子系统由6个平行排列的线阵传感器组成，每条线阵对同一地面目标进行扫描，相邻波段之间的时间间隔为356.238 ms。当观测间隔时间出现姿态波动时，波段间配准性能变差。由于线扫描的时间分辨率高于卫星提供的姿态信息，因此姿态数据的估计频率较高。利用修正后的姿态信息成功地校正了图像配准误差，将航天器姿态抖动引起的图像畸变从02个像素降至0.08个像素以下，表明视差观测传感器的带间配准误差可以改善姿态波动引起的图像畸变，该技术适用于焦平面上具有相同平行配置的观测传感器。例如EO-1/ALI， FORMOSAT-2和SELENE/LISM。
