| Research Abstract |
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.
