LAPAN-A3/IPB multispectral images have been systematically corrected for both geometric and radiometric distortions by using pre-flight imager calibration data as well as in-orbit satellite metadata such as satellite position and attitude. However in several cases, star tracker sensor as the main attitude sensor, could not provide satellite attitude data as needed, which causes some significant performance degradation of the resulting image correction. This research aims to provide satellite attitude data needed for image correction based on multispectral image captured. The research characterizes the relationship between band coregistration distortion occurs on the image to satellite attitude while imaging. Measurements and data fitting which have been conducted show that satellite attitude while imaging has strong relationship to band coregistration distortion caused. However, the accuracy of satellite attitude calculated from band coregistration distortion has moderate accuracy, for about 3 degree for each satellite axis. Although the accuracy produced can be considered low for other applications, it is good enough to provide attitude data needed for image correction purpose.
