Imaging system
OPTSAT-3000 has a high-resolution optical imaging system known as Jupiter, which is able to deliver panchromatic images with a resolution of while operating the multispectral channel at the same time. These imaging detectors, combined with a telescope from an altitude of almost , allows OPTSAT-3000 to cover a ground track wide.[
