Abstract: Provided is an apparatus for geometrically correcting an image from a geostationary remote sensing satellite, the apparatus being configured to perform the image navigation and registration on image data from a geostationary remote sensing satellite. The apparatus includes the landmark determination part configured to acquire landmark information associated with a first image and the navigation filter configured to calculate a state vector for correcting at least one of the attitude error, the orbit error, and the payload misalignment error with respect to the first image based on the landmark information.
