Abstract: Provided is an apparatus for controlling a driving speed of an antenna of a mobile satellite travelling in an orbit. The apparatus may include a calculator configured to calculate an azimuth position range and an elevation position range for an effective beam width of the antenna based on an antenna orientation at which the antenna of the mobile satellite is oriented correctly to a ground station from a point in the orbit, and a controller configured to control a speed of the antenna based on a first azimuth in the azimuth position range and a first elevation in the elevation position range.

Abstract: Provided is an apparatus for controlling an orbiting satellite by sensing a change in a yaw angle of the orbiting satellite and calculating a ground sample distance (GSD) based on the yaw angle. The apparatus may include a sensor configured to sense a yaw angle corresponding to yaw steering of the orbiting satellite, and a processor configured to calculate, based on the yaw angle, a GSD corresponding to a length of a pixel projected onto a planetary surface scanned by the orbiting satellite.
