Satellite control data in the form of state vectors and state vector products are generated representing the position and geometric relationships of the space craft to the Earth, sun, moon, and specific locations on the Earth. These data is used to control attitude, SADA steering, antenna pointing, momentum upload, and Earth sensor intrusion. An onboard orbit propagator predicts the data and integrates the data into the various control systems for the respective function.
