Associated with each instrument is a means (3) for commanding motion in that instrument and a pointing control system (5) for imparting motion in that instrument in response to a command (4) from the commanding means (3). Spacecraft motion compensation logic (25) compensates for instrument pointing errors caused by instrument-motioninduced spacecraft motion.
