An evaluation of mission requirements for postulated earth observation orbital payload experiments has indicated that high accuracy pointing and stabilization must be provided for adequate performance. A computer simulation has been conducted to determine the capabilities of an auxiliary pointing system which employs a combination of conventional gimbals and magnetic bearing actuators. This Annular Suspension and Pointing System (ASPS) is found to be a viable means of providing the high slew rates associated with landmark tracking from low orbit, while simultaneously achieving the high degree pointing and stabilization dictated by science payload requirements.
