520 |a"The implementation of attitude control system control functions is usually made by special electronics design comprising discrete electronics in which each individual function is performed by a distinct part of the electronics. Such systems are usually inflexible in design and difficult to implement when sophisticated control schemes are required. Digital control systems permit precise control function generation (elimination of drift and noise), implementation of complex control algorithms and high reliability. Digital control systems are best implemented by a programmable control system processor. This report, prepared under contract for the Department of Communications, presents the results of a study to determine the state-of-the-art of spaceworthy computer hardware and to make recommendations for an on-board computer for the multi-purpose bus satellite Attitude Control System"--Summary.
