Abstract: Technique, method and apparatus for obtaining optimized, selfadaptive, attitude control in space vehicles using on-off reaction motor propulsion for torquing the vehicle about its axes of attitude. Formulation to determine a time duration of known thrust to impart a calculated angular acceleration is based on angular velocities and is calculated from maximum permissible angular deviation, an appropriate lesser deviation, initial mass and initial thrust force as parameters and time as a universal variable. Technique provides for operation both in presence of and absence of directional bias forces and includes updating of data representing vehicle parameters. Disclosure includes one apparatus to accomplish the method by application of digital computation.
