ABSTRACT:
A controller for the attitude stabilization of a satellite. The controller odifies the action of a first control circuit by responding to the signals of attitude .phi. and angular velocity of attitude .phi. developed by the first control circuit. A second control circuit includes a comparator, two Schmitt trigger circuits, two AND elements and two OR elements. Signals from the AND elements and uncorrected thrust nozzle control signals from the first control circuit are supplied to the OR elements. The output of the OR elements control the thrust nozzles of the satellite.
