ABSTRACT:
Apparatus for use in determining the orientation of a spinning spacecraft d for controlling the attitude motion thereof. In response to commands from an external processor, the apparatus enables a selected thruster at a commanded time delay after a solar-or earth-sensor reference pulse and fires the thruster a commanded number of times. The time difference between various sensor inputs is measured to determine spin rate and other data which is used by the external processor in calculating the firing sequence of the thrusters.
