A dual fault tolerant control system for controlling power delivered to an actuator from a power source includes decoders which accept commands representing the length of time power is to be applied to the actuator. Controllers process the command and control power inhibits based upon the length of time indicated by the command for supplying power to the actuator. The dual fault tolerant feature allows reassurance that power is applied to the actuator for the length of time dictated by the command.


[ We claim:] [1.] Apparatus for controlling the firing of engine on a space craft, characterized by:actuator means for activating the engine;first controller means for containing a plurality of stored engine burn times, for receiving a first encoded signal to recall one of said stored engine burn times and for providing a first switch signal with a duration of said one of said stored engine burns times;second controller means for containing said plurality of stored engine burn times, for receiving a second encoded signal to recall said one of said engine...
