Spacecraft device initiation system

A networked initiation system, comprising:

• a control unit;
• at least one non-energetic hold-down and release mechanism (“HDRM”) configured to hold in place one of number of elements and to release the held element upon receipt of an activate command from the control unit;
• a first circuitry associated with the at least one non-energetic HDRM, the first circuitry arranged for arming and firing the at least one non-energetic HDRM associated with the first circuitry, the first circuitry addressable by the control unit;
• at least one energetic device configured to hold in place another one of the number of elements and to release the held element upon receipt of an activate command from the control unit;
• a second circuitry associated with the at least one energetic device, the second circuitry arranged for arming and firing the at least one energetic device associated with the second circuitry, the second circuitry addressable by the control unit;
• and
• an interface bus configured to connect together the control unit, the first circuitry, and the second circuitry, to provide power from the control unit to the at least one non-energetic HDRM, the at least one energetic device, and each circuitry, and to communicate between the control unit and the at least one non-energetic HDRM, the at least one energetic device, and each circuitry,
• wherein an energetic HDRM is at least one of explosive and pyrotechnic, and a non-energetic HDRM is neither explosive nor pyrotechnic,
• wherein the first circuitry and the second circuitry are each uniquely identifiable for communication with the control unit.
