OPERATION GREENHOUSE. Scientific Director's Report of Atomic Weapon Tests at Eniwetok, 1951. Annex 1.11. Timing and Firing and Fiducial Markers,

Abstract

An automatic remote-control system armed and fired the bomb and sent out a sequence of time signals to experimental equipment on the atoll. A central station at Parry Island sent signals via submarine cables to a timer station on a shot island. The timer station controlled signals to the zero station and to experiments on the island, and through auxiliary stations, it also controlled signal distribution on adjacent islands. Light-sensitive triggering units for apparatus and for accurate standard zero-time reference were provided in the form of Blue Boxes, or fiducial markers.
