AN/GSS-1
The AN/GSS-1 Electronic Search Central was a United States radar/communication system 1st fielded in the mid-1950s for Project Nike with a "medium-range, transportable radar set [used] as a search radar". The Cold War central included a Western Electric "AN/TPS-1D radar and AN/TPX-19 interrogator system…in a fully enclosed shelter [with communications] provided by radio receiving set AN/GRR-5, radio set AN/GRC-9 and by three telephone lines". An intercom system for the "four-man team" was within the shelter of "about 6 feet high, 6 feet wide and 12 feet long" with a  personnel area [and] equipment compartment. As part of the Hughes AN/MSG-4 Antiaircraft Defense System, the team in the radar section of a battalion would use the AN/GSS-1 to provide radar tracks to the battalion operations center, e.g., the Raytheon AN/MSQ-18 Battalion Missile Operations System for command and control of (fire distribution to) up to 4 Nike fire control/launch sites. An AN/GSS-1 was used in Germany as late as 1978 after being fielded as part of the AN/TSQ-73 Guided Missile Air Defense System.
