An aerial view of Hunter's Point Naval Shipyard, San Francisco, California (USA), with three docked aircraft carriers on 25 August 1971. The carriers are the USS Ranger (CVA-61) (in dry dock), USS Coral Sea (CVA-43), and the USS Hancock (CVA-19) (left).
UNIVAC 490 Real-Time System at NASCOM Network Switching Center, Goddard Space Flight Center, Greenbelt, Maryland, U.S.A. (1965). Designed by Seymour Cray, it consisted of two 30-bit central processor units with 32K core memory each, using 13,819 transistors and 37,543 diodes each, FH880 drums, IIIC Mag tape units and a 1004 card processor and printer. Prior to the advent of NASCOM, the 1957 Minitrack network largely relied on 30 bits/sec teletype lines for tracking the flights of Sputnik, Vanguard, and Explorer. As NASA developed more advanced satellites in the early 1960s, the capability for telecommand grew, and Minitrack was no longer sufficient. Network technologies used in NORAD and SAGE defense systems contributed to the development of NASCOM which formed in 1964 under the administration of the Office of Tracking and Data Acquisition which tied together three tracking and acquisition networks: the Spacecraft Tracking and Data Acquisition Network (STADAN), the Manned Space Flight Network (MSFN), and the Deep Space Network (DSN). Communication links consist of landlines with 60 WPM full-duplex 33 ASR teletype circuits, submarine cable, HF radio and even Continuous Wave (CW). There are three basic Communication Line Terminals: low speed (300BPS), medium speed (1600BPS); and high speed (2000-4800 BPS). Above 4800 BPS, a Communications Control Unit (CCU) is used.
