Sperry NAVDAC Computer:
| NAVDAC was an acronym for Navigation Data Assimilation
Computer, which describes concisely what the equipment was, and what it did.
It's unusual for an acronym to end up being so precisely correct! It
was a computer, a general purpose computer to be more precise, which ran a
program that assimilated navigation data.
The original NAVDAC on the T-AGS was a Sperry computer built to a UNIVAC design. See the excellent commentaries by John Prough and Jack Keenan. Photos of the computer, which unfortunately do not show the face of the control console, are here and here. The computer consist of both the three cabinet stacks seen in the photo, one behind the civilian tech rep on the left, and one behind LCDR Hammer on the right. By ca. 1969-1970 the Sperry NAVDAC had been replaced on the T-AGS by the Bunker Ramo CP677, the civilian version of the Navy AN/UYK-1, the Navy's first general purpose digital computer (at least to my knowledge). |

(I remember this as "Ships Array Sonar System". Chet Headley, who worked for
General Instruments, the manufacturer, recalls it to mean "Sonar Array Survey
System". The NOAA reference below says "Sonar Array Sounding System". Any
other translations out there?)

Chet Headley notes that these units started out as electric typewriters from
IBM. The I/O portion was originally designed and built by NASL/NSSNF (or
whatever their name was at the end).
