IBM and UNIVAC in the Apollo Program

IBM and UNIVAC in the Apollo Program

Summary: IBM and UNIVAC were the key system integrators for the Apollo program. IBM provided broad computer support on a number of fronts including guidance systems on the Saturn V vehicle itself, whereas UNIVAC's computers were critical to the Deep Space Tracking Network (DSTN) required for upstream and downstream telemetry to and from the spacecraft.Read more about IBM and UNIVAC in the Apollo program in Tech Broiler.

  • Several large Deep Space Tracking Network stations with huge radio antennae were required in order to receive and send telemetry and control signals back and forth to the Apollo spacecraft. This particular antenna is 85 feet wide. (NASA)

  • The 210 foot antenna at the Perth station was the subject of the 2000 film "The Dish" starring Sam Neill and Patrick Warburton. It is a largely fictional account which downplays the significance of all of the stations in the DSTN network. During the course of the Apollo 11 mission, several stations were required in order to receive telemetry and television signal from the spacecraft and the moon.

  • The heart of the DSTN telemetry decoding were several dozen UNIVAC 1230 systems deployed on site at the DSTN tracking stations around the world. Originally designed for use on naval vessels, The modified 1230s, known as 642B military computers, used ferrite core memory and were military hardened to handle 140 degree temperatures as well as salt spray.

    ... is at Parkes not Perth

  • RE: DSTN Station at Perth, Australia (IBM and UNIVAC in the Apollo Program)

    Perth (West Coast) has a dish that was very important to the mission, but it was definitely the Parkes dish(East Coast)that was the subject of the movie "The Dish".

  • Univac 1230 at Goddard

    I worked at Goddard as an employee of CSC from 1974 to 1978, and worked on the telemetry systems for the shuttle Approach and Landing Test and Orbital Flight Test projects (as a computer programmer). The telemetry systems ran on the Univac 1230 computer. Several years later, a friend and co-worker from that time gave me a circuit board from a decommissioned 1230. I can't remember if he said it was a flip-flop circuit or a one-shot. Can anyone help me identify it? The following is printed on the connector: A-2333-6 7003700 00. I can provide a photo (I'd post it here if I knew how).

    Thanks!
