Instrument Unit(IU)

IU is a computer system controls whole of Saturn rocket. This was made by common design through all the series of Saturn I, IB, V.
  • Diameter :260in (6.604m)
  • Height :36in (0.9144m)
  • Weight(Average) :4500lb (2.04ton)
  • Manufacturer:IBM (International Business Machines Federal Systems Div. Huntsville, Ala.)

IU used with Saturn IB is almost the same as the thing developed for Saturn V. Most of the carried instruments and physical size are really the same as the Saturn V's. The main functions of IU are the direction control of the rocket, the ignition control of the engine, the timing control of instruments.

  • The Apollo Guidance Computer: Architecture and Operation

    Praxis July 11, 2010 USD40.46

    The technological marvel that facilitated the Apollo missions to the Moon was the on-board computer. In the 1960s most computers filled an entire room, but the spacecraft’s computer was required to be compact and low power. Although people today find it difficult to accept that it was possible to control a spacecraft using such a ‘primitive’ computer, it nevertheless had capabilities that are advanced even by today’s standards. This is the first book to fully describe the Apollo guidance computer’s architecture, instruction format and programs used by the astronauts. As a comprehensive account, it will span the disciplines of computer science, electrical and aerospace engineering. However, it will also be accessible to the ‘space enthusiast’. In short, the intention is for this to be the definitive account of the Apollo guidance computer.

  • Digital Apollo: Human and Machine in Spaceflight

    The MIT Press September 30, 2011 USD28.21

    As Apollo 11's Lunar Module descended toward the moon under automatic control, a program alarm in the guidance computer's software nearly caused a mission abort. Neil Armstrong responded by switching off the automatic mode and taking direct control. He stopped monitoring the computer and began flying the spacecraft, relying on skill to land it and earning praise for a triumph of human over machine. In Digital Apollo, engineer-historian David Mindell takes this famous moment as a starting point for an exploration of the relationship between humans and computers in the Apollo program. In each of the six Apollo landings, the astronaut in command seized control from the computer and landed with his hand on the stick. Mindell recounts the story of astronauts' desire to control their spacecraft in parallel with the history of the Apollo Guidance Computer.
