English: First Stage Avionics Module (FSAM): The Ares I-X avionics systems include components from the Atlas V Evolved Expendable Launch Vehicle, the Space Shuttle Program, and off-the-shelf developmental flight instrumentation (DFI), as well as a new component that will translate commands between the Atlas and Shuttle hardware. DFI hardware was installed throughout fabrication to reduce the amount of work performed at KSC. The hardware work is being managed by MSFC under contract to Jacobs Engineering in Tullahoma, Alabama and developed by Lockheed Martin in Denver, Colorado. Lockheed, which developed the Atlas avionics, also developed a systems integration laboratory (SIL) to simulate the flight configurations of the avionics and test the various systems’ ability to work together.
