    For the purposes of this paper, an onboard checkout system is defined as a system which is built into prime flight equipment, flies with it, and permits a checkout capability to exist during all the major phases of the test and mission life of that prime equipment. Varying degrees of capability may exist in such a system, depending on what is designed into it. This, in turn, is generally dependant on life and mission requirements of the prime equipment, degree of mission checkout required, reliability restrictions,redundancy levels, data management scheme, and equally important, state of the art . Not all checkout can be accomplished with onboard equipment. Mechanical system problems such as leak detection, for example, require techniques that cannot be remotely controlled and evaluated today. On the other hand, such things as in-flight telemetry have been used for quite a long time and will continue to be used for onboard checkout.
  • Spactelegroudata_022508152653.pdf

    A design report which displays and explains how the Spacecraft Television Ground Handling System functions, is designed and what it might be used for in the future.
  • InterControlDocu_051208113245.pdf

    The purpose of this document is to define the flight sequence events, time bases, stage switch selector channel assignments, LVDA Discrete Outputs, Inputs and Interrupts for the Saturn SA-507 & Subs vehicles. Special requirements and restrictions defined in this document will be imposed on the Marshall Space Flight Center and its contractors as applicable, to insure the proper functioning of the equipment in the various stages for required vehicle timing and sequencing to occur as outlined in this Interface Control Document (ICD).
  • Compcontpowe_042908131740.pdf

    This paper describes a real-time digital computer program that controls the application of electrical power to the S-IVB stage of the Saturn vehicle at Cape Kennedy, Florida. Douglas Aircraft Company, the S-IVB stage manufacturer, provided NASA with the program requirements relative to the energizing sequence, voltage and current measurement tolerances, and vehicle system operational tests. International Business Machines Corporation provided NASA with the computer program to satisfy the task requirements. The program conjoined the components of the Electrical Support Equipment (two RCA 110A computers and control and instrumentation devices) into a closed loop system. The supporting operating system program by IBM is described.
