  "Flight Control Computer for Saturn Space Vehicles."

  The flight control computer for Saturn receives attitude signals from the stable platform, rate signals from rate gyros or lead networks, and angle-of-attack information from body-fixed accelerometers or other sensors.

  "Flight Evaluation of the Command and Communication System Aboard AS-501."

  The first test of the command and communications system, a unified frequency S-band system, aboard AS-501 was successful. Compatibility of this system with the MSFN/USB sites was established. The onboard transponder and antenna system including antenna switching performed as predicted. The command performance was excellent with 5747 valid commands received onboard out of 5748 commands transmitted. Data reduction problems prevented a complete analysis of the tracking data. Telemetry system performance was satisfactory with a measured bit-error-rate of 4 x10-5 while over the Ascension Island station. This flight provided valuable data which can be used to define vehicle to-ground-station interfaces, to establish attitude constraints during translunar injection, and to improve operational procedures. One more test as successful as the AS-501 test would qualify the system as operational.; May 3,1968.

  "Flat Cable Engineering Studies for Saturn S-IVB Vehicles."

  This paper describes the engineering approaches, investigations, results and conclusions of two National Aeronautics and Space Administration (NASA) flat-cable contracts from the George C. Marshall Space Flight Center (MSFC) to the Douglas Aircraft Company, Inc., for feasibility studies on the S-IVB stage of the Saturn Vehicle. In addition, the objectives and approaches for a third contract., "Flat-Cable Engineering Study", are discussed. A sister Douglas Paper No. 4186, to be presented by Dr. P. L. Hill, covers in detail the manufacturing aspects of the Flat-Cable Development Program.; Prepared by R.A. Klotz, Advance applications, Saturn Electronics, Missile and Space Systems Group, McDonnell Douglas Corporation for presentation at: IPC/EDN Flat-Cable Seminar, University of Southern California, Los Angeles, California, 20 June 1967.

  "An Iterative Guidance Scheme and Its Application to Lunar Landing."

  A guidance scheme for vehicle flight from lunar orbit to a prescribed point on a spherical, non-rotating moon is presented. The equations of motion have been simplified only to perm it a closed solution for the thrust magnitude and thrust direction. The trajectory computations them selves are made under more realistic and accurate assumptions and are not included.

  "The Iterative Guidance Law for Saturn."

  Summary: "Based on Lawden's equation, semi-explicit,'iterative' Saturn guidance equations are derived, many were successfully flight tested on Saturn I and analyzed for the main Apollo mission and other applications applications."

  "Interface Control Document Definition of Saturn SA-507 Flight Sequence Program."

  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).

  "Interface Problems in Space Experimentation."

  Space experimentation is expanding rapidly. Unmanned satellites are being equipped with precision instruments of greater power, and manned space stations accommodating large crews are in the drawing-board stage. The interface problems between these sophisticated instruments and between man, the spacecraft, and the supporting groundstations are multidimensional. This paper analyzes the scientific/technical areas of space experimentation, and continues with a review of the subsystems and support systems required to supply and operate the large variety of instruments. Areas of major integration efforts are singled out and the requirements for further developments and improvements are listed. A bibliography of 95 references is enclosed to assist in the identification of more detailed reports on all vital aspects of space experimentation.; Archive copy is a photocopy.; Supplement to IEEE Transactions on Aerospace and Electronic Systems, Vol. AES-2, No. 4, July, 1966. Pages 237 to 255.
