Draft of "Concepts of the Iterative Guidance Law for Saturn Launch Vehicles."
The summary notes, "In 1960, research work was begun to develop new guidance concepts for the Saturn space vehicles. [...] This paper presents the basics of the Iterative Guidance Law developed for Saturn launch vehicles to meet these new requirements of space age guidance. The development of the Iterative Guidance Law and the results and ideas presented in this paper are due primarily to Mr. Helmut J. Horn and his associates in the Dynamics Analysis and Flight Mechanics Division of the Aero-Astrodynamics Laboratory." Marked "Research Review, OK" in the upper right corner of the first page. The document includes corrections and additions to the text in red pencil. -

"General Formulation of the Iterative Guidance Mode."
From the abstract: "This report discusses the iterative guidance mode and its application to three-dimensional upper stage vacuum flight. It is an inertial or closed system mode in that the only inputs required after liftoff are available from the onboard navigation system. That is, the iterative scheme computes steering commands as a function of the state and of the vehicle - velocity, position, longitudinal acceleration, and gravitational acceleration - and the desired cutoff conditions. The guidance commands are updated each guidance cycle, using the updated state of the vehicle. The iterative guidance scheme is a path adaptive guidance scheme in that it will retain its optimization properties under all expected types and magnitudes of vehicle perturbations without any loss in accuracy at liftoff." -

Oral History Interview With Robert McBrayer
After Robert McBrayer graduated college, he reported to the Johnson Space Center in March of 1963. He was there assigned to a section called "Biodynamics" and in that section, they worked on Human tolerances to impact sustaining acceleration and acoustics. Robert was assigned to the acoustics group, and his first job was to design and develop a machine to produce low-frequency pure tones to test humans. He also designed and developed a test chamber for testing humans, and he participated in doing the actual human test with the machines that he helped build. He helped document the results as well. After his venture in doing basic research, he went into an area called "crew's survival equipment design and development," and he was assigned pieces of equipment that were his to design, update, and help build. In 1966, Robert asked to be transferred from the Johnson Space Center to the Marshall Space Flight Center, and he then moved to Huntsville, AL. Robert was immediately put on the Orbital Workshop where they were writing task analysis, and procedures for crew station reviews. They did two of those, on in 1967 and the other in 1968. From the Orbital Workshop, he was responsible for all the crew interfaces on adapter, etc.Tags Oral History -
"Space flight : first draft."
Appears to be a rough dfraft with editorial comments and revision notes. Includes references to figures and tables.; Page 31 is missing. Pages 37 through 44 do not exist; there is a note about this on page 36. Page 67 also does not exist. -
"A Comparison of an MIT Explicit Guidance Principle with MSFC Iterative Guidance."
From the summary: "Both [guidance] schemes steer toward a specified end point. The MIT scheme uses thrust to cancel out the effective gravity, a nonlinear term, which may be inefficient in certain cases. The MSFC scheme is more closely connected with calculus of variations and optimization theory in a reasonable degree of approximation."
