Quite a number of things have been going on with regard to AS-206 mission plans, spacecraft configuration, and the LGC computer program development. I would like to take a couple of minutes here to let you know about the latest developments in the latter….
C’ Mission Techniques
Attached are a list of ground rules and working agreements I compiled from my notes taken at the September 13 and 14 Mission Techniques meetings and the September 20 Lunar Abort meeting, all on the C’ mission. This list is far from complete. Basically, these items are only the changes and additions to the material…
Correction to memorandum
Please destroy the cover page of memorandum 68-PA-T-172A, dated July 26, 1968 and replace it with the attached corrected copy….
Propulsion system to be used on the “D” Mission Rendezvous CSI Maneuver
One of the planned rendezvous maneuvers (CSI₁) on the “D” mission is nominally zero. Since it is intended to make this maneuver based on the real time situation, some logic must be established to govern when and how the maneuver would be made. This memo is to describe the proposed logic….
Results of the February 18 Apollo Spacecraft Software Configuration Control Board (ASSCCB) meeting
This is just a short note to inform you of the most significant actions taken at the subject meeting….
Results of the June 11 Apollo Software Configuration Control Board (ASCCB) meeting
Today’s meeting was short and sweet – nothing particularly controversial. It started out with a discussion of the Stage Verify discrete. As noted it my last memo on this subject, program changes have been approved for Luminary such that the LGC completely ignores the Stage Verify discrete. Apparently we have generated enough concern that some…
D Rendezvous Mission Techniques Meeting – September 9, 1968
On September 9, we had another D Rendezvous Mission Techniques meeting. Basically what we did there was to discuss the new, simplified rendezvous mission plan and its effect on the work we have done so far. Based on this discussion, I am revising the ground rules and working agreements and will send them out within…

At the June 14 “D” Rendezvous Mission Techniques meeting, I unofficially (I guess) assigned at action item to your people who were there. Specifically, we asked for MIT’s recommended procedure for adjusting the W-matrix during rendezvous navigation in both the LGC and CMC. As a matter of fact, I understand that your people intend to…
VHF range shouldn’t be limited by software
Reference is made to the attached memorandum from Colonel Frank Borman. The 327 n.m. limit on the VHF ranging system appears to be a software constraint. I think it is due to the wau they scale the range. Would you people please check and see if we would be better off to change the scaling…
Visit to RCS, Camden, New Jersey, May 3, 1968
I visited RCA, Camden, New Jersey on Friday, May 3 to review an engineering model demonstration of the VHF Ranging System. The test setup included the components for the Command Module (CM) and the Lunar Module (LM) located in two adjacent screen rooms. Signal strength between the two installations could be varied by changing a…
