It might be worthwhile for you or your people to look into the DPS modelling in the RTCC. The “D” mission includes several maneuvers with manual throttling. Improper modeling of these burns may have some effect on the operation, although, offhand I would not think so….

Software for the AAP CSM spacecraft computer
The time appeared right to try to find out exactly what the program requirements are for the CSM computer for AAP and we had meetings on January 28 and 30 to do that. As a result of these meetings, a number of PCR’s will be prepared and submitted to the Apollo Spacecraft Software Configuration Control…
Notice of a catch-all Apollo 12 Mission Techniques meeting
We have scheduled a Mission Techniques meeting on Monday, September 15, 1969, to go over the Apollo 12 flight for the “last” time. Although most of the discussion will probably deal with the landing and rendezvous phases, we would like to clean up all open items regardless of mission phase….
Apollo 205/101 reentry procedures
ASPO’s Systems Engineering Division wrote a memo outlining general procedures to be used by the Spacecraft 101 crew following a G&N controlled deorbit burn and also specifying that an automatic reentry would definitely not be performed. You forwarded that memo to me questioning whether our Data Priority Coordination group had looked into this subject and,…
Progress Report – RTCC program development reduction – Review of requirements for the AS-502 mission
On February 17th we held a meeting in our continuing effort to reduce the program development demands on the Real Time Computing Complex. In this instance, a group of FCD, FSB and MPAD people reviewed requested modifications to the AS-501 RTCC program in preparation for the AS-502 mission. I could briefly summarize the results by…
Recommendation to retain the Two-Stage Lunar Orbit Insertion (LOI) Maneuver
This memorandum documents the results of our review of the two-stage LOI maneuver which you requested as a result of a recent OMSF suggestion that it might be preferable to return to a single burn plan. Participation in this review involved all operational elements of MSC concerned in this matter. The conclusions are unanimous….
External Delta V for LOI
In a December 15 memo (67-PA-T-121A), I indicated that we were going to perform LOI using two maneuvers. I also stated that pending results of some studies then underway we expected to use the External Delta V guidance mode for these maneuvers rather than Lambert steering. The primary reason for doing this was to make…
Mission D Maneuver Monitoring Document
Included in the D mission are some special propulsion and guidance system tests. They consist of unique maneuvers which are not discussed in either the Rendezvous or Entry Mission Techniques Documents. They required development of special mission techniques which are documented in the attached book….
Invitation for an AAP spacecraft computer program requirements shindig
On April 20 we had our first meeting to establish spacecraft computer program requirements for the AAP missions. Sufficient time will soon have elapsed to permit substantial progress on the action items issued at that meeting making it worthwhile to gather again. Accordingly, you are invited to attend such a meeting at 9:00 a.m., May…
