See list belowSEP 7 196767-PA-T-76APA/Chief, Apollo Data Priority CoordinationAnother meeting about trajectory control on the first manned Apollo mission (S/C 101)

1. As you may have heard, we had the first of the Trajectory Control Data Priority Panel meetings last Thursday, August 31. My original intent was to go through the four major exercises on the Spacecraft 101 mission involving the Guidance & Propulsion Systems at that meet- int but time did not permit discussion of more than the SPS maneuvers and rendezvous. As a result, I have set up a followup meeting on Thursday, September 14, in Room 660, Building 2, at 9:00 a.m. to finish that. The two mission exercises I expect we will spend most time on are: (a) retrofire and reentry and (b) earth landmark track- ing and navigation. In addition, if the guidance systems performance data is available as requested last time, we will also go over that to evaluate its impact on selection of guidance modes and monitoring procedures for the SPS maneuvers.

2. I hope your organization can participate in this discussion, which I look upon as being for information exchange more than for decision making. Hopefully, we will all get a thorough understanding of how these various things are to be done and how the systems are to be utilized.
