2/8 DAP expert: Marion Griffin x2307 SMS (RCS DAP) run (L, F). 1) on-orbit DAP: a best guess is that in -ZLV, with a 5[[degree]] deadband, PRCS would fire ~ once per minute. With a 1[[degree]] deadband, "several" firings per minute. VRCS, doesn't fire as often (more efficient for attitude hold) because "kick" (back into limit cycle phase plane) is smaller, less tendency to shoot through other side. SAMSO sim (JMF PDRS review) 1. procedures developed were Simfac peculiar (sim demonstrated feasibility). How would flight procedures be developed (since very specific visual cues are required) 2. Training for contingency ops is a major training impact. JMF estimates 8-10 runs in direct, & 8-10 more in back-up mode to get "proficient" at birthing/deploying payloads. What does this do to our Training time estimate for STS-2, STS-3? 3. The 45 timelines were "accurate" only in a relative sense (1.5-2.0 hours, roughly.... 3-4 times the nominal run). We need to do this
