PACS SVR38/9 Nov 2007 Commissioning Phase2 Overview and Constraints Launch and Early Orbit Phase (LEOP) –Duration 110min. (formal end = 2 nd orbit correction on day 12) –From ground disconnection to separation from launch vehicle –Orbit corrections (day 2, day 12) –Ground station coverage ~22h per day (few days) Commissioning (spacecraft and instruments in parallel) - Telescope heating (days 0 - ~22) - Cryo Cover opening (~day 30, Telescope around 120K) - Ground stations: New Norcia (3h) + Kourou(2h), but probably not contiguous - Data rate limitations for Kourou <=150kbit/s real time - PACS to assist in Telescope - Startracker boresight calibration - ICC operations will be conducted primarily at MOC with online support by

PACS SVR38/9 Nov 2007 Commissioning Phase3 Preparation Status (1) Plan discussed and agreed within PACS ICC First draft Plan delivered on 31-July-07 Second draft in progress: –Separate specialist meetings to settle open issues: Optimum bias determination and curing strategy of Ge:Ga detectors for FPG Optimum bias determination for bolometers for FPG (TBD) FPG strategy (TBD) –Documentation via dedicated system level test procedures –Separate technical notes for open issues –Converted real-time procedures into MOIS (done for FDIR, SFT, Chopper; Grating on hold because of open SCR)

PACS SVR38/9 Nov 2007 Commissioning Phase4 Preparation Status (2) Baseline operations are planned via MPS and MTL All manual procedures must be delivered via the PACS User Manual and attached MOIS import files. ftp://ftp.mpe.mpg.de/people/pacs/PACS_User_Manual/PACS_ ME-UM-002_drft4r_User_Manual_binder.pdf  IUM update (MOIS conversion) towards Issue 1 in progress

PACS SVR38/9 Nov 2007 Commissioning Phase8 Next Steps and Open Work –Expect now feedback from HSC/Project on our commissioning phase plan input –Continue with details and completion strategy (who does what) and create small dedicated teams (calibrators, specialists, commanders) [Ge:Ga bias, bolometer bias and FPG teams] –Awaiting TN from project what PACS is expected to do for STR vs. Telescope alignment measurements –Convert SFT/IST scripts into Engineering Observations –Convert grating procedure into MOIS (SCR pending) –Release issue 1 of IUM with updated manual procedures –Get training on “Expert HSPOT” and MPS
