SMOV Status & Planning Meeting Notes
6/08/09
Notes provided by Burley (richard.j.burley@nasa.gov), Biagetti (biagetti@stsci.edu, and others as
indicated.
- Summary
Spacecraft subsystems continue to operate nominally. Aft-shroud
temperature continue to be monitored closely. Parts 3 and 4 of the COS FUV high-voltage
ramp-up continues according to plan. All internals are looking good. The third FGS AMA
adjustment (S-curve optimization) has been accomplished and analysis is underway. The
ACS Tiger Team has convened in order to determine what response might be needed to the
observed anomalous output drain voltage (Vod) in the WFC. STIS MAMA FUV recovery is
complete and nominal.

rates, relative to ground testing

FGS/OTA
 The 3rd FGS2R2 AMA Move (Ops Request 18497) was executed
158/22:30–22:39. The subsequent ITS test for move verification is scheduled
to take place 159/02:14-02:25 with only partial coverage by R/T telemetry.
The R/T TLM should include the ITS FL and part of the LOS scan. I’ll be
sending a follow-up report after this has been executed and analyzed.
• S-Curves of Target ‘A’ in any of the 3 positions (1, 5 & 8) we’ve been
using for AMA move definition aren’t scheduled until Position 1
at159/16:10 (06/08 ~ 12:10 EDT).
• This won’t have R/T TLM coverage.
• Goodrich personnel will be evaluating the 15 POL data (159/14:51 –
160/21:20), and reporting to the SMOV morning meeting no earlier
than Wednesday, 06/10.
• “I extend my thanks to the FOT staff as well as the Goodrich
personnel that supported this evening’s efforts.” DCrain
 Analysis of the ITS test, executed 159/02:23-02:27, has been completed.
The change in the ITS FL position was 1.386 a-s (X) and 2.285 a-s (Y).
 All hardware nominal, 1 HSTAR submitted #11869, the FGS 3 problem
Guide Star again, could not maintain the star in Coarse Track. Resulted in
Fine Lock Back-Up on FGS 1. 4 succeeding Acquisitions using this same
star were all successful (eventually) in Fine Lock.
 There were 15 successful Acquisitions, including the FL BU. 1 Acquisition
awaits ETR telemetry.
 There was an ITS observation following the AMA move #3.
 Predicted ITS FL position change was 1.2 asec in X and 1.5 asec in Y.Actual
ITS FL position change was 1.386 asec in X, 2.285 asec in Y.
 For the Mini-Alignment (11458), all Astrometry in Real-time was good,
waiting for the ETR telemetry.
• First FGS2R2 fine lock!
 HSTAR 11867 plan to close to a double (weak correlation), failed Walkdown,
then could not maintain Coarse Track on the second try.
 Up-coming 24 hours:
• 4 GSACQs, 4 Reacqs and the 15 POL Proposal.
• First FGS 1 Servo Maintenance will occur at 159:15:44:32, before
the Reacq.

complete OPUS support schedule for SMS
091597C2 (SA159T03) for next week.
 Thanks very much to Mike Boyer, Fang Peng and
Leah Evans for working to make this happen on


HSTAR 11865 MSIDs; are not unique, and never have been. Tag-IDs; are
unique, always have been (carryover of old SATS/IED system).
• MNEUMONIC STRING ID (says unique in ICD-26) It has broken
CLong’s trending tool. STScI believed/believes these were
permanent.
• Changes were required for ACS-R.
o PRD release letter does not include MSIDs – so it could
be easy to miss.
o Communication was not provided to/from STScI
• Actions;
o BBurkhardt will provide list of changes between PreACS-R database and current database.
o RDeyton will provide Tag-ID/MSID mapping.
o CLong will provide ACS-R SMOV schedule risk
assessment.
HSTAR; 11873, CCS Limit discrepancy. Tjacintho says investigation
underway.

PACOR: BPatel
 From June 7 (8am) to June 8 (8am), Pacor-A received one event with fasttrack observations.
• The data was processed and delivered to OPUS without any
problems.
o
OPUS
 We processed the new schedule for week 159 with no apparent problems,
and we now have our database populated with the required observation
records.
 Continuing to fast-track science data, with more data for COS proposal
11356 coming tonight.
 Making changes to some OPUS calibration s/w.
• This part of OPUS is not covered in the Freeze Plan.
