STEREO Weekly Meeting Minutes for 2007-07-17 (Week 29)


ANNOUNCEMENTS
-------------

* None.


INSTRUMENT AND SPACECRAFT STATUS
--------------------------------

* All subsystems on both spacecraft are nominal, except that the Ahead
  spececraft is currently operating on IMU #2.


DISCUSSION AND OPERATIONS CONSTRAINTS
-------------------------------------

Week 28

* Average daily downlink was 6.4 gigabits on Ahead and 7.0 gigabits on Behind.

* High gain antenna calibrations were performed on both spacecraft on day 192.
  The telemetry rate on Behind was reduced to 96 kbps during the calibration to
  avoid telemetry losses seen during the Ahead calibration.

* On day 194, during the Behind pass, the DSN had uplink failures from time to
  time.  This resulted in the stored command not being downlinked at the end of
  track, but no other problems.

Week 29

* Test of disabling usage of guide telescope data will be performed on both
  spacecraft on Wednesday, day 199.

Week 30

* There will be a momentum dump on Behind on day 206 at 19:00 UT.

Week 31

* The Phoenix launch is scheduled for this week.  The DSN schedules for the
  nominal launch window are in hand, but the contingency schedules have not yet
  been delivered.

* Current plans call for one pass per day on Ahead, and 12 passes over the week
  for Behind.

Other

* There was a discussion of the IMU disable test that occured on day 178.  The
  SECCHI team will collect data about the effect of this test on the instrument
  data, and report back to APL.
