NOAA GEOS SATOPS Morning Report 20 Feb 2001

SATOPS MORNING REPORT – February 20, 2001

POES

No change in the status of the POES spacecraft.

At approximately 1939Z,  the NOAA-15 MIRP rephasing function was
briefly re-enabled to temporarily re-synchronize AVHRR data to the MIRP. 
The command sequence was executed without event.

NOAA-14 rev 31621 / W at 0847Z on February 17 – Due to a ground system
issue (combiner needed to be recycled) all of GAC3A was lost, and only
67% of GAC5A was recovered.  Recorder management prevented replay
from spacecraft.

NOAA-14 rev 31653 / F at 1502Z on February 19:  Ran CP SEM_TED_LEVEL1
to reconfigure the TED as per procedure.

NOAA-14 rev 31654 / F at 1643Z on February 19:  After Antenna “C”
system problems were observed, the support was failed over to the “B” system
was accomplished and the S/C was successfully acquired.  Due to the
late acquisition, only 46% of the expected HRPT data was received. 
FCDA will troubleshoot the “C” system.

NOAA-14 rev 31656 / W at 1950Z on February 19:  GAC1A, the last
playback on the pass, was received noisy with 89% of the expected data
received.  Recorder management prevented replay from spacecraft.

NOAA-16 rev 2141 / W at 0606Z on February 20:  G3A was short (5.4%
recovered).  GAC3A was stopped incorrectly shortly after the record
cycle started on recorder 3A.  This GAC was cut short due to a GAC3B
stop and playback issued by the on-board schedule to playback data over
Svalbard for testing purposes.  An investigation is occurring to see
how this error made it past the schedule validation process.

POES operations were nominal over the past 72 hours.

DMSP

No change in the status of the DMSP spacecraft.

On F15/OPS 49 Rev 6135, a 99.75 playback (3990 S/C) second Cat 1 data
loss was declared.  A POGO site problem forced a reschedule through
BOSS.  BOSS was unable to acquire until late into the support time
due to turning around from another spacecraft.  Not enough time remained
to playback the smooth data resulting in Cat 1 time lines being violated.

On F13/OPS 47 Rev 30491, the SSMI BAPTA heater was turned on because
temperatures were down to -4.6 deg C.  The heater will remain on until
approximately March 20th.

DMSP operations were nominal over the past 72 hours.

GOES

No change in the status of the GOES spacecraft.

Battery reconditioning activities completed successfully over the weekend
for all spacecraft.

At 1914Z on February 16, a GOES-8 frame break was observed and attributed
to loss of signal synch.

At 1635Z on February 16, a GOES-10 frame break was observed and attributed
to loss of signal synch.

At 0423Z on February 17, a GOES-10 frame break was observed and attributed
to RFI (unknown source).

At 2034Z on February 17, a GOES-8 frame break was observed and attributed
to high BER (unknown reason).

At 1554Z on February 18, a GOES-8 CONUS image was missed due to an error
while reentering the schedule (after the 1547Z SMC upload for Boomsnap).

At 0453Z on February 19, a GOES-10 frame break was observed and attributed
to loss of signal synch.

At 1604Z on February 19, a GOES-8 frame break was observed and attributed
to RFI (unknown source).

At 0908Z on February 20, a GOES-8 frame break was observed and attributed
to high BER (unknown reason).

GOES operations were nominal over the past 72 hours.
