NOAA GOES SATOPS Morning Report 2 May 2001

POES

No change in the status of the POES spacecraft.

NOAA-14 rev 32655 / F at 1421z on May 1: GAC5B received noisy
from the spacecraft with 99% of the expected data
recovered. This data would not archive on PACS using Frame Synch
2 or the Frame Synch 3 / TCS2 combination.

NOAA-11 rev 64981 / W at 1528z on May 1: STIP4B would not archive
on PACS using Frame Synch 1 or the Frame
Synch 3 / TCS2 combination. Engineers were present during the
transfer to observe the data archive attempts.

NOAA-14 rev 32660 / W at 2230z on May 1: LAC1B received noisy
from spacecraft with 97.8% of the expected data
recovered. No retransmittal required.

NOAA-15 rev 15425 / F at 0414z on May 2: GAC3B received noisy
from spacecraft on initial attempt due to loss of auto
track. The crew executed manual commands to stop and forward play
GAC3B for recovery: 100% recovered.

NOAA-11 rev 64991 / F at 0806z on May 2: STIP1A would not archive
on PACS using Frame Synch 1 or the Frame
Synch 3 / TCS2 combination.

Engineers continue to investigate the archive data problems which
may be related to the new POES Frame Synchronizers. (
Three new General Data Products (GDP) frame syncs were installed
on April 16). Performance and data quality is being
closely monitored.

POES operations were nominal over the past 24 hours.

DMSP

No change in the status of the DMSP spacecraft.

DMSP operations were nominal over the past 24 hours.

GOES

No change in the status of the GOES spacecraft.

GOES-2 De-orbit – After almost 24 years of operation (since
launch on June 16, 1977), the GOES-2 satellite is being
de-orbited via a series of maneuvers scheduled for May 1-5.
GOES-2 is being de-orbited due to low fuel conditions
on-board the spacecraft. The first two maneuvers took place on
Tuesday, May 1, and by all preliminary indications, were
nominal. At this point, it is assumed that the orbital perigee
has been raised to 50 km above the geosynchronous altitude.
Additional ranging data will be collected throughout the day
today to verify maneuver performance. Four additional maneuvers
are planned to raise the GOES-2 orbit 300 kilometers above the
geosynchronous altitude. The de-orbit maneuvers are being
executed from the Kokee Park Geophysical Observatory station in
Hawaii in coordination with the SOCC.

At 1114z on May 1, and at 0206z and 0309z on May 2, GOES-8 image
frame breaks were observed and attributed to loss
of signal synchronization..

The next phase of the GOES-9 Filter Wheel testing began today.
The Sounder Electronics was turned On at 1630Z, and
wideband data was collected for 3.5 hours, from 1800Z to 2130Z.
The Sounder and Filter Wheel appeared nominal from the
observed data. The Sounder Electronics will remain On for the
tests. A data package will be distributed by EMOSS
engineering today.

GOES operations were nominal over the past 24 hours.
