SATOPS MORNING REPORT – August 21, 2000

A further precautionary power down was made on early Saturday morning
to replace a board in the UPS.  Operations were briefly handed over
to the backup sites (CDAs and ESOC) between 0013Z and 0020Z and the swap
was accommodated without incident.  There were no impacts to products.

POES

No change in the status of the POES spacecraft.

On Friday August 18, at 1813Z, the NOAA-15 AVHRR channels 2, 4, and
5 were re-enabled after being disabled for almost 24 hours as part of scheduled
contingency testing.  An expected temperature decrease of the instrument
baseplate was observed without a noticeable decrease in the scan motor
operating current.

On Friday, August 18,  NOAA-12 rev 48115:  G3A, L1B, L5B:
Not recoverable from IMUX system.  The LAC playbacks were not recoverable
due to recorder management; 100% of G3A was recovered on rev 48117.

On Friday, August 18,  NOAA-12 rev 48116:  G4A, L3B, L2A,
L1B:  Not recoverable from IMUX system.  The LAC playbacks were
not recoverable due to recorder management; 100% of G4A was recovered on
rev 48117.

On Sunday, August 20, NOAA-15 rev 11802:  93.5% of G1A recovered
due to playback while spacecraft was fading.

On Sunday, August 20, NOAA-11 rev 61395:  85% of STIP4B was recovered
due to a brief problem with the ground system at FCDAS.

POES operations were nominal over the past 72 hours.

DMSP

No change in the status of the DMSP spacecraft.

DMSP operations were nominal over the past 72 hours.

GOES

No change in the status of the GOES spacecraft.

At 1201Z on Friday, August 18, GOES-8 frame breaks were observed and
attributed to loss of signal synchronization.

Between 1100Z and 1110Z on Friday, GOES-10 E/W address errors were observed
on the SPS.  Problem rectified at the CDA by 1110Z; lost 14 lines
of the 1100Z image as a result.

At 1728Z on Friday, a GOES-10 frame break was observed and attributed
to address phasing error.

At 2001Z on Friday, a GOES-10 frame break was observed and attributed
to loss of signal synchronization.

At 0448Z and 0607Z on Saturday, GOES-10 frame breaks were observed and
attributed to high BER and address phasing error, respectively.

At 1110Z on Saturday, a GOES-8 frame break was observed and attributed
to BER at the CDA due to a crop duster in the area (!).

At 1159Z and 1209Z on Saturday, additional GOES-8 frame breaks were
observed and attributed to high BER.

At 1330Z and 2303Z on Saturday, GOES-8 frame breaks were observed and
attributed to address phasing error.

At 0753Z, 0806Z and 0826Z on Sunday, GOES-8 frame breaks were observed
and attributed to high BER at the CDA.

At 1419Z on Saturday, a GOES-10 frame break was observed and attributed
to command I/O error.

At 2003Z and 2015Z on Saturday, GOES-10 frame breaks were observed and
attributed to address phasing error.

At 2025Z on Saturday, a GOES-10 frame break was observed and attributed
to loss of signal synchronization.

At 0418Z and 0520Z on Sunday, additional GOES-10 frame breaks were observed
and attributed to high BER.

At 1027Z on Sunday, a GOES-8 frame break was observed and attributed
to high BER.

At 1302Z, 1616Z, 1811Z and 2053Z on Sunday, GOES-10 frame breaks were
observed and attributed to high BER at the CDA.

At 0153Z and 0614Z on Monday, GOES-10 frame breaks were observed and
attributed to high BER at the CDA.

At 0503Z on Monday, a GOES-10 frame break was observed and attributed
to loss of signal synchronization.

Normal pre-eclipse battery reconditioning activities continue.

GOES operations were nominal over the past 72 hours.
