NOAA GOES SATOPS Morning Report March 31, 2003 Day 090

DMSP

OPS49 rev 17021 R+02 from POGO-C at 0600z on March 30:  POGO equipment problem at rise (lost their tech bus).  After reinitializing site equipment, there was not enough time to bring necessary fine (TL) data down.  Cat 1 data loss declared.  5932 s/c  secs and 148.30 p/b secs.  Recovered data on rev 17022 from HULA-A at 0717z.

POES

NOAA-16 rev 12986 / F at 2334z on March 30:  A 13-meter antenna issue caused LAC1A, LAC3A, LAC2A, and LAC3B transfers to be delayed for over one hour (until after the next N-16 pass).

NOAA-11 rev 74854 / W at 0246z on March 31:  Both STIP2B and STIP4A from the previous NOAA-11 pass could not be recovered from the IMUX, due to a bad EOF marker.   STIP2B could not be replayed from the spacecraft due to recorder management.  STIP4A was replayed during this pass and 100% of the data was recovered.

GOES

At 1805z on March 28, the GOES-10 DSN telemetry transmitter B (2208 downlink) to dwell mode, as per SCP, to support TACTS testing at Fairbanks.   The DSN transmitter was commanded back to normal mode at 1905z. The TACTS testing at Fairbanks was a success.

At 2026z on March 29, a GOES-10 frame break was observed and attributed to loss of signal synchronization.

At 2114z on March 29, a GOES-10 frame break was observed and attributed to E/W address error.

At 0123z, 0149z, 0219z, and 0232z on March 30, multiple GOES-8 frame breaks were observed and attributed to high BER due to weather at CDA.

A lightning strike at WCDAS at 0234z on March 30, affected voice links, prime T1 and multiple antennas.

Between 2355z on March 29 and 0532z on March 30, multiple GOES-10 frame breaks were observed and attributed to high BER due to weather at CDA  The observed frame break times were 2355z, 0119z, 0123z, 0131z, 0146z, 0152z, 0203z, 0215z, 0223z, 0230z, 0245z, 0509z and 0532z.

At 1252z on March 30, GOES-8 telemetry lock was briefly lost and the schedule suspended.  The 1301z CONUS image was lost due to the inability to command.  The WCDAS switched GOES-8 antenna service to the 18M ‘A’ antenna.

GOES-12 remains in a test phase, in normal on-orbit mode, drifting at an eastward rate of ~0.33 degrees per day toward the GOES-East position where it will replace GOES-8 tomorrow, April 1, between 1800 and 1815z.   Thanks to GOES-8 for almost 9 years of great support!!

GOES-9 is currently at approximately 173.3 E drifting at a westward rate of ~0.720 degrees per day toward 155 E longitude where it will support the GMS-5 replacement mission in April.

Eclipse operations for all spacecraft continue. Eclipse schedules for GOES-8 and GOES-10 (which can be used to track the day-to-day image deletions due to KOZ and eclipse) can be found at:  http://www.oso.noaa.gov/goes/koz-eclipse/koz-eclipse.htm

Major upcoming GOES milestones (Note:  These dates are subject to change)

• April 1:  GOES-12 becomes operational GOES-East for imaging/sounding at 1815z
• April 15:  GOES-9 removal from storage
• April 16-19:  GOES-9 GVAR begins, INR startup with a 0.7 deg/day drift
• April 22:  GOES-12 stops at 75 deg W; ancillary communication services (DCS, WEFAX, EMWIN, SAR) become operational.
• April 24:  GOES-8 drift start westward from 75 W
• April 25:  GOES-9 drift stop at 155 E
