NOAA GOES SATOPS Morning Report – July 9, 2001
POES
NOAA-14 rev 33587 / F at 1435Z on July 6: GAC5B was noisy from
the spacecraft. Postpass transfer to CEMSCS revealed 35
gaps, no replay from the spacecraft is possible sue to recorder scheduling.
Because some noise was interpreted by the frame synch as legitimate data,
the quality report was corrupted and a final percent recovered was not
available.
NOAA-11 rev 65914 / W at 1600Z on July 6: Sent CMD PMCTL 3E7F
as per SCP to initiate Batt. #1 CS NOW (software
reset). NOAA-11 power management continues to be closely monitored
during this eclipse season. Control Center personnel
continue to monitor and advise staff of variances from nominal.
NOAA-12 switched to the Redundant Crystal Oscillator sometime between
July 1 and July 4 (limited contact with satellite
preclude exact determination of the time of the anomaly). On
rev 52697 / W at 2013Z on July 6, command RXOPR was sent as per SCP to
select the primary RXO.
NOAA-14 rev 33606 / W at 2230Z on July 7: LAC1A and LAC1B were
received noisy from spacecraft. 98% of LAC1A and
91.6% LAC1B was recovered. Neither of these data sets are recoverable
again, due to recorder scheduling limitations.
NOAA-14 rev 33615 / F at 1411Z on July 8: LAC3B was received noisy
from spacecraft with 96% of the expected data
recovered. CEMSCS indicated that they did not was a replay from
the spacecraft.
NOAA-14 rev 33623 / F at 0333Z on July 9: GAC5B was received noisy
from spacecraft with 94% of the expected data
recovered. GAC5B not recoverable due to recorder scheduling limitations.
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 1352Z on July 6, a GOES-10 frame break was observed and attributed
to CRC error.
At 1421Z on July 6, a GOES-10 frame break was observed and attributed
to high BER (unknown).
At 1820Z on July 6, a GOES-8 frame break was observed and attributed
to loss of signal synchronization.
At 2234Z and 2342Z on July 6, GOES-10 frame breaks were observed and
attributed to loss of signal synchronization.
At 0030Z on July 7, HR1 was selected as prime antenna for GOES8 OPS.
By 0047Z, command receiver ëBí was flagging yellow
high at approximately -99.0 dBm. CDA notified of problem and
installed an attenuator to bring signal strength more in line at
approximately -104 dBm. At 0050Z, CEMSCS called to inform that the
0045Z Northern Hemi was severely degraded. PM operator and Central
confirmed that they see the same degradation. The image degradation continued
with the 0101Z Conus. A switch to transmitter 2 made at 0107Z, command
receiver levels stabilized and the 0109Z Southern Hemi image was clear.
At 1934Z on July 7, a GOES-8 frame break was observed and attributed
to loss of signal synchronization.
GOES operations were nominal over the past 72 hours.
