SATOPS Morning Report 16 Apr 2001

SATOPS MORNING REPORT April 16, 2001

No significant effects noted on any spacecraft from continued
elevated solar/geomagnetic activity. All observed effects have been noted in the past and
have not resulted in adverse conditions on the spacecraft. Additional
information on the current state of the space environment can be observed on: http://www.sec.noaa.gov/today.html

POES

No change in the status of the POES spacecraft.

The CPU-A CIU Timing Fix flight software patch for NOAA-16 was
successfully uploaded and enabled last Thursday, April 12. Ephemeris was loaded to CPU-A during rev 2882/W at 1834z on April 13. Performance of the
CPU over the weekend was nominal. CPU-A performance will be monitored for a period of time before it is re-enabled as a viable backup to CPU-B.

NOAA-14 rev 32426 / W at 0913z on April 15 – G2B was noisy with
97.6% of the expected data transferred to CEMSCS. 100% of data recovered on rev 32428
at 1137z.

NOAA-11 rev 64758 / F at 2036z on April 15 – Post-pass, only 76%
of S4B was found to be recorded on the IMUX ground recorder.

POES operations were nominal over the past 72 hours.

DMSP

No change in the status of the DMSP spacecraft.

After a failed POGO pass for OPS47 at 1607z on April 13 (due to a
ground system failure at the site), FAIR was configured and the spacecraft was acquired at
1614z. An ephemeris load, star load, and three data sets were all
successfully completed within time constraints.

After a failed POGO pass for OPS 45 1610z on April 14 (due to
site not receiving spacecraft data that was played back and subsequent commanding problems),
the data was recovered on the next rev at 1758z at FAIR.

DMSP operations were nominal over the past 72 hours.

GOES

No change in the status of the GOES spacecraft.

GOES-8 East/West station keeping maneuver #34 is scheduled for
Tuesday, April 17 at 2001z. The commanded thruster firing duration will be 7.0
seconds. GOES-10 will provide full disk imaging for approximately 2 hours
during the GOES-8 maneuver period.

At 1804z on April 13, the primary West propulsion line heater,
oxidizer tank heater and fuel tank heaters were turned off as per normal post-eclipse season procedure.

At 1306z, 1510z and 1901z on April 13, GOES-10 frame breaks were
observed and attributed to address phasing error..

At 0222z, 1125z and 1822z on April 14, a GOES-10 frame break was
observed and attributed to RFI (reason unknown).

Between 1242z and 1248z on April 14, the GOES-10 schedule was
suspended due to bad telemetry due to a ground receiver drop out. The imager was stuck
in start and the 1244z PACUS was missed as a result. The receiver was swapped out and
the schedule resumed at 1250z.

Between 1347z and 1355z on April 15, GOES-10 X-Ray sensor channel
flagged out of limits high.

To review the imaging schedules for the GOES-8 and GOES-10
spacecraft, refer to: http://www.ssd.noaa.gov/SSD/GOES/eclipse.html to identify images
canceled to satisfy instrument keep-out-zone (KOZ) requirements.

GOES operations were nominal over the past 72 hours.
