NOAA GOES SATOPS Morning Report - August 5, 2003  Day 217 

Status Report From: National Oceanic and Atmospheric Administration
Posted: Wednesday, August 6, 2003

DMSP 

OPS48 rev 32680 R+07 from POGO-C 1356Z on August 4:  Executed SCCR 48-101, steps 1-4, to modify battery 1 charge timer limit on SCP 1 and 2. 

All DMSP operations were nominal over the past 24 hours. 

POES 

All POES operations were nominal over the past 24 hours. 

GOES 

A GOES-12 East/West maneuver will be conducted on Wednesday, August 6 at 0930Z. 

At 1157Z on August 4, a GOES-8 safety monitor alarm sounded indicating an illegal instruction was encountered on-board the spacecraft.  The Reprogram Branch function on-board the spacecraft was autonomously disabled as a safety feature on the spacecraft.  At 1430Z, engineering restored the illegal instruction counter and performed other commanding subsequent to the event.  At 2230Z, operators started a full processor dump to continue the fault analysis.  (The dump was performed in three parts to accommodate the Fairbanks 13-meter C X-band command tests.)  Reprogram remains disabled as it is not currently needed since GOES-8 is in a non-imaging status. 

At 2052Z on August 4, a GOES-10 image was missed due to a late start on the daily SCC upload, partly as a result of operational impacts with the other GOES spacecraft. 

At 1515Z on August 4, a GOES-12 frame break was observed and attributed to loss of signal synchronization. 

At 2146Z on August 4, a GOES-10 E/W maneuver was successfully executed. 

At 0836Z on August 5, a GOES-9 frame break was observed and attributed to RFI (unknown).

GOES-8 continues its westward drift at 1.06 deg/day.  The drift table with the estimated current position can be found at  http://www.oso.noaa.gov/goes/GOES-8_Drift_Table.txt.  GOES-8 will be stopped at 165E on or about August 24.
