NOAA GOES SATOPS Morning Report – May 9, 2003  Day 129 

DMSP 

All DMSP operations were nominal over the past 24 hours. 

POES 

NOAA-14 rev 43072 / F at 0443Z on May 9:  STIP3A on Mid S-Band (STX2) failed to obtain frame sync lock.  STIP3A was completely recovered on rev 43073. 

NOAA-17 rev 4530 / F at 0520Z on May 9:  GAC4B on Mid S-Band (STX2) failed to obtain frame sync lock on Ant. A.  CDA maintained a backup string (string 3) for the MSB resulting in successful recovery of GAC4B from string 3. 

All POES operations were nominal over the past 24 hours. 

GOES 

At 1356Z on May 8, a GOES-12 frame break was observed and attributed to loss of signal synchronization. 

At 1836Z on May 8, a GOES-10 frame break was observed and attributed to local weather-induced RFI (thunderstorms) at CDA. 

At 2055Z on May 8, the GOES-9 E/W and N/S compensation relays were opened.  These relays (actually four, commanded by one command) connect the North/South and East/West compensation signals to the imager and sounder.  Since the AOCE compensation signals are erroneous, this action basically disconnected the AOCE to instrument compensation interface.  The ground system has a backup mode capability to compute and add these Image Motion Compensation (IMC) signals to the imagery on the ground.  This is the current configuration and navigation of the GOES-9 imagery is essentially back within specification.  A change in the black body calibration procedure is being considered in an attempt to counteract the loss of on-board Mirror Motion Compensation (MMC).  An addition tiger team meeting will occur today at noon local to further
review options with NOAA, NASA, SS/L and ITT engineers. 

At 0342Z on May 8, a GOES-12 frame break was observed and attributed to local BER (unknown). 

GOES-8 continues its westward drift at 1.06 deg/day. 

All GOES operations were nominal over the past 24 hours.
