NOAA SATOPS Morning Report April 3, 2003 Day 093

DMSP

All  DMSP operations were nominal over the past 24 hours.

POES

All  POES operations were nominal over the past 24 hours.

GOES

At 1819z on April 1, a GOES-12 frame break was observed and attributed to loss of signal synchronization.

GOES-12 will continue to drift at an eastward rate of ~0.33 degrees per day toward 75 degrees W until the stop maneuver is performed on approximately April 22.  Until GOES-12 arrives on-station, the GOES-12 will be retransmitted via GOES-8 (to minimize impacts to the users).

GOES-9 is currently at approximately 171.2 E drifting at a westward rate of ~0.717 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-East and GOES-West (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 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

All GOES operations were nominal over the past 24 hours.
