SATOPS Morning Report – March 26, 2003  Day 083

DMSP 

FBKS reports that DMSP supports are driving the ant to past limits resulting in a system failure. 
This problem has been written up in the past.  MPSS supports have been scheduled from horizon to horizon with no regard to masking.  FBKS operators have deleted all DMSP supports thru 16Z J086 and re-added so to incorporate the masking.  Staff notified and will address open DIR’S on this anomaly. 

48/30818/12/FBKS-B&A/2142Z:  Ant. ‘B’ failed; Fairbanks crew reinitialized it – it failed again.  Fairbanks crew added up and initialized ant. ‘A’.  SOCC crew failover to A; all data recovered.  GOOD JOB by ALL 

Sys2 operational, as of 0032Z.

All other DMSP operations were nominal over the past 24 hours. 

POES 

CEMSCS emergency IPL today:  1513Z – 1625Z Xfers suspended in interim. 

FBKS reports Barrows T1 line down hard at Barrows.  Ticket open but service is expected to be down until morning. 

N-15/25280F/1607Z:  HRPT was received nominally by the CDA and 100% at SOCC.  CEMSCS requested a post-pass transfer of the data from the IMUX.  Unfortunately, the IMUX had only recorded 959 frames of the expected 3706 frames received (39%), so that was all that could be transferred to CEMSCS. 

All other POES operations were nominal over the past 24 hours. 

GOES 

GOES operations were nominal over the past 24 hours. 

Eclipse operations for all spacecraft continue.  Eclipse schedules for GOES-8 and GOES-10 (which can be used to track the day-to-day image deletions due to KOZ and eclipse) can be found at:

GOES-12 remains in a test phase, in normal on-orbit mode, drifting at an eastward rate of ~0.33 degrees per day toward the GOES-East position where it will replace GOES-8 in April.  Routine SXI imaging is proceeding along with SXI test exposures.  At 1807Z on March 21, the GOES-12 schedule was suspended for magnetometer testing.  The normal imaging schedule was resumed at 1926Z on March 21. 

GOES-9 is currently at approximately 178.4 E drifting at a westward rate of ~0.723 degrees per day toward 155 E longitude where it will support the GMS-5 replacement mission in April. 

Major upcoming GOES milestones (Note: These dates are subject to change!) 

• April 1:  GOES-12 becomes operational GOES-East for imaging/sounding at 1815Z
• 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
