CGMS WG III Action 40.29
NOAA, in consultation with South America users and WMO, to investigate options for a follow-on to GOES-12 mission for South America, in order to develop a transition plan, involving GOES or other geostationary satellites, until the availability of the GOES next generation, which is expected to provide full coverage of both North and South America.

GOES-12 Operations HistoryGOES-12 as GOES East:• Launched on July 23, 2001• On-orbit storage at 105W from January 2002 through January 2003• Served as GOES East for 7 years starting April 2003• Lost propulsion system redundancy as a result of a B-string thruster fuel leak anomaly in
December 2008• Inclination maneuver fuel limitation reached in December 2009 • Replaced by GOES-13 in April 2010 when the orbit inclination was approaching 0.5 degrees.
GOES-12 as GOES South America:• Relocated to 60W longitude and began South America mission in May 2010. • Sufficient fuel remaining for E/W stationkeeping at 60W and de-orbit maneuvers. • Started XGOHI image remapping function in November 2011 when the orbit inclination
reached 1.75 degrees. • GOES-12 has supported South America for 3 years with Imaging and Sounding schedules

Status
• The GOES-12 satellite has provided over three years of successful GOES-12 coverage of South America on a best efforts basis.
• Increasing risk of operating GOES-12 due to low fuel levels and degradation of the spacecraft propulsion systems.
• Risk is increased during the eclipse season because the spacecraft cannot be maneuvered due to battery power constraints.
• NOAA must ensure safe deorbit of the spacecraft.

Decommissioning
• NOAA is planning to conduct the safe deorbit and decommissioning of GOES- 12 during the month of August before the eclipse season.
• All systems on the satellite will be shut down at that time.• End GOES-12 South America support on August 13, 2013• Reserve August 14, 15 for approved End of Life tests• Perform GOES-12 orbit raising maneuvers and complete
decommissioning on August 15 and 16

User Impacts to ending GOES-12 Operations• South American Users (primarily Brazil) make products out of GOES-12 data
including satellite derived winds – Brazil: Instituto Nacional de Pesquisas Espaciais (INPE)
• GOES-12 data used in numerical modeling. Primary source of weather products
– Argentina: Comision Nacional De Activadades (CONAE)• Limited utilization due to increased GOES-12 orbit inclination
– Argentina: Buenos Aires Volcanic Ash Advisories
• GOES-12 data is used by STAR Cooperative Institute for Meteorological Satellite Studies (CIMSS)
• OSPO/SPSD/SAB can access the data (from SSEC at Univ. of Wisconsin in McIDAS format) for use in viewing, analyzing, etc... This is done on rare occasion

GOES-12 vs. GOES-13South America Coverage
GOES-12 Images Every 3 Hour:• 4 South America images during non Full Disk hours • 1 Full disk and 2 South America images during Full Disk hour• There are 11 S.A. images in the 3-hour period
GOES-13 Routine Schedule Images Every 3 Hour:• 2 Southern hemisphere images during non Full Disk hours• 1 Full Disk, 1 Southern hemisphere images during Full Disk hour• There are 6 S.A. images in the 3-hour period
GOES-13 Rapid Schedule Images Every 3 Hour:• 1 Full Disk image during Full Disk hour• No other measurable data over South America• There are only 1 S.A. image in the 3-hour period
OSPO to analyze the possibility of providing an image of South America every hour when GOES-13 is in Rapid Scan Operation

Conclusion• Although NOAA does not have specific plans to replace GOES-12, it will review
options should circumstances change and subject to the health of the total GOES constellation.
• NOAA is in the process of analyzing the possibility of providing an image of South America every hour when GOES-13 is in Rapid Scan Operation
• NOAA is mindful of the interests of South American users and will keep them, as well as WMO and CGMS, fully apprised of the status of prospects for follow-on GOES coverage.
• Full coverage of South America is expected through NOAA follow-on generation satellites beginning with GOES-R.
