Topic: GOES-12 to GOES-13 Transition Plan Update Message Issued: March 31, 2010, 1610 UTC Satellites Impacted: GOES-12 and GOES-13 Products Impacted: GOES-12 and GOES-13 Imager and Sounder Data and Associated Products including AWIPS, Ancillary services including DCS, LRIT, EMWIN, and SARSAT. Date/Time of Initial Impact: Pre-operational period begins 1/27/10, Operations begin 4/14/10 1934 UTC ----------------------------------------- Details: **This message provides an update of the date/time of switch, updated Eclipse and Stray Light Zone schedules, and resumption of GOES-13 pre-ops on 3/31** The Office of Satellite Operations/SOCC has provided the time of the GOES-12 to GOES-13 transition to be 1934 UTC on April 14, 2010. The Eclipse and Stray Light Zone schedules have been modified to include an extra day of Partial Frame testing, as well as continued GOES-11 Full Disk scans up until April 29, 2010. These updated schedules can be found at: http://www.ssd.noaa.gov/PS/SATS/eclipse.html (Users of NOAAPORT/GINI will continue to see GOES-11 Full Disk in place of the GOES-13 Partial Frames between 0430 UTC and 0545 UTC until 4/29/10) Partial Frame definitions and updated GOES-East schedules for GOES-13 can be found at: http://www.ssd.noaa.gov/PS/SATS/GOES/THIRTEEN/sched.html GOES-13 has resumed imaging/sounding and will switch back to the East schedule between 1941 and 2041 UTC on 3/31/10. --Original Notification-- ***GOES-13 is scheduled to replace GOES-12 as the GOES-East operational spacecraft on April 14, 2010 at 1934 UTC*** GOES-13, launched on May 24, 2006, is the first in the series of GOES-N satellites (GOES-14 was launched on June 27, 2009 and GOES-P is scheduled to be launched no earlier than March 4, 2010). This series will carry the 5 channel imager and 19 channel sounder similar to the GOES-I through M series, with some differences. GOES-13 carries the same imager and sounder payload as GOES-12, but the new spacecraft bus will allow it to operate through eclipse and most of the keep out zone periods and images will have increased navigation, registration and radiometric accuracy. (GOES-13 was used briefly as GOES-East in December 2008 during a thruster anomaly period with GOES-12). After GOES-13 becomes the operational GOES-East satellite, GOES-12 will be moved to 60W to support GOES-South America. The plans developed are intended to cause as few disruptions as possible to all users who need to acquire the GOES-12 GVAR signal via a ground receive antenna, while also allowing for the acquisition of GOES-13 GVAR data for 2 months prior to becoming operational to re-validate ingesting equipment and product generation.These plans are similar to the GOES-8 to GOES-12 transition plans in April 2003. An up to date synopsis: (1) On 2/23/10, The Office of Satellite Operations began the eastward drift of GOES-13 at approximately 0.5 degrees per day. Navigation elements can be found at NOAASIS ( http://noaasis.noaa.gov/NOAASIS/ ) or more specifically at: http://noaasis.noaa.gov/cemscs/navsum.txt . Daily longitudinal positions can be found at the end of this notification. (2) GOES-13 SXI was activated on 3/8/10 (3) On 4/14/10, GOES-13 will approach 81W. At 1934 UTC, GOES-13 GVAR and LRIT will be relayed through the GOES-12 downlink. Ancillary services (DCS, EMWIN, SARSAT) will remain on board GOES-12. GOES-13 will be declared GOES-East in the NOAA GOES Constellation. Users with fixed GVAR or LRIT antennae will not need to re-point to GOES-13. GOES-13 GVAR format is similar to GOES-12 (GVAR format change will occur with GOES-14 and beyond). (4) On 4/26/10, GVAR and LRIT downlinks will be switched from GOES-12 to GOES-13 when GOES-13 is at 75.5W. GOES-13 will stop drift. Ancillary services (DCS, EMWIN, SARSAT) will switch to GOES-13 at this time. Additional information about DCS transition can be found at: http://www.ssd.noaa.gov/PS/SATS/GOES/THIRTEEN/GOES-13_DCS_Notification.pdf (5) On 4/27/10, GOES-12 will begin eastward drift to 60W in order to replace GOES-10, which was de-orbited in December 2009. Imaging operations for GOES-South America will begin on or about 5/11/10. GOES-12 is expected to arrive on station at 60W on 5/17/10. Users of GOES data and products from ESPC: ESPC is ingesting GOES-13 GVAR and hosting it on McIDAS server West.nesdis.noaa.gov under the group GCR. In addition, OSDPD plans to re-validate product generation and distribution, including that of the GOES Ingest and NOAAPORT Interface (GINI). Product Area Leads will be responsible for coordinating with specific users on where they can obtain GOES-13 products. We will provide periodic updates to this transition plan as milestones are met, or any deviations from the schedule are anticipated.
