The GOES-12 is scheduled to be decommissioned on or about August 16, 2013. GOES-12 was launched on July 23, 2001, and it has supported South America at 60°W since May 2010. National Environmental Satellite, Data, and Information Service (NESDIS) announced the decommissioning on July 9, 2013.
The decommissioning will end the broadcast of the EMWIN-I legacy data stream. This broadcast was used to assist users in the transition to the EMWIN-N broadcasts on the operational GOES East and West satellites and facilitate manufacturer testing. Any remaining legacy users should migrate to EMWIN-N capable systems and use GOES East or West.
GOES 12 EMWIN-I users can also continue to receive EMWIN with an internet connection through the EMWIN ByteBlaster Network if unable to upgrade to newer equipment.
The EMWIN team continues to work with representatives from NESDIS, NASA, and the GOES R project team to develop the HRIT/EMWIN service. In the GOES R era, the EMWIN broadcast will combine with LRIT and become the HRIT/EMWIN broadcast. The data rate will greatly increase, to 400 kbps, allowing for a much larger product set.
Background: A prototype receiver has been developed and was tested using the GOES 14 satellite. The GOES 14 satellite (formerly known as GOES O) was launched on June 27, 2009 and became the second operational GOES N series satellite in orbit. The tests were performed at Wallops Command and Data Acquisition (CDA) station from August 24-27, 2009 and had positive results for both the EMWIN and LRIT data streams. The prototype provides backward compatibility to the current GOES generation broadcast to ensure transition flexibility. Additional enhancements have also been added since testing. The latest involves the design and testing of a low cost block down converter. We hope this design will lead to even lower costs.
The HRIT/EMWIN software defined radio receiver prototype documentation, source code and design documents are now available on the GOES R website.
