The EMWIN team will participate in the NOAA 2013 Satellite Conference in College Park, Maryland. We plan to have demonstrations and be available to answer questions related to EMWIN and the combined HRIT/EMWIN service for GOES R. The conference will be held from April 8 -12, 2013.
GOES 12 at 60 degrees is nearing end-of-life. The satellite currently is broadcasting the EMWIN-I legacy data stream. NESDIS has yet to set an exact date for GOES 12 to be removed from service, but it is expected to occur in the fall of 2013. Any remaining legacy users should migrate to EMWIN-N capable systems and use GOES East or West. For transition details click here. Please see our vendor page for EMWIN vendor listings.
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.
