Why the transition to EMWIN-N:

 

Changes in the next series of GOES satellites, the GOES-N thru P constellation, have necessitated development of EMWIN-N. Sometime before 2011 the current GOES satellites will be removed from operation and will be replaced by the new series. This will allow for the use of improved technologies, but all current EMWIN users will need to migrate due to frequency, power and modulation changes.

 

Coming Improvements Include:

• Data rate is doubled to 19.2 Kbps - More data!

• Forward error correction - Greater reliability

• Increased use of compression - More data!

• Enhanced data stream - Including regional Nexrad images

• Dedicated transponder

• No eclipse seasons

Transition Details:

There are currently two GOES-N series satellites, GOES 13 and 14 in orbit and awaiting full time operations.  Once they are placed into service the EMWIN-N broadcast will replace the current legacy broadcast. 

Although subject to change, the current plans are for:

• GOES 13 to replace GOES 12 (East) in May 2010
• GOES 14 to replace GOES 11 (West) in December 2011

The transition could occur earlier due to premature failure of one or both of the current GOES satellites. All users should consider migrating to EMWIN-N capable systems.  Please see the vendor page on the EMWIN website.   Anyone with an EMWIN-N system can try out the broadcast by using either the GOES 10 or GOES 14 satellite.  Both are providing a test broadcast until December 2009, when the GOES 10 will be removed from service and GOES 14 will be placed into storage.
