GOES 14 now broadcasting EMWIN


The EMWIN Broadcast from GOES-14 at 105 degrees West, has been activated and is currently available as an alternate to the GOES-East (GOES-13) EMWIN satellite broadcast signal.  The GOES 14 EMWIN broadcast will remain operational for six months and is scheduled to terminate on or about June 13, 2018. 
See SCN 17-120:  http://www.nws.noaa.gov/om/notification/scn17-120goes14.htm

This service is provided to extend the opportunity for GOES-13 users to continue using their existing EMWIN equipment and software beyond the GOES-13/16 transition in mid-December 2017; while acquiring and installing the new GOES-16 HRIT/EMWIN antennas, receivers and software. 

EMWIN data customers that transition to the GOES-14 EMWIN broadcast service are reminded that the downlink is a linear polarized signal.  Once the antenna has been properly oriented for azimuth and elevation, the receive feed may need to be adjusted for optimum reception.  This is usually accomplished by loosening the feed set-screw(s) and rotating the feed to achieve the highest signal strength on the EMWIN receiver.

HRIT/EMWIN Status


Here is an update from Seth Clevenstine, Direct Broadcast Manager.

Currently the GOES-16 HRIT/EMWIN broadcast is down due to a ground system anomaly that we're testing a fix for in hopes to have it up and running by next week. I'll post an update by the end of the week regarding the broadcast and it's status. I apologize for the delay in communication.

I would also like to take the time to point out the GOES East transition schedule.

Key Dates for GOES East Transition:
  1. November 30th, the HRIT/EMWIN broadcast will be offline while GOES-16 will transition eastward at 1.41 degrees a day
  2. December 11th, GOES-16 will stop it's drift at 75.2 degrees West.
  3. December 14th, ~1530Z GOES 13 will turn off the LRIT transponder
  4. December 14th, ~1545Z GOES 16 will turn on the HRIT transponder
  5. December 14th, ~1545Z, the HRIT ground system will start broadcasting to HRIT/EMWIN as the operational GOES East satellite.
