SUBJECT: AWIPS SBN STATUS UPDATE
.
THE AWIPS SBN IS CURRENTLY OPERATIONAL AND ALL
SBN DATA IS BEING BROADCAST TO AWIPS NATIONAL
WEATHER SERVICES OFFICES ON A TEMPORARY FREQUENCY.
THE AWIPS NCF MOVED ALL AWIPS NWS SITES TO A TEMPORARY
FREQUENCY ON SUNDAY DECEMBER 5TH AT APPROXIMATELY
2100Z DUE TO SBN INTERFERENCE PROBLEMS THAT WERE FOUND
ON THE ORIGINAL AWIPS SBN FREQUENCY.
.
THE SATELLITE PROVIDER HAS FOUND AND CORRECTED THE
SOURCE OF THE INTERFERENCE ON THE AWIPS SBN. NCF IS
CURRENTLY WORKING WITH THE SATELLITE PROVIDER,
GLOBECOM, ON ENSURING ALL INTERFERENCE PROBLEMS
HAVE BEEN CORRECTED BEFORE TAKING THE STEPS TO SWITCH
ALL AWIPS NWS OFFICES BACK TO THE ORIGINAL AWIPS SBN
FREQUENCY. ONCE A DATE/TIME HAS BEEN ESTABLISHED TO
SWITCH AWIPS SITES BACK TO THE ORIGINAL AWIPS SBN
FREQUENCY, ANOTHER AWIPS ADMIN WILL BE ISSUED. THE
SWITCH BACK TO THE ORIGINAL AWIPS SBN FREQUENCY FOR
NWS SITES WILL BE DONE REMOTELY BY THE NCF AND SITES
SHOULD NOT SEE ANY DOWNTIME AS A RESULT OF THE SWITCH
BACK TO THE ORIGINAL FREQUENCY.
.
AS A REMINDER, A RISK HAS BEEN IDENTIFIED WHEN THE
GALAXY 15 'ROGUE' SATELLITE TRAVERSES THE SES-1 ORBITAL
POSITION WHICH MAY RESULT IN A POSSIBLE LOSS OF DATA VIA
THE NWS AWIPS SBN / NOAAPORT FEED. THIS POTENTIAL
INTERFERENCE MAY TAKE PLACE BETWEEN 12/12/10 AND 12/18/10,
INCLUSIVE, ACCORDING TO OUR SATELLITE CONTRACTOR.
THE DURATION OF THE INTERFERENCE EVENT COULD BE
ANYWHERE FROM 2 HOURS TO 10 HOURS. WE ARE CONTINUING
TO RESEARCH AND ANALYZE THE FULL IMPACT AND RISK TO THE
AWIPS SBN / NOAAPORT PROGRAMS.
.
TEMPORARY AWIPS FREQUENCY = 1138.5
ORIGINAL AWIPS FREQUENCY = 1193.3
