-------- Original Message -------- Subject: ADMIN NOTICE NOUS72 KNCF Date: Mon, 6 Dec 2010 12:13:02 -0700 From: Unidata Local Data Manager <ldm@xxxxxxxxxxxxxxxx> To: ldmnotices@xxxxxxxxxxxxxxxx 907 NOUS72 KNCF 061912 ADMNCF 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 . NCF/SEG
