DATA MGT MESSAGE 11-10.05

TO  NOAAPORT USERS

FROM  RTH WASHINGTON DATA MANAGEMENT

SUBJECT  SBN/NOAAPORT POTENTIAL SATELLITE INTERFERENCE – NOTICE 1

EFFECTIVE DATE  12/12/10 TO 12/18/10 /FOR A PERIOD OF 2 TO 10 HOUR

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.

THE FOLLOWING PLAN IS BEING FINALIZED TO MITIGATE IMPACT TO OUR CUSTOMERS

1.    THE AWIPS SBN / NOAAPORT DATA WILL BE ROUTED AS USUAL FROM ANCF TO
        THE PRIMARY MASTER GROUND STATION /MGSL/ LOCATED IN HAUPPAUGE  NY
        VIA TERRESTRIAL COMMUNICATION LINES.

2.    THE HAUPPAUGE MGS WILL BROADCAST THE AWIPS SBN / NOAAPORT FEED
        THROUGH ANOTHER SATELLITE /TBD/ TO THE SES AMERICOM MGS IN HAWAII
        /11M/ANTENNA//.

3.    THE AWIPS SBN / NOAAPORT/  FEED WILL THEN REBROADCASTED THROUGH THE
        MGS IN HAWAII /9M ANTENNA/ TO SES-1 /TRANSPONDER 13C/ AND THEN
        DOWNLINKED USING THE CURRENT AWIPS SBN / NOAAPORT PARAMETERS.


NOTE  NO ADJUSTMENTS OR CONFIGURATION CHANGES TO THE AWIPS SBN WFO SITES OR
NOAAPORT CUSTOMERS EQUIPMENT WILL NEED TO BE MADE.  THE MGS IN HAWAII IS
OUTSIDE OF THE GALAXY 15 FOOTPRINT, MINIMIZING ANY RISK OF SATELLITE
INTERFERENCE TAKING PLACE BETWEEN GALAXY 15 AND SES-1 DURING THIS EVENT.


AFTER CONFIRMATION IS RECEIVED THAT GALAXY 15 CAN NO LONGER INTERFERE WITH
THE AWIPS SBN SATELLITE /SES-1/ WE WILL RETURN ALL SERVICES TO THEIR NORMAL
CONFIGURATION.

ADDITIONAL INFORMATION WILL BE PROVIDED REGARDING THIS POTENTIAL PROBLEM
AS MORE INFORMATION IS MADE AVAILABLE.

THANK YOU.
