For you satellite junkies, you've been following the saga of the
drifting, rogue Galaxy 15:

NOXX01 KWBC 291520
WHAT SBN NOAAPORT POTENTIAL SATELLITE
INTERFERENCE NOTICE 1
WHEN- 12 12 10 TO 12 18 10 FOR A PERIOD OF 2 TO 10 HOURS
INFO
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.
ROUTED AS USUAL FROM ANCF TO THE PRIMARY MASTER
GROUND STATION MGS LOCATED IN HAUPPAUGE,
NY VIA TERRESTRIAL COMMUNICATION LINES.
2.
AWIPS SBN NOAAPORT FEED THROUGH ANOTHER
SATELLITE TBD TO THE SES AMERICOM MGS IN HAWAII
11M ANTENNA.
3.
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.
