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.The AWIPS SBN / NOAAPort data will be routed as usual from ANCF to the 
Primary Master Ground Station (MGS) 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,
