I verified with NOAA that the difficulties they had Friday and Sunday with
NOAAPORT were not actually due to interference with "zombiesat"--that
interference is due to occur next week.

Subject: Re: Galaxy-15 interference
Jeff,
The outages were direct results of preparing for the Galaxy-15 interference
with SEC-1.
The interference is still projected to take place between 12/12/10 and
12/18/10.
Thanks,

Hello, I write weather blogs for wunderground.com, a popular weather web
site. I'm planning on writing a post about the Galaxy-15 bird, and was
wondering whether the outages we experienced on Sunday and Friday were
actually due to interference from Galaxy-15, or whether they were due to
ground station operators preparing for the anticipated interference? It
sounds to me from the message below that we haven't begun to experience
interference from Galaxy-15 yet.
Thanks,

WHAT: SBN / NOAAPort Potential Satellite Interference ? NOTICE 1
WHEN: 12/13/10 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 12/13/10 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,
