Effective on or about January 16, 2018, the SES-1
satellite will no longer provide data to the NWS Satellite Broadcast Network
(SBN). Data will become available from the Galaxy 28 satellite (G-28) by early December, before discontinuing the
broadcast from SES-1. In addition, the location of the Master Ground Station
(MGS) will move to Holmdel, NJ; the Backup Master Ground Station (BMGS) will
remain in Fairmont, WV. These changes are a result of the transition to Signal
Mountain as the new NWS SBN communications support subcontractor under
Raytheon, the Prime Contractor for the Advanced Weather Interactive Processing
System (AWIPS).
The downlink antennas at all receiving site ground
stations (SGS) will need to repoint to G-28 to accommodate this
transition. Users should not need new equipment to continue receiving NOAAPORT
data once the antenna has been adjusted.
Important specifications are below:
Galaxy 28 Satellite Location (new): 89 degrees West FEC
Type: DVB-S2
Polarity: Vertical/Right
Band: High, C-Band
The changeover from SES-1 to G-28 will occur in several
phases to ensure a smooth transition that maximizes the amount of time with
satellite backup coverage. The date of the initial broadcast from G-28 is still
being finalized. Additional information and specific dates will be provided in
the coming weeks in the form of subsequent Service Change Notices.
If NOAAPORT users experience problems with service during
the satellite transition period, please contact James Calkins and Kevin Conaty
at NWS Headquarters.
