This is big news, so I’m sending it across not only the NOAAport list, but the
LDM-users list as well.
In summary, the NWS is switching satellite providers for NOAAport, from
Satellite Environmental Services (SES) to Signal Mountain, a subcontractor of
Raytheon. What this means is that you will have to re-point your satellite
dish, from SES-1 located at 101 degrees west, to Galaxy 28, located at 89
degrees west, sometime in December through mid-January when the switchover
happens…right in the middle of winter. In any case, G-28 is an older satellite,
launched in 2005, where as SES-1 is only a few years old. G-28’s end-of-life
(EOL) is slated for 2020.
HughesNet satellite Internet, CBS and ABC, amongst other clients, also use this
bird.

Subject: Change in Satellite Broadcast Network
Effective on or about January 16, 2018
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.
