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. Gilbert 271 NOUS41 KWBC 231207 PNSWSH Service Change Notice 17-111 National Weather Service Headquarters Silver Spring, MD 707 AM EDT Mon Oct 23 2017 To: Subscribers: -NOAA Weather Wire Service -Emergency Managers Weather Information Network -NOAAPORT Other NWS Partners and NWS Employees From: Ronla Henry NWS AWIPS Program Manager 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.
