NOAAPort Satellite Change

2023-02-07T13:55:00.004-06:00

Subject: Updated: Change to NOAAPort/Satellite Broadcast Network (SBN), Effective in Early 2023

Updated to include a change to the Receive Site Transition Window Start date and the RF Frequency.

The NWS was notified by its current satellite vendor of their intention to realign the NOAAPort/SBN/NWWS service from the Intelsat Galaxy 28 satellite to the Galaxy 31 satellite.

The NWS has coordinated with its current satellite service vendors to mitigate impacts for all NOAAPort/SBN/NWWS customers. This includes activating a dedicated dual illumination period with the Galaxy 28 and the Galaxy 31 satellites to aid customers in transitioning to the newly designated NOAAPort/SBN satellite.

The NWS will continue to provide transition updates as additional information becomes available. The transition schedule follows below:

GoesTools Receiver Interface

2020-12-26T22:18:00.004-06:00

Work is almost completed on our GoesTools satellite receiver interface. GoesTools is used to receive the HRIT/EMWIN satellite data stream.

GoesTools runs on a Raspberry pi. A new application for the Raspberry pi has been written to serve data to the Windows pc. This application also interfaces to a Nextion 3.5" display to show receiver stats.

This is a picture of the Nextion Raspberry pi screen.

To help with alignment, you can click on the Vitribi number to see a larger screen.

A new ingest program has been created to allow Weather Message to receive data from the Raspberry pi.

The Raspberry pi and display are installed in the following case.

This makes for a nice and clean installation.

GOES 14 now broadcasting EMWIN

2017-11-28T09:19:00.000-06:00

The EMWIN Broadcast from GOES-14 at 105 degrees West, has been activated and is currently available as an alternate to the GOES-East (GOES-13) EMWIN satellite broadcast signal. The GOES 14 EMWIN broadcast will remain operational for six months and is scheduled to terminate on or about June 13, 2018.
See SCN 17-120: http://www.nws.noaa.gov/om/notification/scn17-120goes14.htm

This service is provided to extend the opportunity for GOES-13 users to continue using their existing EMWIN equipment and software beyond the GOES-13/16 transition in mid-December 2017; while acquiring and installing the new GOES-16 HRIT/EMWIN antennas, receivers and software.

EMWIN data customers that transition to the GOES-14 EMWIN broadcast service are reminded that the downlink is a linear polarized signal. Once the antenna has been properly oriented for azimuth and elevation, the receive feed may need to be adjusted for optimum reception. This is usually accomplished by loosening the feed set-screw(s) and rotating the feed to achieve the highest signal strength on the EMWIN receiver.

HRIT/EMWIN Status

2017-11-15T06:37:00.000-06:00

Here is an update from Seth Clevenstine, Direct Broadcast Manager.

Currently the GOES-16 HRIT/EMWIN broadcast is down due to a ground system anomaly that we're testing a fix for in hopes to have it up and running by next week. I'll post an update by the end of the week regarding the broadcast and it's status. I apologize for the delay in communication.

I would also like to take the time to point out the GOES East transition schedule.

Key Dates for GOES East Transition:

November 30th, the HRIT/EMWIN broadcast will be offline while GOES-16 will transition eastward at 1.41 degrees a day
December 11th, GOES-16 will stop it's drift at 75.2 degrees West.
December 14th, ~1530Z GOES 13 will turn off the LRIT transponder
December 14th, ~1545Z GOES 16 will turn on the HRIT transponder
December 14th, ~1545Z, the HRIT ground system will start broadcasting to HRIT/EMWIN as the operational GOES East satellite.

For further information on next month's GOES East transition plans, please see the following website:

GOES-16 Drift and Transition to Operations

2017-10-25T14:15:00.003-05:00

GOES-16 is planned to begin drifting to the GOES-East operational location of 75.2 degrees west longitude on November 30, 2017. Drift is scheduled to complete on December 11, 2017 and nominal operations will resume by December 20, 2017. During the drift period, five instruments (ABI, GLM, SUVI, SEISS, and EXIS) will be placed in safe or diagnostic modes and will not be capturing or distributing data. MAG is the only instrument that will continue to operate with nominal data distribution during the transition. GOES Rebroadcast (GRB), Data Collection System (DCS), High Rate Information Transmission (HRIT)/ Emergency Managers Weather Information Network (EMWIN), and the Search and Rescue Satellite-Aided Tracking (SARSAT) system will be disabled during drift. This is due to X-band radio frequency downlink interference.

On December 7, 2017, GOES-13 GOES VARiable (GVAR) service will begin relay through GOES-14 and will be available through both satellites until December 14, 2017, at which time GOES-13 GVAR will only be transmitted through GOES-14. GOES-13 GVAR users will need to repoint their antennas to 105 degrees west to maintain receipt of GOES-13 data. Once GOES-16 reaches 75.2 degrees west on December 11, 2017, there will be three to nine days of calibration activity. All instruments will resume nominal operations by December 20, 2017, and GOES-16 will officially become GOES-East. There will be a period of overlap with GOES-13, which will remain at 75 degrees west, after GOES-16 becomes GOES-East. GOES-13 will remain on and provide data until January 2, 2018, at which time it will begin drifting to its storage location at 60 degrees west. During this period of overlap, GOES-13 GVAR will be relayed through GOES-14. Additional information will be communicated as needed.

All drift and transition operations will be led by the NESDIS Office of Satellite and Product Operations (OSPO) with GOES-R Program operational support. Final scheduling of drift operations may change based on operational needs and will be a NOAA-level decision.

Change in Satellite Broadcast Network

2017-10-23T07:51:00.000-05:00

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.
