The International Satellite Communications System (ISCS)
The United States will continue to support ICAO/WMO requirements (as a servicing World Area Forecast Center - WAFC) with the ISCS.
The global coverage will continue to span approximately from 105degrees east longitude to 65 degrees east longitude (covering the Pacific Ocean, Atlantic Ocean, North America, Central America, South America, and the Caribbean).
The remainder of the world coverage will continue to be supported by the WAFC located in the United Kingdom through their satellite broadcast system called SADIS (which primarily covers the European, Asian, and African continents as well as the Indian Ocean).
PACIFIC OCEAN REGION (POR)
The POR portion of ISCS will be centered around the WorldCom shared Master Satellite Hub in Yacolt, Washington.
The Yacolt Master Satellite Hub will be linked via a 64 Kbps terrestrial (redundant) circuit to the WorldCom shared Master Satellite Hub in Andover, Maine.
All ISCS WAFS data originating at the NWSTG will transmitted, using TCP/IP network protocol, to the Yacolt facility (via the Andover facility) for broadcast to all POR sites.
REGION IV METEOROLOGICAL TELECOMMUNICATIONS NETWORK (RMTN)
The RMTN portion of the successor ISCS will be centered around the WorldCom shared Master Satellite Hub, in Andover, Maine.
The Master Satellite Hub will be linked via a 64 Kbps terrestrial (redundant) circuit to the National Weather Service Telecommunications Gateway (NWSTG) in Silver Spring, Maryland.
All ISCS data originating at the NWSTG will be transmitted, using TCP/IP network protocol, to the WorldCom Andover facility for broadcast to all ISCS RMTN sites.
All RMTN sites will uplink their data at 2.4 Kbps, using TCP/IP network protocol, to the NWSTG (via the WorldCom Andover facility) for inclusion as part of the collective that is broadcast to all ISCS RMTN sites.
