INTERNATIONAL SATELLITE COMMUNICATIONS SYSTEM
[attachment=61286]
GENERAL DESCRIPTION & PURPOSE
The ISCS is composed of two systems for data delivery via satellite communications. The first system is the World Area Forecast System (WAFS) in support of the International Civil Aviation Organization (ICAO) program for aviation data distribution. The WAFS broadcast makes globally available to aviation users
The second part of the ISCS is the Region IV Meteorological Telecommunications Network (RMTN) satellite system which replaced the two WMO Region IV GTS regional communication networks of the Antilles Meteorological (ANMET) and Central America Meteorological (CEMET).
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.
The Master Satellite Hub will be linked via a 64 Kbps 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.
