The U.S. National Weather Service (NWS) is pleased to be a partner with you in a coordinated effort with the Federal Aviation Administration (FAA), the International Civil Aviation Organization (ICAO), and World Meteorological Organization (WMO) to expand and improve the telecommunications service, weather prediction, and weather planning capability in the region. Our combined efforts in meteorological and aviation services, ICAO and the WMO exemplify the excellent cooperation and effective teamwork that have accomplished so much since the ISCS system began.

     The contract for the current system (ISCS-G2) will expire 31 December 2009. As of that date, the United States will no longer broadcast ISCS meteorological and aviation weather products via the ISCS-G2, but will use the ISCS-G3 to broadcast ISCS products. Planning is underway for the transition to the ISCS-G3 from the current ISCS-G2. A contract for the ISCS-G3 will be awarded by early 2009. The ISCS-G3 will provide improved performance compared to that of the current system. No resources will be required of your site personnel to complete the transition of your site. We are working with your workstation provider on the ISCS-G3 connection requirements for your existing ISCS workstation. A detailed transition schedule will be posted on this web page as soon as it is available. After award of the contract for the ISCS-G3, we will be posting advisory bulletins on this web page to keep you advised on the progress of the transition.

     Our sincere appreciation to you for your continuing support and assistance as we approach the 2009 implementation and operational phases of the new ISCS-G3 and the phase-out of the ISCS-G2 network.
