NATIONAL WEATHER SERVICE MARINE PRODUCTS VIA U.S. COAST GUARD AIS Broadcast
Beginning September 11, 2008, the Tampa Bay Cooperative Vessel
Traffic Service began broadcasting Automatic Identification
System (AIS) test messages to select test participants in the
area via standard AIS channels. These broadcasts—originating
from MMSI 003660471—are less than ½ second in duration,
and, should not impact other AIS users in the area. However,
should they, please notify the U.S. Coast Guard's AIS
Problem Report or by calling the U.S. Coast Guard's Navigation Information
Service (NIS) watchstander at (703) 313-5900.
This is the first phase of a Coast Guard Research & Development
Center project to develop, design and evaluate the most efficient
means by which mariners can receive critical real-time navigation
safety information through the use of AIS and its binary messaging
capability. The first phase of the project will directly access
Physical
Oceanographic Real Time System (PORTS) quality checked
data from National Oceanographic and Atmospheric Agency (NOAA)
servers, and, repackage it for AIS transmission. These broadcasts
will commence at 1100 on 11 September 2008 and every 6th minute
thereafter, i.e. 11:06:00 a.m., 11:12:00 a.m., etc.
Sometime mid-2009, testing will expand to include the broadcasts
of other critical navigation safety information, such as waterway
closures, wreck markings, high wind and/or low visibility
warnings, etc. The U.S. Coast Guard is highly optimistic that—in a not
to distant future—AIS binary messaging will extend beyond
CVTS Tampa Bay, to all other USCG
VTS and ultimately to most waterways within our Nation-wide
AIS (NAIS) network. For further information contact Irene
Gonin, USCG R&D Center, 1082 Shennecossett Road, Groton,
CT 06340 or Irene.M.Gonin@uscg.mil.
