GMT
Greenwich Mean Time. See also UNIVERSAL TIME COORDINATED.
GPS SYSTEM TIME
Time corrected to Universal Time Coordinated (UTC) and used as the time standard by the user segment of the GPS
system.
HEADING
The direction in which the vessel is pointed, expressed as angular distance from north clockwise through 360 degrees.
HEADING should not be confused with COURSE. The HEADING is constantly changing as the vessel yaws back and
forth across the course due to the effects of sea, wind, and steering error.

INTERFACE
Electronic circuits that permit the passage of data between different types of devices; For example, the speed and
heading interface circuit permits data from a speed log and compass to pass to the navigator processor.
IP
Internet Protocol (
IP ) is the central, unifying protocol in the TCP/IP suite. It provides the basic delivery mechanism for
packets of data sent between all systems on an internet, regardless of whether the systems are in the same room or on
opposite sides of the world. All other protocols in the TCP/IP suite depend on IP to carry out the fundamental function
of moving packets across the internet.
ITDMA
Incremental Time Division Multiple Access -Access protocol for pre-announced transmissions of temporary or non-
repeatable character. It is also used during data link network entry.
ITU
International Telecommunication Union.
LED
Light Emitting Diode.
LSS
Logical AIS Shore Station. A LSS is a software process, which transform the AIS data flow associated with one or
more PSS into different AIS-related data flow. The SW process of a logical AIS station can run on any appropriate
computer at any appropriate place.
