7.2 Static and dynamic vessel data
There are two categories of information transmitted by a transceiver: static
and dynamic data.
The vessel's dynamic data, which includes location, speed over ground
(SOG) and course over ground (COG), is calculated automatically using the
integrated GPS receiver.
Static data is information about the vessel which must be configured into the
AIS transceiver. This includes:
● Maritime Mobile Service Identity (MMSI)
● Vessel name
● Vessel call sign (if available)
● Vessel type
● Vessel dimensions
In most countries the operation of a transceiver is included under the vessel's
marine VHF license provisions. The vessel on to which the AIS unit is to be
installed must therefore possess a current VHF radiotelephone license which
lists the AIS system, vessel Call Sign and MMSI number.
