Introduction
2.2 Static and dynamic vessel data
Information transmitted by an AIS transceiver is in two categories: 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 internal GNSS receiver.
Static data is information about the vessel which must be programmed into the AIS transceiver. This includes:
● Maritime Mobile Service Identity (MMSI)
● Vessel name
● Vessel call sign (if available)
● Vessel type
● Vessel dimensions
2.3 AIS operation licensing
In most countries the operation of an AIS transceiver is included under the vessel's marine VHF licence
provisions. The vessel on to which the AIS transceiver is to be installed must therefore possess a current VHF
radiotelephone licence which lists the AIS system, vessel Call Sign and MMSI number. Please contact the
relevant authority in your country for further information regarding ship's radio licensing requirements.
