2.1 Static and dynamic vessel data
There are two categories of information transmitted by an AIS device: 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 GPS receiver. Dynamic data is not transmitted by AIS AtoN’s.
Static data is information about the vessel or Aid-to-Navigation which must be programmed into the AIS device. This includes:
• Maritime Mobile Service Identity (MMSI)
• Vessel or AtoN name
• Vessel call sign (if available, not relevant to AtoN’s)
• Vessel or AtoN type
• Vessel or AtoN dimensions
In most countries the operation of an AIS AtoN device will require the local authority to grant an operating license and MMSI number.
An MMSI number is required in order for the AIS device to operate. The product requires an AtoN specific MMSI number with
the format 99*******. Please contact the relevant authority in your country for more information.
