Introduction
2Introduction
2.1 About AIS
The marine Automatic Identification System (AIS) is a location and vessel information reporting system. It
allows vessels equipped with AIS to automatically and dynamically share and regularly update their position,
speed, course and other information such as vessel identity with similarly equipped vessels. Position is derived
from the Global Positioning System (GPS) and communication between vessels is by Very High Frequency
(VHF) digital transmissions.
There are a number of types of AIS device as follows:
● Class A transceivers. These are designed to be fitted to commercial vessels such as cargo ships
and large passenger vessels. Class A transceivers transmit at a higher VHF signal power than class
B transceivers and therefore can be received by more distant vessels, and also transmit more
frequently. Class A transceivers are mandatory on all vessels over 300 gross tonnes on international
voyages and certain types of passenger vessels under the SOLAS mandate.
● Inland AIS stations. Similar to class A transceivers with additional features for use on Inland
waterways.
● Class B transceivers. Similar to Class A transceivers in many ways, but are normally lower cost due
to the less stringent performance requirements. Class B transceivers transmit at a lower power and at
a lower reporting rate than Class A transceivers.
● AIS base stations. AIS base stations are used by Vessel Traffic Systems to monitor and control the
transmissions of AIS transceivers.
● Aids to Navigation (AtoN) transceivers. AtoNs are transceivers mounted on buoys or other
hazards to shipping which transmit details of their location to the surrounding vessels.
● AIS receivers. AIS receivers receive transmissions from Class A transceivers, Class B transceivers,
AtoNs and AIS base stations but do not transmit any information about the vessel on which they are
installed.
The Protec-W transceiver is a combined Class A transceiver / Inland AIS.
Figure 1 The AIS network

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 GPS 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.

3.14 Long range messages
If the Protec-W transceiver is connected to a long range communication system via the long range
communications port then long range interrogations may be received. These are requests for information from
a distant base station beyond normal AIS operation range.
The Protec-W transceiver can be configured to automatically respond to Long range (LR) interrogations, or you
can opt to respond to any interrogation manually. Automatic response is the default setting, see section
for details of the menu option used to change this setting. Note that in automatic mode all requested information
is returned if it is available.
When a Long range interrogation is received you will be alerted by a notification screen as shown in Figure 19
(when automatic response is enabled) or Figure 20 (when manual response is enabled).
In automatic response mode simply review and acknowledge the notification screen using the ‘Acknowledge’
function key to return to the previous operating screen. In manual response mode you should review the
request and select either the ‘Respond’ or ‘Decline’ function key as appropriate.
