Introduction

3.1 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 GPS or GLONASS 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, they 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.
This product is an AIS Aids to Navigation (AtoN) transceiver.

Introduction
3.2 System overview
This AIS AtoN is a self contained device supporting both Type 1 (transmit only) and Type 3 (transmit and
receive) operation. It is designed for installation in exposed locations on physical AtoN structures. The AIS
AtoN can be supplied with an optional sensor interface platform which interfaces to sensors (such as weather
instruments) and transmits measured data via AIS messages to surrounding vessels and shore stations.
The AIS AtoN has an exceptionally low power consumption making it suitable for installation on floating Aids
to Navigation with solar charged power systems. The lowest power consumption is achieved when operating
as a Type 1 AIS AtoN transmitting only position information. Further description of Type 1 and Type 3 operation
is provided below.
Figure 2 Typical AIS AtoN system
3.2.1 Type 1 AIS AtoN
A Type 1 AIS AtoN is a transmit only device using the FATDMA (Fixed Access Time Division Multiple Access)
access scheme. This requires that the AIS AtoN is configured with fixed AIS time slots in which it will transmit
AIS messages. Mobile AIS stations operating in the area where a Type 1 AIS AtoN is installed need to be aware
of the time slots allocated to the AIS AtoN. The slots allocated to the AIS AtoN are 'reserved' by AIS Base
Station transmissions covering the area in which the AIS AtoN is installed.
This mode of operation therefore requires that an AIS base station is operating in the same area as the AIS
AtoN and is configured to make the necessary slot reservations.
3.2.2 Type 3 AIS AtoN
A Type 3 AIS AtoN has transmit and receive capability and can therefore use either the FATDMA or RATDMA
(Random Access Time Division Multiple Access) access schemes. The RATDMA scheme allows the AIS AtoN
to internally allocate slots for transmission of AIS messages without reservation from an AIS Base Station.
AIS receive capability also allows a Type 3 AIS AtoN to be configured and queried for status via AIS messages
sent from a shore station (known as VDL configuration). An extension of VDL configuration is 'Chaining' where
configuration and query commands are passed along a 'chain' of AIS AtoN stations to a distant station beyond
the range of direct communication with a shore station.
3.2.3 GNSS systems
The AIS AtoN includes an internal GNSS receiver supporting the GPS system as standard.

Application
The transceiver uses message 6 to send
binary data (relating to connected
sensors and systems) to a specific shore
station. The transceiver can also receive
addressed binary messages for the
purpose of configuration and control.
This message is transmitted to
acknowledge receipt of a binary
message. The transceiver can also
receiver acknowledgements relating to
its own addressed binary transmissions.
The transceiver uses message 8 to
broadcast binary data (relating to
connected sensors and systems) to all
other AIS stations in range.
The transceiver can be configured to
transmit an addressed safety related
message to a specific shore station to
alert the operator to an off position,
vessel proximity or built in test failure
condition.

The transceiver receives message 13 in
acknowledgement of its transmission of
message 12.
The transceiver can be configured to
transmit a broadcast safety related
message to all AIS stations in range to
warn of an off position, vessel proximity
or built in test failure condition.
The transceiver can receive and process
DGNSS corrections provided from a
shore station using message #17. The
content of these messages can be used
to improve the accuracy of the on board
GPS receiver.

Application
When operating as a Type 3 transceiver
slot reservations made by a shore
station using message 20 will be
observed by the transceiver.
This is the primary message transmitted
by the transceiver. It contains the
position, identification and status of the
transceiver.
This message can be used for remote
(over the air) configuration of the
transceiver and configuration of a ‘chain’
of transceivers.
