1.5 AIS – Automatic Identification System
AIS is an identification system that uses VHF communication to
transmit and receive AIS data. AIS operates primarily on two
dedicated VHF channels, AIS 1 – 161,975 MHz and AIS 2 – 162,025
MHz. Where these channels are not available regionally, the AIS can
be set to alternate designated channels.
The AIS mobile station broadcasts the vessel's position, speed and
course over ground as well as static and voyage related information.
Short safety related text messages can be sent between vessels or
broadcast from shore based AIS stations or Aids to Navigation like
buoys and lighthouses. The on-board installed mobile station is
designed to operate automatically and as a stand-alone unit. When not
transmitting, the mobile station listens for position information from
other vessels or shore based stations.

Seatex AIS 100 Instruction Manual, rev. 5 General information

Figure 1 Elements in an AIS system
The system broadcasts data using the SOTDMA (Self-organised Time
Division Multiple Access) data protocol. Each minute is divided into
4500 time slots, enabling simultaneous transmission of up to 500
stations.
Coverage
The system radio coverage range is similar to other VHF applications
and is dependent on the height of the antenna. The propagation differs
from that of a radar, due to the longer wavelength, so it is possible to
"see" around bends and behind islands if the landmasses are not too
high. A typical value to be expected at sea is 20 nautical miles.

AIS information content
AIS type of information is exchanged automatically between vessels,
vessels and shore based stations and vessel and Aids to Navigation
like buoys and lighthouses. The information transmitted by the AIS
mobile stations is grouped in four categories:
Static Data
•MMSI (Maritime Mobile Service Identity) number
•Call sign and name
•IMO number
•Length and beam
•Type of ship
•Location of position fixing antennas on the ship
Voyage Related Data
•Ship's draught
•Hazardous cargo type
•Destination and ETA (at Master's discretion)
Dynamic Data
•Position with accuracy indication and integrity status
•Time in UTC
•COG (Course over ground)
•SOG (Speed over ground)
•Heading
•Navigational status
•Rate of turn
Safety-related Messages
•Reading and writing short safety related messages
Data reporting and transmission rates
AIS data as stated above is autonomously sent at different update rates
and thus reporting rates are dependent on the ship's navigational
mode. Dynamic information is dependent on speed and course
alteration while static and voyage related data are transmitted every 6
minutes or on request. Thus fast ferries will report their navigational
data at a higher update rate than ships at anchor.

Type of Ship Reporting
Interval
Ship at anchor 3 min.
Ship 0 to 14 knots 12 sec.
Ship 0 to 14 knots and changing course 4 sec.
Ship 14 to 23 knots 6 sec.
Ship 14 to 23 knots and changing course 2 sec.
Ship > 23 knots 3 sec.
Ship > 23 knots and changing course 2 sec.
All data input to the AIS mobile stations is based on the NMEA 0183
data protocol. Messages sent on VHF are based on the AIS data
protocol, which defines several Message Types containing different
types of information.
1.6 System components
The Seatex AIS 100 system consists of the following units:
Figure 2 AIS 100 system components

Seatex AIS 100 Instruction Manual, rev. 5 General information
7
AIS 100 Minimum Keyboard and Display (MKD)
The MKD unit provides a simple user interface to the mobile station.
The keypads on the MKD can be used to navigate between dedicated
menus used for configuration and display of vessel navigation data.
Text messages can also be entered into the MKD and transmitted to
other vessels or shore based AIS stations providing warnings or other
relevant navigation information. Thus the MKD provides basic
presentation of configuration data, position data and text messages. If
the AIS has been interfaced to the on-board ECDIS system or radar
the information displayed on the MKD can also be displayed on an
AIS compatible ECDIS or ECS systems.
AIS 100 mobile station
The mobile station incorporates two VHF receivers, configured to
operate on the predefined AIS frequencies for the region, one VHF
transmitter transmitting on all required frequencies and one DSC
receiver. The mobile station also incorporates a GPS receiver and a
processor. The internal GPS receiver, which is capable of receiving
differential corrections for increased position accuracy, is used for
time synchronisation and as a backup position sensor. For AIS data
transmission, the Self Organised Time Division Multiple Access
(SOTDMA) data protocol is used. SOTDMA enables a large number
of vessels to receive and transmit AIS data at the same time.
Front LED indicators
The LED indicators on the front of the mobile station can be used to
monitor status as well as data reception and transmission.

AIS 100 connection box
The connection box is used to connect to external sensors main
position sensor, heading sensor and rate of turn sensor (when
available). These sensors are mandatory while interfaces to electronic
hart systems and long range communication systems, are optional.
AIS compatible ECDIS/ECS systems are interfaced to the AIS
through serial line communication. Power is supplied to the AIS
mobile station through the connection box.
AIS 100 VHF antenna
The VHF antenna is used for VHF communication. The antenna is
connected to the mobile station using cables with attenuation less than
3 dB.
AIS 100 GPS antenna
The GPS antenna is an L1 antenna receiving signals from all visible
satellites. The antenna is hermetically sealed and the cable used to
connect the GPS antenna to the mobile station should be of a quality
that ensures minimum loss of signal, i.e. less than 20 dB.

2OPERATION
2.1 Introduction
The AIS should always be in operation. It is recommended not to
switch off the AIS during port stays in order to provide information to
port authorities. In areas where piracy occurs, the master may switch
of the transmitter. If the transmitter is switched off, static data and
voyage related information will be stored.
2.2 Operational modes
After the unit has been installed and configured it operates
automatically without any user intervention. The mobile station has
three operational modes:
•Autonomous and Continuous mode
•Assigned mode
•Polled or Controlled mode
2.2.1 Autonomous and continuous mode
In the Autonomous and Continuous mode the mobile station
automatically defines its own reporting rate in accordance with its
navigational mode, speed and course. The unit also selects its own
data transmission slots. This is the normal mode for operation in all
areas but the mode may be switched to/from Assigned mode or Polled
or Controlled mode by a competent authority via a base station on
shore.
2.2.2 Assigned mode
A competent authority responsible for traffic monitoring may
remotely set transmission intervals and/or time slots for the vessel
mobile station. When operating in Assigned mode, the mobile station
will transmit position data on a slightly different format, AIS Message
Type 2, instead of the transmitted AIS Message Type 1. In Assigned
mode the mobile station does not change its reporting rate when
changing course and speed. Assignments are limited in time and will
be re-issued by the competent authority when needed. Thus, Assigned
mode only affects the transmission and not the reception of position
reports.

Seatex AIS 100 Instruction Manual, rev. 5 Operation
10
2.2.3 Polled or controlled mode
In this mode the mobile station will automatically respond to
interrogation messages from a ship or competent authority. The
response is transmitted on the channel where the interrogation
message was received. Operation in Polled or Controlled mode does
not conflict with operation in the other two modes.
2.3 Malfunction and fallback arrangements
The mobile station has built-in integrity testing to continuously verify
own operational status and notify user and external equipment if any
malfunction is detected. Part of this test monitors the transmitter and
receiver modules. Alarm status will be transmitted to the PI port in
addition to triggering the alarm relay.
Malfunction type Malfunction source
Tx malfunction
ID 001 Tx frequency is not locked or Tx power is measured outside setting
SWR 3:1 malfunction
ID 002 SWR is measured to more than 3:1
ChA malfunction (RX1)
ID 003 ChA frequency is not locked
ChB malfunction (RX2)
ID 004 ChB frequency is not locked
Rx DSC malfunction
ID 005 Ch70 frequency is not locked
2.4 Mobile station initialisation
The mobile station will automatically switch on when power is
applied to the unit by connecting the power cable in the connection
box. There is no on/off switch and thus power is removed by
disconnecting the power cable in the connection box.
•After power has been applied, wait for the two-minute
initialisation period.
•At completed initialisation all LEDs will go amber.
•The mobile station is ready for operation when the GPS LED is
blinking at one-second intervals.
•The View page will appear on the MKD.
