1. INTRODUCTION TO AIS
The AIS Automatic Identification System was conceived as an element of radio communication
to improve the safety and efficiency of Maritime Navigation
The AIS system is designed to operate in one of the following modes:
- Collision prevention.
- Identification of ships and goods by the coastal authorities.
- Port traffic management tool.
WHAT IS AIS?
It is basically a digital radio system that uses
various instruments and sensors as inputs.
These entries are processed and transmitted in
accordance with international standards that
have been accepted for the exchange of
information.
This process is carried out without intervention
from the crew.
The AIS is also capable of transmitting small
messages to other ships or base stations by the
crew as a free text for information exchange.

USER MANUAL MTU AIS-C Page 3
Rv01
1.1. PURPOSE OF AIS.
The AIS system allows all ships that equip it to exchange information about navigation. This data
can help other ships plan their routes and increase safety. Allows you to include AtoN navigation
aids by equipping them with AIS equipment as part of the navigation environment.
The data that can be exchanged is divided into three categories:
STATIC
DYNAMIC
TRIP
IMO number
Coordenadas UTC
Draft
Number
Course
Dangerous goods
Sleeve and longing
Speed
ETA / Destination
Type of boat
Navigation status
Route
GPS antenna position
Rudder
Turning speed
Static information is programmed manually, the dynamics are obtained from the ship's sensors
and the travel is regularly updated by the crew during the trip.
As the AIS transponder is a VHF data communication, it allows to identify other ships behind
obstacles that with the use of radar would not be seen, and thus be prevented before a visual
contact.

USER MANUAL MTU AIS-C Page 4
Rv01
1.2.SHIP TO EARTH INFORMATION.
In coastal waters, local authorities can set up an AIS network to monitor boat traffic through
their waters.
These Base Stations can simply monitor AIS information in VHF and can also send messages to
AIS transponders installed on ships. The data they can obtain includes name and license plate of
the ship, destination, ETA and cargo information. In addition, these base stations emit messages
with weather and tide information.
AIS systems record and record all received information so that it can subsequently be
reproduced in the event of an accident. The AIS is used in rescue operations, allowing to
coordinate and monitor the movements of the ship.

USER MANUAL MTU AIS-C Page 5
Rv01
1.3.VESSEL TRAFFIC SYSTEMS VTS
AIS information integrates with VTS systems and provides a powerful tool to monitor ship
movements in the port areas. The combination of the use of Radar and AIS on a single VTS
display provides very reliable and accurate information, especially in areas outside radar range.
1.4.HOW DOES AIS WORK?
The AIS system can work in three ways:
- Standalone or continuous mode.
- Assigned mode.
- Interrogation mode.
Standalone or continuous mode.
In this mode the AIS transponder transmits your position information freely until it enters the
buffer of an AIS base station or other ship. At this point they both synchronize their AIS
computers and remain in this state until they communicate with any other AIS drive.
Assigned mode.
In this mode the base station assigns a slot to each AIS transponder within its action area and
defines the refresh rate of the data.
Interrogation Mode
The AIS transponder provides position information and other data when questioned by another
ship or base station.
BASIC COMPONENTS.
The basic components that allow the operation of an AIS transponder are:
2 TDMA receivers
1 receptor FDMA.
1 trasmisor TDMA
1 microprocessor.
1 interface with navigation sensors.
1.5.FREQUENCIES AND AIS TRANSMISSION.
The internationally defined AIS frequencies for use in maritime traffic are:
AIS 1 = 161,975 MHz
AIS 2 = 162,025 MHz.
AIS transponders can work at different frequencies, within the same band. The working
frequencies are defined regionally by the competent national authority.
The AIS can be controlled by DSC (digital selective calling) to move to another frequency with a
bandwidth of 25 KHz.

USER MANUAL MTU AIS-C Page 6
Rv01
1.6.THE SOTDMA PROTOCOL.
The AIS system employs for communications a self-organized time-division protocol that has
been inherited from air navigation.
This protocol allows a transponder to quickly integrate into a data network via radio along with
other equipment without interference or data collisions.
The protocol also allows communications between terminals in the same way as it is done on
GSM telephony networks.
The protocol has a 60s window with 2250 slots and includes 256 bits in each slot.
Each AIS unit has 2 receivers and a transmitter that can transmit in both AIS1 and AIS2 bands as
shown in the figure.
This transmission format allows data refresh up to a maximum speed of 2 seconds, spreading
half the stream load on each channel. This allows simultaneous ship-ship and ship-to-land
communications.
The coverage and distance of communications will depend on the transmission powers (usually
12W on ships and between 2 and 12 W in AtoN); and antennas and their location above MSL sea
level.

USER MANUAL MTU AIS-C Page 7
Rv01
1.7.DATA REFRESH SPEED.
Navigation information is updated to other ships and base stations according to navigation
needs so that no further information is generated than necessary in AIS channels.
The recommended refresh rate for the data is:
TRANSPONDER CLASS A (SINGLE SHIPS)

Boat anchored or moving at less than 3 knots

Boat between 3 –14 knots

2. DESCRIPTION OF MTU-AIS-C
The MTU-AIS-C transponder is an AIS-AtoN in an IP 67 watertight box, which provides automatic
information about the GPS position of the maritime signal; facilitating the location and
identification of buoys, beacons and headlights on the nautical chart of an AIS base station on
the ground.
This universal MTU device can send status signals and alarms from any type of beacon, rotating
or flashing ones, without the need for additional sensors.
Additionally, it can transmit meteorological and oceanographic data, such as current, wave
height, tides, and wind direction and intensity; all this with minimal energy consumption.
The MTU AIS Transponder meets IMO, IEC, ITU and IALA requirements.
2.1. AIS AtoN TYPE 1.
Type 1 transponders are transmitter-only devices and do not have a radio receiver. They can
work only using Fixed Access Time Division Multiple Access (FATDMA) mode. This working mode
requires a fixed slot for transmission.
2.2. AIS AtoN TYPE 3
Type 3 transponders are transmitter and receiver devices. They can work using FATDMA (Fixed
Access Time Division Multiple Access) mode or RATDMA (Random Access Time Division Multiple
Access) mode.

4.4. VHF ANTENNA CONNECTOR.
The VHF antenna connector is a female 'N' type connector.
It is recommended to use a coaxial cable type RG213 or similar with a maximum length of 30m
to minimize power losses.

The total average consumption will depend on the configuration used and the messages
transmitted periodically.
IMPORTANT NOTICE
The GPS antenna must be active type with 3.3V and must be electrically isolated from the VHF radio
connector otherwise it may cause damage to the AIS.

USER MANUAL MTU AIS-C Page 17

•VSWR < 2.0
•Impedance 50 Ohms
•Minimum power 12.5 Watts
•Gain 1dBi to 6dBi
4.8. INSTALLING AND CONNECTING A GPS ANTENNA

minimum characteristics must be used:
•1575.42MHz center frequency for GPS.
•Active gain antenna at least 20 dB
•Power supply 3.3V
•Impedance 50 Ohms
IMPORTANT: The GPS antenna and its coaxial cable must be isolated from the support
structure and VHF radio connection
