Points to cover:Points to cover:

• Who is True Heading?

• What is AIS – short presentation: What ships must have AIS today? Difference between Class A and Class B? Limitations.

• Who sets the standards?

• AIS regulations within 3 years.

• Pending AIS regulations.

• Who controls the compliance with the regulations?

TRUE HEADING AB (publ)TRUE HEADING AB (publ)

• Founded: March 2004

• Located in Stockholm, Sweden

• Experts within AIS technology

• Customers: Swedish Navy Swedish Maritime Administration Commissioners of Irish Light Trinity House Turkish Navy Hong Kong Marine Department Japanese Coast Guard And many more happy customers……


• The founders have been in committee work for the AIS standards :

IEC (International Electrotechnical Commission) ITU (International Telecommunication Union).

• Involved in development of the ITU standard 1371-4 (former 1371-1) => The base for the AIS standard

All the functional and technical requirements needed for AIS


• Members of IALA (www.iala-aism.org) => International Association of Marine Aids to Navigation and Lighthouse Authorities => Recommendations how AIS shall work and how to implement AIS functions.

• Members of CIRM (www.cirm.org) => COMITE INTERNATIONAL RADIO-MARITIME (CIRM)(The International Association for Marine Electronics Companies)=> Liaison group for Marine Electronic companies.

CIRM is one of the nine original international bodies accredited in 1949 as a non-governmental organisation in consultative status to the International

Maritime Organization (IMO).

What is AIS?What is AIS?• Automatic Identification System => Anti collision system

• The most extensive technical marine standard that has been developed in recent years.

• Today the following ships MUST have an AIS Class A transponderonboard according to SOLAS Chapter 5, regulation 19 -2.4:

All ships at international voyage over 300GT

All cargo ships at national voyage over 500GT

All passenger ships (national regulations may apply)

• According to the Rhen Convention: All ships over 20m on inland water ways that can move by

their own propulsion

What is AIS?What is AIS?• Regulations took effect December 31st 2004

• Since 2004 AIS Class B units have become more and more common and will probably increase even more in the future.

• Major difference between Class A and Class B units:

The actual data sent out. The reporting interval of the dynamic data.

The principle of sending data => SOTDMA and CSTDMA.

Ouput 2W / 12W

• Dynamic data:

Position => Class A and B

SOG/COG => Class A and B

Heading => Class A and B

ROT => Class A only.

MMSI numberMaritime Mobile Service Identity => Class A and B



• Static data:

MMSI number => Class A and B Call sign => Class A and B Name of ship => Class A and B Overall dimension/

reference for position => Class A and B IMO number => Class A only ETA => Class A only Destination => Class A only Maximum present

static draught => Class A only

• AIS as a system has VERY few limitations => The system will still work even if the load is over 100%!!!

• The weakness of the system is determined by its weakest link. i.e. make sure that the accessories used in the system e.g.

the antennas, antenna cables, connections are 100% secure!!

• If the AIS system is not integrated with the navigational system it will add nothing to the navigation.

• The configuration of the systems.

• Limitation in VHF range (“line of sight”).

• Adequate user training and information about the system and its limitations.

Who sets the standards?Who sets the standards?

• IMO => Decided within MSC (Marine Safety Committee).

• National regulations might apply, e.g.:

EU for fishing vessels

Inland water ways

USA: Plans for smaller vessels

Turkey have there own regulations regarding Class B (12W)

Russia => Must be able to receive position from both the GLONASS and GPS system

Who shall have AIS?Who shall have AIS?


• ITU, with support by IALA.

Who decides about frequenciesWho decides about frequencies??

• IEC, with support by national standard committees.

• IEC TC-80 => Technical committee that handles all marine related electrical and radio standards.

E.g. GMDSS, VHF, AIS, radar etc.

Who decides about test Who decides about test procedures and standards?procedures and standards?


• Foremost IALA and IMO

• IALA develops something called “recommendations”:

E.g. A-123, A-124 and A-126 (guidelines for use of AIS).

Planning of base station networks so they will work w/ time slots etc.

Recommended system redundancy.

In what way different countries shall exchange information about their AIS networks.

• IMO provides installation guidelines and operational guidelines (circulars) to mariners. E.g. how to install the equipment in ships.

Who is decides about operational regulations?Who is decides about operational regulations?

Regulations within 3 years.Regulations within 3 years.

• New regulations within the EU

• All fishing vessels over 15m after 2014 must have a Class A transponder:

From 2012 => All fishing vessels over 24m

From 2013 => 18 – 24 m

From 2014 => All fishing vessels over 15m.

• OK with AIS SART instead of conventional SART to comply with GMDSS regulations.

Pending Regulations.Pending Regulations.

• Updated Class A standard: Increase with two new frequencies

To be able to be received via satellite

• Discussion about PLB´s via AIS.

“What will happen if I activate my AIS PLB?”. Number of MMSI numbers available must be increased.

• New Class B standard for SOTDMA Difference will be what information is sent out. Difference will be how the information is sent out. Difference in output => 2W / 12W

Who controls compliance w/ regulations?Who controls compliance w/ regulations?

• Maritime Authorities.

“Port State Control” in each country

In conjunction w/ e.g. coast guard

MCA (Maritime and Coast Guard Agency) in the UK.

Dover control will call up ships that are visible on radar but not on AIS

E.g. in the US, fines of $1500 if sending out incorrect AIS data

Thank you and we will be more than willing to welcome you on Point Distributions stand to discuss AIS further.
