Background What is AIS?

AIS - Automatic Identification System is one of the most important and useful introduction of navigation technology since the radar

AIS is a shipboard broadcast transponder system in which ships continually transmit their ID, position, course, speed and other data to all other nearby ships and shore side authorities on a VHF radio channel. By "clicking" on a ship symbol, users can learn the ship name, course and speed, classification, call sign, registration number, and other information;

AIS is designed to operate in one of the following modes: In a ship-to-ship mode; As a means for coastal states to obtain information about a ship and its cargo; As a traffic management tool when integrated with a Vessel Traffic System (VTS).

Data exchange is automatic and transparent to the user Enables a ship operator to obtain vital information on the surrounding area

through various environmental conditions and other obstacles.

Background History

Concept is derived from the work of the Swedish inventor Håkan Lans;

Based on spontaneous, master-less communication, allowing multiple transmitters to send data over a single narrowband radio channel;

Transmission done by synchronizing data transmissions to a very precise timing slot.

The idea behind the AIS is to enable a ship operator to “see” the surrounding area, more clearly and thus improve the vessel’s safety by reducing the amount of collisions in the water;

Data can be logged to a Voyage Data Recorder (VDR) for playback and future analysis

The need for AIS and its requirements and definitions were established by the United Nations (UN) with the utilization of the IMO (International Maritime Organization), ITU (international Telecommunication Union) and the IEC (International Electrotechnical Commission).

Background Common Acronyms

AIS – Automatic Identification System VTS – Vessel Traffic System UN – United Nations IMO – International Maritime Organization ITU – international Telecommunication Union IEC – International Electro-technical Commission VHF – Very High Frequency VDR – Voyage Data Recorder WAN – Wide Area Network TDMA – Time Division Multiple Access STDMA – Self-Organizing Time Division Multiple Access GNSS – Global Navigation Satellite System

Applications Collision Avoidance

Used only to determine risk of collision rather than as an automated collision avoidance system in accordance with the International Regulation for Preventing Collisions at Sea (COLREGS)

- 6 -

Problem – Collision Solution – Collision Warning

- 7 -

Applications

Vessel Traffic Services (VTS) Provides additional information on the type of vessels and their movement among other

useful vessel specific data for enhances traffic awareness and management

Problem – Any Vessel Nearby? Solution – Situational Awareness

- 8 -

Applications

Aids to Navigation Ability to broadcast positions and names of objects, such as lighthouse, buoys and marker

positions

Problem – Platform Location Solution – Mapped Platform

- 9 -

Applications

Search and Rescue Status information of vessels in the vicinity of a vessel or person in distress

Problem – Ship in Distress Solution – Routing Rescue Crew

- 10 -

Applications

Accident investigation Providing accurate time, identity, position, compass heading, speed, rate of turn, etc. of the

vessels involved in an accident for analysis.

Problem – What Happened? Solution – Control Centre Analysis

- 11 -

Applications Binary Messaging

Other than navigational information such as water levels, canal lock orders, etc. For example, the Panama Canal uses AIS type 8 messages to provide information about rain

along the canal and wind in the locks

Solution – Tide Awareness MessageProblem – Low Tide Level

- 12 -- 12 -

Market Requirements

Vessels operating along the Rhine (Europe) to install an AIS device by 2012 (along with other rivers along European countries such as Belgium, Turkey, Russia)

EU fisheries requires all commercial fishing vessels in the EU to fit an AIS device by 2014

Asian countries developing mandates covering sea and river travel. For example, Japan is considering covering about 110,000 vessels.

Projections predict that over 1,000,000 vessels will require AIS by the year 2014; of which only about 15% are already equipped with AIS

As AIS applications and benefits are being recognized world wide, AIS placement potential increases significantly for both shipborne and in land installations.

- 13 -- 13 -

Mandates and Trends IMO established mandatory carriage requirements for approved AIS

equipment under the Safety of Life at Sea (SOLAS) Convention. The AIS carriage requirements apply to (but not only): All ships of >300 gross tonnage engaged on international voyages Cargo ships >500 gross tonnage and upwards not engaged on

international voyages All passenger ships irrespective of size

Check our website, www.comnav.com, US coast guard website, www.navcen.uscg.gov, or other government agencies and regulatory bodies for further details and information on other mandates.

Standards and Regulations

3 main international standards organizations regulate AIS Standards: IMO – International Maritime Organization IEC – International Electromechanical Commission ITU – International Telecommunication Union

ComNav Product Range

ComNav Marine offers both Class A and Class B AIS

systems:

AIS Typical Setup

- 17 -

Key Features of AIS See and be seen - Class B transponder continuously receives information from all

Class A and Class B equipped vessels in its vicinity, and displays this information on a standard chart plotter or PC. At the same time Class B will transmit your position to all AIS equipped vessels automatically.

Safety at night and in poor weather conditions

Class B AIS is a vital navigation tool in poor visibility conditions. The information received from other AIS ‘targets’ provides the user with vital navigation information and position transmission to alert other vessels to the user’s location.

Combined with radar, AIS provides the best possible awareness of the situation in all conditions

- 17 -

Key Features of AIS

Safety in high traffic / commercial shipping areas

Position transmission to authorities / nearby vessels in case of emergency

Best possible updates of a dynamic environment (moving vessels)

Graphically view own vessel position in relation to other vessels when connected to suitable display

Ability to ‘see around the corner’

Track vessels of interest such as friends / colleagues

Types of AIS

Class A Ship borne mobile equipment intended for vessels meeting the requirements of IMO AIS

carriage requirement. Inland Waterways AIS

Based on the specification of Class A shipborne AIS equipment in accordance with current revision of ITU-R Recommendation M.1371 and IEC standard IEC 61993-2 : 2001

Class B Ship borne mobile equipment provides facilities not necessarily in full accord with IMO AIS

carriage requirements. (2W standard,12W optional)

- 21 -

AIS Class A and Class B differences Class B varies from Class A with features listed below:

Has a reporting rate less than a Class A (e.g. every 30 seconds when under 14 knots, as opposed to every 10 seconds for Class A)

Does not transmit the vessel's IMO number

Does not transmit ETA or destination

Does not transmit navigational status

Is only required to receive, not transmit, text safety messages

Is only required to receive, not transmit, binary messages

Does not transmit rate of turn information

Does not transmit maximum present static draught

AIS Detailed Description AIS utilizes a unique self-organizing time-division multiple access

(STDMA) data communications scheme: Uses the precise timing data in the GPS signals

Range typically expected at sea is nominally 20 nautical miles

System coverage range depends on the height of the antenna

AIS exchanges messages with all ships within VHF radio range

Synchronize multiple data transmissions from many users on a single narrowband channel

- 24 -

Detailed Description

The area in which AIS messages can be received is called the ship’s “cell”

STDMA protocol - each minute of time is divided into 2,250 timeslots

2 channels essentially allow 4500 time slots Two dedicated frequencies for AIS. They are 161.975 MHz

(marine band channel 87B) and 162.025 MHz (channel 88B)

- 25 -- 25 -

AIS Messages Information provided by the AIS falls into several categories:

Static Data Dynamic Data Voyage Related Data Safety Related Messages

The update rates for dynamic information depend on the ship’s status and speed, according to the following schedule: At anchor - 3 minutes 0-14 knots - 10 seconds 0-14 knots and changing course - 3 1/3 seconds 14-23 knots - 6 seconds 14-23 knots and changing course - 2 seconds 23+ knots - 2 seconds 23+ knots and changing course - 2 seconds
