AIS-CTRX Class B AIS Transponder ManualGENERAL NOTICEThe Automatic Identification System (AIS) unit mostly utilise a Global Navigation SatelliteSystem (GNSS) system such as e.g. GPS or GLONASS to determine position.The accuracy of these systems is variable and can be affected by factors such as thepositioning of the antenna, the number of satellites available to determine a position and forhow long satellite information has been received.It is desirable as often as possible to verify both your vessel’s AIS derived position data andother vessels AIS derived position data with visual or radar based observations.The compass safe distance of this unit is 0.5m or greater for 0.3 deviation.P1.0E12LD2103

AIS-CTRX Class B AIS Transponder ManualLICENSINGIMPORTANT: In most countries the operation of an AIS unit is included under the vessels marine VHFradio licence provisions. The vessel on to which the AIS unit is to be installed must therefore possessa valid VHF radiotelephone licence which lists the AIS system and the vessel Call Sign and MMSInumber.Please contact the relevant authority in your country for more information.In accordance with our policy of continuous development and product improvement the AIS-CTRXhardware and/or software may be upgraded from time to time and future versions of the AIS-CTRXmay therefore not correspond exactly with this manual.When necessary upgrades to the product are made, these will be accompanied by updates oraddenda to this manual.Please take time to read this manual carefully to understand its contents fully so that you can installand operate your AIS system correctly.Information contained in this manual is liable to change without notice.True Heading AB disclaims any liability for consequences arising from omissions or inaccuracies inthis manual and any other documentation provided with this product. 2006 True Heading ABP1.0E13LD2103

AIS-CTRX Class B AIS Transponder ManualINFORMATION ABOUT AISGeneralAIS (Automatic Identification System) is the name of a system that makes it possible for ships toidentify other ships and to monitor ship movements. The reason for implementing the AIS system is forthe mariner to obtain more information about ships in the vicinity than what radar is able to provide.AIS gives e.g. information about a ships identity (name, call sign, IMO number and MMSI), size thiseven for ships behind Island or bends that radar cannot detect.AIS is used to enhance safety for life at sea, improve safety and efficiency in navigation and protectthe marine environment.AIS-information transmitted from a ship contains of three (3) different main types:- Static data that was programmed into the AIS equipment at installation and it only needs to bechanged if the ship changes its name, flag or undergoes a major refit where size or ship type ischanged;- Dynamic data contains information that automatically is updated from ship sensors like the headingfrom the Gyro, Position and speed from GNSS equipment. Also navigational status belongs to thegroup of dynamic data but is updated manually by the crew; and- Voyage related data that manually is updated by the crew along the voyage.From the start AIS some times also was referred to as UAIS or as the 4S transponder system thatmeant Ship to Ship and Ship to Shore.IMO adopted 1998 a performance standard for AIS within the SOLAS requirement that described ingeneral how AIS should work. Below follows a brief description of the main requirements for AIS fromthe performance standard: Automatically provide information to AIS land stations, other ships and airborne units e.g. SARhelicopters about the ships identity, Type of ship, Position, Course, Speed, Navigational status(e.g. under way using engine, at anchor) and other safety related information of importance.Be able to receive the same type of information from other ships.Be able to monitor and track other ships.Exchange information with land based AIS systems.AIS is an automatic system that continuously and simultaneously transmits on two channels in themaritime VHF frequency band.AIS can handle several reports in a rapid consecutive flow. To accomplish these AIS uses a techniquecalled Self Organized Time Division Multiple Access (SOTDMA) that guarantees high transmissionsafety and operational robustness.AIS also allows for other types of information from e.g. sensors like Gyro, GPS and echo sounders etc.to be transmitted automatically.Important areas where AIS is used are: P1.0EInformation exchange between ships within VHF range (normally 20-30 NM) to enhancesafety at sea and to improve situation awareness.14LD2103

AIS-CTRX Class B AIS Transponder Manual Information exchange between ships and AIS land stations as e.g. a VTS that controls andmonitors maritime traffic in an area. Automatic reporting in areas with mandatory reporting of different kinds. Exchange of safety related information between ships and between ships and land stations. Services like e.g. meteorological information in real-time from areas of importance, identityand position of floating and fixed aids to navigation to improve identification and navigation.How AIS WorksThe marine Automatic Identification System (AIS) is a location and vessel information reportingsystem. It allows vessels equipped with AIS to automatically and dynamically share and regularlyupdate their position, speed, course and other information such as vessel identity with similarlyequipped craft. Position is derived from a Global Navigation Satellite System (GNSS) network andcommunication between vessels is by Ver
