Maritime mobile Access and Retrieval System (MARS)

​The main objective of the ITU MARS webpage is to provide the maritime community and administrations with the means to access and retrieve operational information of Ship Stations, Coast Stations, SAR Aircraft, AIS Aids to Navigations (AtoNs), Accounting Authorities and Administrations that have been notified to the Radiocommunication Bureau by Administrations of the ITU Member States. The operational information is updated on a daily basis.

Ship Stations

 
 
Retrieval of information Notification
 
Retrieval of information: Provides the identification (i.e. MMSI, call sign, ship name), in order to contact individual ships at sea and/or assist maritime Search And Rescue (SAR) authorities in organizing their operations in the event that a ship is in a distress situation. Details of the radio equipment carried on board, IMO number, EPIRB id codes, notifying administration (flag state), contact information of the Accounting Authorities, etc. are also available.
 
Notification: Administrations of the ITU Member States are invited to submit data (cf. provision No. 20.16 of the Radio Regulations), using the relevant notification forms.

Coast stations

 
 
Retrieval of information Notification
 
Retrieval of information: Provides information (MMSI, call sign, operational frequencies, hours of service, etc.) that are useful for ships at sea for contacting coast stations and for authorities involved in Search and Rescue (SAR) operations including the Global Maritime Distress and Safety System (GMDSS). Details of the services provided by these stations, such as watch-keeping using Digital Selective Calling (DSC) techniques and radiotelephony, medical advice, navigational and meteorological warnings, Maritime Safety information (MSI), Automatic Identification System (AIS), meteorological bulletins, etc., are also available.
 
Notification: Administrations of the ITU Member States are invited to submit data (cf. provision No. 20.16 of the Radio Regulations), using the relevant notification forms.

SAR aircraft

 
 
Retrieval of information Notification
 
Retrieval of information: Provides details of the identification (i.e. MMSI) of aircraft involved in Search and Rescue (SAR) operations and other safety related communications with stations in the maritime mobile service. Details of the type of aircraft (fixed wing, helicopter), maritime radio equipment on board and contact information of the License holder are also available.
 
Notification: Administrations of the ITU Member States are invited to submit data using the relevant notification forms.

AIS Aids to navigation (AtoN)

 
 
Retrieval of information  Notification
 
Retrieval of information: Provides details of the identification (i.e. MMSI) of the AIS aids to navigation (AtoN). Information on the type of AtoN, its geographical coordinates, dimensions (height, width and length) and type of electronic position fixing device are also available.
 
Notification: Administrations of the ITU Member States are invited to submit data using the relevant notification forms.

Accounting authorities (AAIC)

 
 
 
An accounting authority acts as a billing intermediary between the maritime mobile station and service providers. The role of an accounting authority may be undertaken by an Administration; a Recognized Operating Agency (ROA); or any other entity or entities designated for this purpose by the Administration.
 
An accounting authority must be registered with an Administration and subject to a periodic review (for example, annually) by the Administration or its national Regulatory Body on the financial position and effectiveness of each accounting authority.

registration of AAIC

  The registering Administration should:

An Administration that accepts an accounting authority outside its own country for maritime mobile stations under its flag, is responsible for notifying the ITU of this fact and of the Accounting Authority Identification Code (AAIC) allocated to that accounting authority, through an official email to brmail@itu.int.
