Equipment required for the Long Range Identification and Tracking (LRIT) for vessels flying the flag of the Netherlands

The NSI provides information on the implications of Long Range Identification and Tracking (LRIT) for vessels flying the flag of the Netherlands. 

Some extracts are copied here after but full information are displayed on their website:


Type approved equipment

 Type-approved equipment shall be used for LRIT. Existing radiocommunication equipment, such as various types of Inmarsat-C terminals, can often be adapted to LRIT in a relatively simple manner. The testing of the equipment shall be performed by so-called 'authorized testing ASP’s' (Application Service Providers).


So far the following testing ASP’s are qualified:

  •          Alewijnse Marine Systems B.V. in Krimpen aan den IJssel

  •          Alphatron Marine B.V. in Rotterdam

  •          RH Marine Netherlands B.V. in Rotterdam

  •          Pole Star Space Applications Limited in London, United Kingdom, in combination with above mentioned companies

  •          SAM Electronics B.V. in Rotterdam

  •          Collecte Localisation Satellites (CLS) in Ramonville Saint-Agne (Frankrijk), also recognised ASP for the EU Data Centre.


 Provide appropriate ship data


In order to have LRIT function properly, it is necessary that the ship data registered at the LRIT Data Centre are correct. It is the ship owner’s responsibility to provide for appropriate and up to date data.

The data must be provided for by sending a digital copy of the LRIT Conformance Test Report. This report must be sent in case of a new ship, flag in of a ship or any mutation in the ship data or LRIT equipment.

When a ship is flagged out or taken out of service, an email must be sent including the country of destination.

The LRIT Conformance Test Report must include the following data:

  •          Name of ship

  •          Call sign

  •          IMO

  •          MMSI

  •          Type of LRIT communication system

  •          Serial number

  •          Terminal ID (i.e. Inmarsat number)


A digital copy of the LRIT Conformance Test Report or the message concerning the flagging out of a ship must be sent to:

Radiocommunications Agency




Procedures to make LRIT-equipment operational (again)


The causes of not -or not correctly- reporting LRIT-equipment may be found in the equipment (software or sensor such as GPS), in obstruction of the signal by the environment, in human actions, etc.

The EMSA has established procedures to render the LRIT-equipment operational (again). You find these procedures in 'Procedures to improve ship integration and ship reporting'.


Attention: After completion of the conformance test by the authorized testing ASP the LRIT equipment shall be kept in operation and shall not be turned off or logged out, in order to guarantee a successful integration in the LRIT system.

Switching off the LRIT equipment is only allowed in exceptional circumstances (see  the Leaflet LRIT below) in the case of which the Dutch Coast Guard shall be informed.


The Netherlands Shipping Inspectorate advises ship owners not to instal LRIT equipment on:

  •         vessels smaller than 300 GT (except passenger ships)

  •         vessels equiped with an Automatic Identification System (AIS) that exclusively sail in Sea Area A1
