There are a number of reliable ship tracking devices available on the market today based
upon Inmarsat and other satellite systems.
The IMB endorses ShipLoc, an inexpensive satellite tracking system, which allows shipping
companies, with Internet access, to monitor the exact location of their vessels. In addition to
its anti-hijacking role, ShipLoc facilitates independent and precise location of ships at
regular intervals. ShipLoc is fully compliant with the IMO Regulation SOLAS XI-2/6 adopted
during the diplomatic conference in December 2002, concerning a Ship Security Alert
System. The ship security alert system regulation that came into force in July 2004 requires
ships of over 500 GT to be equipped with an alarm system in order to reinforce ship security.
The system allows the crew, in case of danger, to activate an alarm button that automatically
sends a message to the ship owner and to competent authorities. The message is sent without
being able to be detected by someone on-board or by other ships in the vicinity. ShipLoc is
contained in a small, discrete waterproof unit, which includes: an Argos transmitter, a GPS
receiver, a battery pack in case of main power failure, and a flat antenna. ShipLoc is one of
the most reliable systems available today. For more information, please visit
