Today, Inmarsat support both SOLAS and non-SOLAS vessels. Some 1.6 million seafarers depend on the service as a critical communications lifeline that has been proven reliable over the long-term and is not affected by inclement weather. 

Inmarsat services and hardware from Cobham's SAILOR mini-C range have been keeping seafarers safe at sea since 1999 when GMDSS was formed by the International Maritime Organisation (IMO). The solutions deliver critical connectivity through the receipt and transmission of vital ship-to-shore and shore-to-ship distress alerts.

The mini-C system features true triple functionality as it safely handles all GMDSS, SSAS and LRIT operation on board.


Distress Alerting

Distress alerts are issued when a ship or crew is in imminent danger. When there is no time to input information manually into the terminal, the crew can simply press and hold down the Dedicated Distress Button for approximately five seconds to transmit the alert.
