The ability to exchange safety-related messages with other ship and shore stations by a ship in distress is assured for vessels complying with SOLAS (Safety of Life at Sea) rules. The rule provides for transmission and reception of distress alerts as well as on-scene communications, amongst other, using different radiocommunication systems.
Equipment dedicated for safety-related (GMDSS) and operational communications onboard include.
- VHF Fixed Radiotelephony
- VHF Portable Radios
- MF/HF Radiotelephony
- 406 MHZ AIS EPIRB
- 9 GHz Radar Transponder and AIS SART
- Inmarsat C system
- Navtex Receiver
Broadband communications at sea on the Ku- and Ka-band have changed the way vessel communicate. The high-performance satellite link to head office and social network, real-time weather information, and chart correction updates have enhanced vessel productivity and crew well-being at sea.
Satellite connectivity on the L-band also provide simultaneous voice and data capability albeit at lower bandwidth, but with 100% global coverage on the Iridium Certus networks.
Lars Thrane's high-performance Iridium Satellite phones are manufactured for High-Sea going vessels, Workboats, Fishing and security-patrol vessel.
The LT-3100S is SOLAS GMDSS approved as an alternative to the Inmarsat C and offers following features:
- Distress Alert and Call
- Safety Calling and Messaging
- Maritime Safety Information (MSI)
- Long Range Identification and Tracking (LRIT)
- Voice and SMS service
