The Global Maritime Distress and Safety System, generally known as GMDSS, is a globally renowned search and recovery radio system for ships that have been adopted by the world’s maritime states, including Singapore. GMDSS is an automated ship to the land system that uses a mixture of selective digital and satellite technology to replace the earlier, largely Morse code based ship to ship crisis communications. Any ship should carry a portable GMDSS radio to protect the safety of both crew and passengers.
GMDSS Portable Radios For Safety At Sea
Premium maritime electronics brands like Entel and Jotron are only distributed by Allied eParts. The MED-certified Entel HT649 GMDSS VHF Portable Radio is among the GMDSS portable radio and devices available in the market. The commercial-grade radio is extremely safe and provides outstanding audio quality irrespective of the surroundings. The GMDSS radios provide intuitive user interfaces, excellent sound quality, and portable and small designs for increased comfort and reliability in high-seas circumstances.
Even when using thick gloves or in slick conditions, an ergonomic portable radio can efficiently access international GMDSS channels. The portable GMDSS radios come with all of the necessary supplies, including an emergency lithium battery, rechargeable battery, and adapter.
What does GMDSS consist of?
DSC (digital selective calling) is a standard for transmitting pre-defined digital messages between ships, ships and shores, and shores and ships. VHF, MF, and HF maritime radio communication are used.
EPIRB (emergency position indicating radio beacon) — automatic identification and locate device used in Search and Rescue operations.
NAVTEX is an international automated service that provides ships with navigator and meteorological warnings, estimates, and other critical maritime safety information.
Search and Rescue locating equipment – by signalling search and rescue radar transponders, search and rescue units are automatically directed to the location of the crisis.
INMARSAT – a global mobile satellite communication system that transmits data and messages in both directions.
DSC refers to the automated monitoring of distress channels on VHF, MF/HF radios. The satellite communication system relies on a satellite network that extends up to the A3 sea area. Position Indicating an Emergency During an emergency, radio beacons (EPIRB) and Search and Research transponders send out distress and location signals.
EPIRBs are compact devices that transmit signals on the 406MHz frequency using the global COSPAS-SARSAT satellite System, whilst SARTs are portable radar transponders that operate on the radar “X” and “S” radio frequencies.
