Satellite radio communications at sea

Radio at sea is essential for mariners to communicate onboard and with the shoreside. It's essential to have GMDSS compliant safety equipment on board for the safety of your crew.

Reliable, easy to use maritime VHF, MF/HF and UHF radio is available from AST Networks enables effective, quick communication anywhere in world – from the remote sea to far reaching polar oceans.

In today’s digitally-focused world, radio communication is not the only connectivity demand a vessel requires. Mariners depend on our fully managed connectivity services and solutions in order to sail safely, effectively and serve the needs of the crew.

Safety radio

Safety radio is essential life-saving equipment that, under the safety of life at sea convention, vessels are required to have onboard.

The global maritime distress safety system (GMDSS) minimum requirement is to have at least two handheld VHF handsets and at least one VHF digital selective calling (DSC) hardware onboard in order to raise a signal. The further a vessel travels into far-reaching sea areas the more safety at sea equipment is needed.
