Maritime Operations

Stay connected
and prepared at sea.

Keep crews connected beyond coastal mobile coverage with satellite voice, data and dedicated emergency equipment designed for vessels operating offshore.

Voice, data & safety at sea

Reliable communication matters beyond the shoreline.

Once a vessel moves beyond dependable coastal mobile coverage, everyday communication becomes much harder. Commercial crews, offshore teams and recreational mariners may still need to make calls, access weather information and stay in contact with people ashore.

Satellite technology provides several different layers of connectivity and safety. Handheld phones provide direct voice communication, portable hotspots support essential data services, while dedicated marine beacons provide another way to raise the alarm in an emergency.

01

Maintain voice contact offshore

Satellite phones provide direct communication when conventional mobile networks no longer reach the vessel.

02

Access essential data

Satellite hotspots can support messaging, email, weather information and selected online applications at sea.

03

Prepare for serious emergencies

Dedicated marine distress beacons provide another route for alerting Search & Rescue when assistance is needed.

Expert advice

Building the right communications setup for your vessel?

A small workboat, offshore crew and long-distance vessel can have very different communication and safety requirements. Tell us where you operate, how many people need to connect and what services you need onboard, and our team can help you choose the right equipment.

Maritime communication FAQs

Staying connected and prepared at sea.

Maritime communication often requires several layers of equipment. Voice, data and emergency beacons serve different purposes, so the best setup will depend on the vessel, route and type of operation.

Do satellite phones work at sea?

Yes. Satellite phones are widely used for maritime communications where conventional mobile coverage is unavailable. The handset needs an appropriate view of the sky and an active satellite airtime plan.

Why use Iridium for maritime communication?

Iridium provides global satellite coverage, including open oceans and polar regions. This makes compatible Iridium phones and data devices particularly useful for vessels travelling beyond coastal communications infrastructure.

What can I do with an Iridium GO! exec at sea?

GO! exec can provide compatible smartphones, tablets and laptops with satellite voice and light data access. Typical uses include messaging, email, weather information and supported low-bandwidth applications.

Is Iridium GO! exec a replacement for marine broadband?

Not usually. GO! exec is designed for essential lower-bandwidth communications rather than high-speed broadband. Vessels needing heavier internet use, streaming or large file transfers may require a higher-bandwidth maritime satellite solution.

What is an EPIRB?

An Emergency Position Indicating Radio Beacon is a dedicated vessel distress beacon. When activated in an emergency, it transmits a distress alert through the international Search & Rescue satellite system to help authorities identify and locate the vessel.

Is an EPIRB the same as a satellite phone?

No. A satellite phone is a communications device used for voice and messaging, while an EPIRB is dedicated emergency equipment intended to transmit a distress alert. They perform different roles and can form part of the same overall maritime safety setup.

Do maritime satellite devices require airtime?

Satellite phones and data devices require an active service or airtime plan. EPIRBs work differently and do not require a commercial satellite airtime subscription, although the beacon must be correctly registered and maintained.
