Safety communications

Inmarsat was the first operator to comply with the requirements of the International Civil Aviation Organization (ICAO) for global safety communications. Today, Iridium has been approved for Safety Services under the FANS over Iridium program.

IDG will work with our customers to suggest cost effective hardware and services to meet your requirements.


Inmarsat aviation network

Satellite-aided ATC

When an aircraft is out of range of VHF/UHF radio, such as in oceanic airspace, Inmarsat enables satellite-aided air traffic control (ATC). The ability to have reliable communications with ground-based controllers at all times, on all major oceanic routes, is an important safety feature.

Automatic dependent surveillance (ADS)

Inmarsat facilitates the automatic reporting of an aircraft’s real-time position, including altitude, speed and heading, via satellite to air traffic control centres, helping controllers know where an aircraft is at all times.

Controller / pilot datalink communications (CPDLC)

We also enable Aircraft Communications Addressing and Reporting System (Acars) routing instructions, clearances and other messages to be sent directly to the cockpit as electronic data messages. The benefits are increased flight safety and efficiency through more effective communications.

Voice services

Our satellite services also support air traffic control and critical airline voice communications when the aircraft is out of VHF radio range. The aircraft systems are set up so that the cockpit communications have priority over any of the passenger communications, so maximising safety and reliability.
