Inmarsat has steadily set the bar for flight deck communications, with over two decades of commitment to aviation safety services. More than 95% of the world's transoceanic aircraft use our safety and operational services for communication and surveillance today – around 11,500 aircraft in total.
In 2015, Inmarsat reported about 100,000 aircraft positions a day and 35 million throughout the whole year, through our extensive satellite network. Most of the world's leading airlines have used our Classic Aero services for over 25 years – as well as small, medium and large business jet owners, general aviation and government agencies.

Classic Aero delivers operational and safety-critical services such as Automatic Dependent Surveillance – Contract (ADS-C) and Controller-Pilot Data Link Communications (CPDLC) communications between the cockpit and air traffic control. When Inmarsat began offering these robust communications and surveillance services in 1990, we made it possible to reduce the separation requirements between aircraft in the sky, expanding oceanic airspace capacity by over 300% and savings airlines millions over the following decades.
Classic Aero's multi-channel voice, data, and fax capabilities are available in three types of antennas: high gain (Aero H and H+) and intermediate gain (Aero I). They offer International Civil Aviation Organization (ICAO)-approved communications for safety and regularity of flights along national and international civil air routes. Our equipment is standard on the world's oceanic air routes and meets ICAO's global flight tracking requirements using ADS-C.
