First results from the new Aireon space-based Automatic Dependent Surveillance – Broadcast (ADS-B) services using 66 orbiting transponders reveal significant gains in fuel efficiency and environmental impact for airspace users.

Air navigation service providers (ANSPs) Nav Canada and NATS have been using space-based ADS-B data since the end of March this year to track aircraft flying between North America and Europe, with impressive results.
