For nearly 30 years, Avidyne has been inventing new ways to simplify flying for pilots who fly small planes, business jets, helicopters and advanced air mobility aircraft. With design and manufacturing done in the USA we are headquartered in Melbourne, FL and have additional facilities in Westerville, OH, and Concord, MA.

Aireon has deployed a space-based air traffic surveillance system for Automatic Dependent Surveillance-Broadcast (ADS-B) equipped aircraft throughout the entire globe. Aireon harnesses next-generation aviation surveillance technologies that are currently ground-based and, for the first time ever, extend their reach globally to significantly improve efficiency, enhance safety, reduce emissions and provide cost savings benefits to all stakeholders. Real-time ADS-B surveillance covers oceanic, polar and remote regions, as well as augment existing ground-based systems that are limited to terrestrial airspace. In partnership with leading ANSPs from around the world, like NAV CANADA, Iridium Communications, ENAV, NATS, the Irish Aviation Authority (IAA), and Naviair, Aireon will have an operational, global, space-based air traffic surveillance system in early 2019.
