Study: Space-Based ADS-B Will Help Curb Aviation Emissions
Closer spacing with more efficient routing and operations will help the aviation industry meet environmental goals, Aireon-funded study finds.

Satellite-enabled signaling by aircraft transiting oceanic routes offers a near-term solution to curbing aviation emissions, asserts a Purdue University study. Aireon, the joint venture developing a space-based surveillance system based on automatic dependent surveillance-broadcast (ADS-B) position reporting, funded the study by Purdue’s school of aeronautics and astronautics.
