Purdue University’s School of Aeronautics and Astronautics researched the potential impact of space-based ADS-B on global aviation carbon emissions in remote and oceanic airspace.
Extensive search and rescue efforts following recent high-profile airline disasters have left the general public largely surprised that the exact location of aircraft is often unknown in oceanic and remote airspace. In response, ICAO has recommended that aircraft provide position reports every 15 minutes by November 2018 and several tracking solutions are being considered by airlines, ANSPs and regulators. Unfortunately, there exists a great deal of confusion around what should be considered “surveillance” and what should be considered “tracking”.
