Purdue University: Satellite-based Aircraft Tracking Offers Big Emissions Cuts


Satellite-enabled aircraft tracking, known as Automatic Dependent Surveillance-Broadcast (ADS-B), can help to curb aviation carbon emissions in the near term, a new study by Purdue University confirms. Government bodies in Europe, the United States, Australia and other regions throughout the world currently require that most aircraft equip with ADS-B technology to reduce aircraft separation and help pilots fly more efficient routes. However, while aviation authorities have put terrestrial infrastructure in place to enable the technology, its impact is limited over remote and oceanic regions.

“Terrestrial ADS-B is impractical over much of the ocean, because it requires ground-stations. In shallow, near-shore waters it is possible to have such stations, but the logistics in the open ocean make terrestrial ADS-B are far too challenging,” report author Karen Marais told Via Satellite. “Currently satellite-based technologies like ADS-B are the most practical solution to providing navigation coverage over the open ocean.”
