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…

Study: Space-Based ADS-B Will Help Curb Aviation Emissions

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. Beyond the reach of land-based radar, aircraft flying on oceanic routes must report their position by satellite link or HF voice radio when they arrive at predetermined waypoints. With less frequent information on the whereabouts of such aircraft, air navigation service providers (Ansps)…

More Efficient ATM Could Clear the Skies of 14.3 Metric Tons of CO2, Study

A new study finds that more efficient air traffic management—through the implementation of space-based automatic dependent surveillance broadcast (ADS-B)—could reduce aviation’s CO2 emissions by approximately 14.3 million metric tons between 2020 and 2030. The report, Environmental Benefits of Space-based ADS-B, was authored by Dr. Karen Marais, Associate Professor School of Aeronautics and Astronautics Purdue University. This reduction of CO2 emissions would be equivalent to removing more than 300,000 cars from U.S. roads each of those years, and would require no changes to aircraft design or jet fuel.

This Technology Will Make Missing Planes a Thing of the Past

It’s called ADS-B, and it’s a big deal for aviation. Of the many questions raised by the vanishing of Malaysia Airlines Flight 370 in 2014, the most vexing was also the most fundamental: How could aviation authorities lose track of an entire Boeing 777 BA 0.87% and the 239 people on board? Many were surprised to learn that across vast swaths of the planet—particularly over oceans—air traffic controllers have only a vague idea of the location of many of the world’s airliners at any given moment. “Air traffic controllers aren’t…
