An incredible map from Proba-V satellite orbiting the Earth shows signals from thousands of aircraft around the globe. The findings can pave the way for future missions that could track global air traffic from space.
The satellite, launched by the European Space Agency (ESA) in 2013, was carrying out various technological experiments, and the main one was tracking changes in plant growth across the Earth every two days.
But the probe was also experimenting with detection of Automatic Dependent Surveillance Broadcast (ADS-B) aircraft signals from space, the test that was added by DLR German Aerospace Center and the SES satellite company, based in Betzdorf, Luxembourg. Those signals give flight information such as speed, position and altitude. Thus, Proba-V, which is smaller than a cubic meter, managed to pick up about 25 million positions from more than 15,000 jets.
