An experimental receiver on ESA’s Proba-V satellite pinpointing the location of aircraft in flight over the Atlantic approach to western Europe and the UK through their ADS-B signals. Automatic Dependent Broadcast – Surveillance (ADS-B) signals are regularly broadcast from equipped aircraft, giving flight information such as speed, position and altitude. On 23 May this DLR-contributed experiment was switched on for the first time, recording over 12000 ADS-B messages within two hours at an altitude of 820 km. Image copyright DLR/SES TechCom.
