Satellites will soon be used to keep an independent eye on airborne planes, under a deal agreed between ESA and Spire Global, a company that provides space-based data, analytics and space services. Spire will design an advanced civilian aviation surveillance system that uses a constellation of satellites to monitor flights globally in real time, as well as building an in-orbit technology demonstrator for the system.
The system, called “Eurialo”, will determine the exact position of a plane by geolocating its radio frequency signals. This will provide an independent assessment of the plane’s location to complement today’s surveillance systems, which often rely on self-reported positions of aircraft derived from the Global Navigation Satellite System. The project will not only provide reliable and resilient surveillance to complete the European communication, navigation and surveillance infrastructure, but also align with the European air traffic management master plan, which describes the need for resilient, space-based infrastructure to support safe, sustainable and efficient air travel.
