ESA sees satellite-based air traffic monitoring on near horizon
The European Space Agency has awarded a contract to a US company to create a technology demonstrator for a proposed aircraft monitoring system using low Earth orbit satellites., headquartered in San Francisco, won the €16 million agreement for the EURIALO project, which aims to prove that a satellite-based system can monitor aircraft in flight for air traffic management purposes, without relying on any existing systems.
The company already operates a constellation of nanosatellites that are used to observe the Earth in real time at radio frequencies, providing data to inform global weather intelligence, and ship and plane movements, according to Spire.intends to demonstrate the viability of using satellites to track aircraft by determining in real time the aircraft position based on timing the arrival of radio signals detected by multiple satellites, a technique known as multilateration.
Current monitoring systems largely rely on self-reported positions of aircraft, which are typically obtained from satellite navigation systems. The objective of EURIALO is to provide a complementary tracking system that can feed location data to existing air navigation service providers for integration into their services.
Ultimately, this could help track planes in real time from takeoff to landing anywhere in the world and could more speedily locate aircraft in the event of an emergency. It isn't clear whether such a system would have helped in the infamous case of
