Eurialo: The Future of Air Traffic Management with Space-Based Aircraft Tracking

The European Space Agency and Spire Global join forces to introduce 'Eurialo', a cutting-edge civilian aviation surveillance system, ensuring real-time, precise tracking of flights worldwide

Picture this: a trailblazing array of satellites floating in Earth’s orbit, offering real-time, pinpoint accuracy in tracking flights around the globe. This soon-to-be reality is the result of an innovative collaboration between the European Space Agency (ESA) and space-data firm Spire Global, marking a significant evolution in aviation surveillance systems.

The duo has christened this project ‘Eurialo’, a groundbreaking civilian aviation surveillance system. Unlike traditional methods that rely on radar signals and the self-reported positions of aircraft via the Global Navigation Satellite System, Eurialo takes a more space-age approach. The key to its operation is its ability to capture and geolocate the radio frequency signals of a plane, consequently determining its precise position in real-time.

Let’s rewind for a moment and discuss the existing radar-based tracking system for planes. In this method, radars send out electromagnetic waves that traverse the airspace, bouncing off airborne objects they encounter. The position of these objects, mainly planes, is then determined by measuring the distance between the source of the wave and the point of impact.

However, this system is far from flawless. Our diverse and often towering landscape poses challenges. Mountains, skyscrapers, and vast water bodies can act as obstructions, often preventing the receiver from successfully capturing the radar signal. Such hindrances can lead to inaccuracies in determining the exact location of an aircraft.

The ESA’s current tracking methodology also includes a dependence on self-reported locations from aircraft, delivered through the Global Navigation Satellite System. While this offers another data point for aircraft location, it doesn’t completely alleviate the problems posed by radar tracking.

This is where the future-forward Eurialo system leaps into the picture. The overarching goal is not just to provide an alternative but to offer a more robust, reliable, and complementary solution to the current communication, navigation, and surveillance infrastructure. In essence, Eurialo aims to improve air traffic management, creating a seamless interface between air and ground. The promise it holds is remarkable – the ability to monitor an aircraft’s journey, from take-off to landing, in real-time, anywhere in the world.

As part of the agreement, Spire Global is taking the lead in the preliminary design of the satellite constellation that will form the backbone of Eurialo. The firm will also deploy and conduct a test mission to gauge the system’s performance. Peter Platzer, Spire’s CEO, articulated the significance of the endeavor, stating, “Space-based aircraft tracking and geolocation is the future of air traffic management to ensure safe, secure, and sustainable air travel at a global scale.”

With the advent of the Eurialo project, we stand on the brink of an exciting era of aviation surveillance, with the promise of improved safety, security, and efficiency in air travel. Only time will reveal the true impact and potential of this ambitious venture.
