Let's dive deeper - SATERA objectives
Automatic Dependent Surveillance-Broadcast (ADS-B) is a surveillance technology in which airborne
equipment automatically broadcasts aircraft location to ground stations.
Unfortunately, it has some drawbacks related to the use of Global Navigation Satellite Systems (GNSS) data and the use of open protocols, and usually a secondary independent surveillance system is needed.
Conventional ground-based independent surveillance systems such as primary or secondary radars are rarely available over oceanic and uninhabited areas.
SATERA’s primary objective is to develop and validate a concept for a space-based
multilateration (MLAT) system that uses ADS-B signals. By leveraging a constellation of Low Earth
Orbit (LEO) satellites, this system will combine advanced techniques like Time-of-Arrival (ToA),
Angle-of-Arrival (AoA), and Frequency-of-Arrival (FoA) measurements to localize
aircrafts using enhanced multilateration algorithms.
This innovative approach will cross-check the positional data provided by ADS-B systems with
independent measurements. SATERA also includes developing robust
architectures for satellite receiving systems and exploring inter-satellite communication solutions
to ensure seamless performance.
Through these advancements, SATERA will set the foundation for a safer, more secure, and
resilient air traffic surveillance network.
