How Galileo performed its authenticated positioning fix

Unread post by GPSrChive »

In a first for any satellite navigation system, Galileo has achieved a positioning fix based on open-service navigation signals carrying authenticated data. Intended as a way to combat malicious spoofing of satnav signals, this authentication testing began at ESA’s Navigation Laboratory — the same site where the very first Galileo positioning fix took place back in 2013.

These historic first authenticated signal position, velocity and timing fixes were made using a total of eight Galileo satellites for around two hours on Nov. 18. The tests represent a first proof of concept for an eventual operational service offering positioning with authenticated data to users.

“When a receiver picks up a navigation signal from a satellite, up until now it has no way of confirming that was indeed its source,” said navigation engineer Stefano Binda, overseeing the project for ESA. “This can result in spoofing — malicious people and organisations using false signals to mislead users about their actual position. This authentication service offers a way to prevent such deception.”
