How Galileo performed its authenticated positioning fix
News from the European Space Agency (ESA)
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.
Septentrio, a company based in Belgium that designs GPS/GNSS positioning technology, announced that its receiver has successfully authenticated navigation data of the first OSNMA-encrypted GNSS satellite signal. OSNMA Open Service Navigation Message Authentication is being pioneered by Europe's Galileo program and

Anti-Jamming and Anti-Spoofing Crucial to Cyber Security
BELGIUM – WORLDWIDE – Leuven headquartered Septentrio, which specialises in high-precision Global Navigation Satellite System (GNSS) positioning solutions, announced today that its receiver has successfully authenticated navigation data of the first OSNMA encrypted GNSS satellite signal. OSNMA (Open Service Navigation Message Authentication) offers end-to-end authentication on a civilian signal, protecting receivers from spoofing attacks.
OSNMA is being pioneered by the Galileo Programme, with Septentrio providing a test bed for this technology from the end-user point of view. GNSS include such as the American GPS, European Galileo, Russian GLONASS, Chinese BeiDou, Japan’s QZSS and India’s NavIC. These satellite constellations broadcast positioning information to receivers which use it to calculate their absolute position and can
In a first for any satellite navigation system, Galileo has achieved the first position fix based on navigation signals carrying authenticated data, according to the European Space Agency.
Galileo’s Open Service Navigation Message Authentication (OSNMA) is intended as a way to combat malicious spoofing of satnav signals.
OSNMA receivers successfully calculated an OSNMA-protected position fix after Galileo satellites started transmitting authentication data at 15:28 UTC on Nov. 18, 2020. The first tests used eight Galileo satellites for around two hours on Nov. 18. Tests have continued ever since, for intermittent periods, and will continue over the next months ahead of a public observation phase.
TeleOrbit GmbH of Nuremberg, Germany, announced that it has implemented testing capability for Galileo’s Open Service Navigation Message Authentication (OSNMA) aboard the company’s GNSS Receiver with Open Software Interface (GOOSE).
As the threat of GNSS spoofing continues to grow, authentication of signals represents a safeguard for industry, vital infrastructure and safety-critical GNSS applications, including autonomous vehicles. As yet there is no authentication service available, but Galileo will be first to the market with scheduled launch in 2023. The European Space Agency (ESA) and the European GNSS Agency (GSA) will soon start an initial testing phase.
“We will be one of the few out there who have this feature enabled in a receiver, so for anyone interested in using signal authentication in their research or products, we have a well-proven, well-tested receiver on the market,” said Daniel Seybold, TeleOrbit COO. “We have received initial feedback from first custo
