Galileo to be the first GNSS to offer authentication service worldwide with launch of OSNMA

Coming at a time when attacks on GNSS signals, such as spoofing, are on the rise, OSNMA provides a critical layer of protection. Spoofing involves the transmission of counterfeit satellite signals that deceive GNSS receivers, potentially resulting in false and unreliable positioning. These events can affect critical applications in transportation, finance, telecommunications, information technology, energy, utilities, manufacturing, health services, emergency services and law enforcement, in which GNSS, and in particular Galileo, is used. In sectors such as aviation or maritime, this can lead to serious safety risks. The Galileo OSNMA mitigates these threats by allowing users to confirm that the data they receive is genuinely from Galileo and has not been tampered with. It works by embedding cryptographic data, or a digital signature, into the navigation message (I/NAV) broadcast on the E1-B signal.Because the OSNMA is transmitted in the Galileo Open Service signal, which is already used in most devices, receivers only need to implement the protocol and download the certified public keys from the European GNSS Service Centre (GSC) website. OSNMA service relies as well on the imp...
