Europe has achieved a groundbreaking milestone in satellite navigation security with the official launch of Galileo’s Open Service Navigation Message Authentication (OSNMA) on July 24, 2025. This pioneering service makes Galileo the world’s first Global Navigation Satellite System (GNSS) to offer free, worldwide authentication capabilities, addressing the escalating threat of GNSS spoofing attacks that have increased by 400% in recent months.
Through our products, you leverage OSNMA’s security
At SBG Systems, we have been preparing for this moment. From the earliest technical announcements, we anticipated the critical role that signal authentication would play in protecting positioning infrastructures.
Our product line comes OSNMA-ready to ensure that customers in oil & gas, energy, and other critical sectors can operate in the harshest GNSS environments with confidence in the authenticity of their Galileo signals.
With OSNMA integrated into Galileo’s E1-B signal, our navigation systems can now verify the legitimacy of broadcasted data, making spoofing attacks far less effective. This means that your operations—whether at sea, overland, or in complex industrial environments—are protected by the most advanced GNSS authentication technology currently available.
OSNMA is cryptography-based
OSNMA works by embedding cryptographic signatures in Galileo E1-B navigation messages. According to EUSPA, every Galileo satellite now broadcasts digitally signed navigation data, allowing compliant receivers to validate the source and integrity of the signal in real time.
This authentication process helps ensure that users—from pilots to field operators—receive trusted Galileo signals, even in regions with a high risk of interference or malicious attacks.
For more detailed information about the OSNMA service characterization, potential target markets, and roadmap, you can check here the official documentation released by EUSPA.
What it means for the industry?
The navigation technology market is experiencing unprecedented growth, with the autonomous navigation sector projected to reach $9.4 billion by 2032 and GNSS augmentation services expected to double to $6 billion by 2030.
Industry experts emphasize that OSNMA’s free availability and backward compatibility make it accessible to low-cost receivers through simple firmware updates, facilitating widespread adoption across consumer and professional applications.
As cyber threats against satellite navigation continue to intensify, Galileo’s authentication service represents a crucial step toward securing the digital infrastructure that powers modern transportation, logistics, and positioning-dependent technologies worldwide.
This launch reflects EUSPA’s vision to protect end users free of charge, enhance the resilience of global navigation, and strengthen trust across industries reliant on GNSS. We at SBG Systems are proud to support this historic development, ensuring our clients benefit from the most advanced, trustworthy navigation available, wherever their missions take them.
