On July 24, 2025, Europe reached a major milestone in satellite navigation security with the launch of Galileo’s Open Service Navigation Message Authentication (OSNMA).
Galileo is now the first Global Navigation Satellite System (GNSS) to provide free authentication worldwide. Meanwhile, the service counters the growing risk of spoofing attacks, which have surged by 400% in recent months, according to the Zurich University of Applied Sciences and SkAI Data Services (2024).
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 is OSNMA-ready, giving oil & gas, energy, and other critical sectors reliable operation even in challenging GNSS environments. With OSNMA built into Galileo’s E1-B signal, our systems verify broadcast data and block spoofing attempts.
This ensures secure operations at sea, on land, or in complex industrial sites—protected by today’s most advanced GNSS authentication technology.
OSNMA is cryptography-based
The service works by embedding cryptographic signatures in Galileo E1-B navigation messages. Moreover, according to EUSPA, every Galileo satellite now broadcasts digitally signed navigation data. This enables 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 market is expanding rapidly. The autonomous navigation sector may reach $9.4 billion by 2032 (Fortune Business Insights, 2025). GNSS augmentation services are expected to double to $6 billion by 2030 (Metastat, 2024).
OSNMA’s free availability and backward compatibility make it easy to adopt, even on low-cost receivers with firmware updates. This accelerates use across consumer and professional navigation solutions.
With cyber threats rising, Galileo’s authentication service is a critical step in protecting the infrastructure behind transport, logistics, and positioning technologies. The launch reflects EUSPA’s commitment to resilience, end-user protection, and global trust in GNSS.
At SBG Systems, we proudly support this milestone, ensuring our clients have secure, dependable navigation wherever their missions take them.
