🔐 How does a GNSS receiver determine whether a satellite signal is truly authentic? ➡️ GNSS is indispensable today—but satellite signals can be disrupted or manipulated through spoofing.

🔵 The problem:
A receiver may calculate an incorrect position without realizing that the navigation data has been manipulated. For autonomous systems or critical infrastructure, this can have serious consequences.

🟠 The solution:
OSNMA (Open Service Navigation Message Authentication) enables the cryptographic authentication of Galileo’s navigation messages. This allows the receiver to verify that the data is genuine and unaltered.

💡 The Benefit
OSNMA does not make GNSS more accurate, but it does make it more trustworthy—an important foundation for secure and robust navigation. Combined with sensor fusion and integrity monitoring, it provides additional reliability.

🟠 At ANavS, we offer solutions for secure and robust navigation—through the intelligent combination of GNSS, sensor fusion, and integrity monitoring.
