Galileo has started testing Open Service Navigation Message Authentication (OSNMA) in the signal-in-space, allowing the first-ever OSNMA-protected position fix to be successfully computed. Testing will continue over the next months, ahead of a so-called “public observation” phase. This is the first-ever transmission of authentication features in open GNSS signals of a global navigation system.

OSNMA test signals are being broadcast by the Galileo constellation

The Galileo OSNMA is an authentication mechanism that allows GNSS receivers to verify the authenticity of GNSS information, making sure that the data they receive are indeed from Galileo and have not been modified in any way. Read more…
