First Galileo OSNMA Position authenticated with GOOSE© using live signals!


Since Nov 15, 2021, the long-awaited Public Observation Test Phase for Galileo OSNMA (Open Service Navigation Message Authentication) is finally live!
Interested users can sign up for this test phase on the GSC’s website and get access to all corresponding documents and information, including the current ICD, the receiver guideline, as well as the OSNMA public key and Merkle Tree Root which are needed for the authentication process.

In late 2020 and the first half of 2021, TeleOrbit GmbH and Fraunhofer IIS worked on a project to implement the Galileo OSNMA capabilities onto their Powerful and Compact GNSS Receiver Lab “GOOSE”.
This project successfully authenticated simulated OSNMA signals and was completed in May 2021.

Now, the team at Fraunhofer IIS adapted their setup to the newly published ICD and receiver guideline and was able to authenticate the live signal on Tuesday, November 16, 2021, see LinkedIn screenshot below (cropped).
