A research team at the Fraunhofer Institute for Integrated Circuits (IIS) in Germany authenticated Galileo’s live Open Service Navigation Message Authentication (OSNMA) signal on November 16. The team used a GNSS receiver jointly developed with TeleOrbit GmbH, the compact GNSS Receiver with Open Software Interface (GOOSE). A screenshot below shows the results of the signal reception for GPS + Galileo authenticated Galileo PVT.
The Public Observation Test Phase for Galileo’s OSNMA was opened for live testing on November 15. Interested users can sign up for this test phase on the European GNSS Service Centre’s website and get access to all corresponding documents and information, including the current interface control document (ICD), the receiver guideline, and the OSNMA public key and Merkle Tree Root which are needed for the authentication process.
The GOOSE receiver successfully authenticated simulated OSNMA signals in May 2021.
