Septentrio successfully authenticates OSNMA data for GNSS

LinkedIn +

High-precision GNSS positioning solutions developer Septentrio has announced that its receiver has successfully authenticated navigation data of the first OSNMA-encrypted GNSS satellite signal. Open Service Navigation Message Authentication (OSNMA) offers end-to-end authentication on a civilian signal, and is aimed at protecting receivers from spoofing attacks.

OSNMA is being pioneered by the European Space Agency’s (ESA) Galileo Program, with Septentrio providing a testbed for the technology from the end-user point of view. According to the company, the anti-spoofing capabilities of OSNMA will complement Septentrio’s anti-jamming technology, AIM+, and further strengthen the overall security of Septentrio GNSS receivers.

“The authentication of the Galileo signal using the OSNMA technology is yet another ‘first’ that we are pleased to share with our close partner ESA,” commented Bruno Bougard, R&D director at Septentrio. “Septentrio is proud and thankful to be able to contribute to the realization of one of Galileo’s key differentiators.”

ESA and the European GNSS Agency (GSA) have now commenced the testing phase of the OSNMA authentication, which will continue over the coming months.
