Adtran‘s Oscilloquartz synchronization platforms now support Galileo’s Open Service Navigation Message Authentication (OSNMA). OSNMA is a GNSS authentication service designed for civilian use.
By verifying that timing data originates from genuine Galileo satellites, OSNMA ensures authenticity and integrity at the point of reception. The new feature, available via firmware update for supported multi-band GNSS receivers, adds an extra layer of protection against spoofing and manipulation, empowering existing deployments to strengthen security without hardware changes or service disruption.
OSNMA support from Adtran brings a new level of GNSS security to critical infrastructure. Available for multi-band GNSS receivers in the OSA 5412, OSA 5422, OSA 5430 and OSA 5440 product lines, the feature integrates with Galileo’s Open Service, using digital signatures and TESLA chain keys to authenticate navigation data. This ensures that timing and positioning information is verified as authentic and protected against spoofing or manipulation.
Adtran’s Oscilloquartz Syncjack probing adds a second layer of defense, detecting record-and-replay attacks – also known as meaconing – by comparing GNSS signals against trusted PTP sources. This dual-layer approach helps identify subtle timing manipulations and delay attacks that traditional receivers may miss.
“From 5G and smart power grids to financial networks and data centers, bringing authentication to GNSS is a game changer for critical infrastructure,” said Gil Biran, GM of Oscilloquartz, Adtran. “By enabling our customers to defend against sophisticated threats, including meaconing, we’re helping them achieve greater timing integrity for their networks. Existing customers can access this new GNSS security feature with a simple firmware update, helping them stay protected as threats continue to evolve.”
