Adtran has launched new synchronization solutions featuring Satellite Time and Location (STL) technology to address the growing vulnerabilities of GPS and other GNSS systems to jamming and spoofing attacks.

The OSA 5405-S PTP grandmaster clock can now receiveSTL signals, and the OSA 5400STL module also incorporatesSTL receiver technology.

The dual-source approach aligns with zero-trust principles, ensuring resilience even in the event of GNSS disruption.
