The virtual Primary Reference Time Clock or vPRTC is a highly secure and resilient timing architecture with advanced monitoring and control capabilities to deliver protected timing over high-speed optical networks.
- GNSS is the source of UTC-traceable time at protected core-timing sites. BlueSky™ GNSS firewall monitoring assures GNSS is validated and protected from potential cyberattacks such as jamming or spoofing.
- High-precision atomic clocks provide long-term stability to hold time independently from GNSS. Fully autonomous atomic clocks are the heartbeat of vPRTC resiliency.
- GNSS plus atomic clocks combine to establish an autonomous timescale that can hold and distribute time for critical infrastructures using advanced IEEE®1588 Precision Time Protocol systems.
Learn more about how the vPRTC timing architecture delivers highly secure 100 nano second level timing over optical networks to support critical infrastructure timing needs in transportation, power utilities, 5G and data center applications.
