The ePRTC360+ safeguards at-risk critical power grids, transportation, aviation and public safety systems, 5G mobile networks and AI data center infrastructure against the increased threat of GNSS timing disruptions.
Benefits
- Affordable, patent-pending Cesium-less ePRTC360+ clock solution
- Resilient GEO holdover signals, successfully tested in real-world jamming and spoofing environments
- Distributed ePRTC360+ clocks across core/midhaul/edge networks, boosting sync network robustness and holdover reliability via meshed PTP backup feeds between clocks
- Rapid, easy deployment eliminating Cesium clock constraints
- Seamless replacement of an end-of-life Cesium clock at the core with multiple distributed ePRTC360+ clocks across the network—all at the same cost of a single Cesium clock
