ePRTC360+ Enhanced Primary Reference Time Clock

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.

The ePRTC360+ is a Cesium-less enhanced Primary Reference Time Clock solution engineered to maintain precise timing through GNSS jamming and spoofing.

Traditional ePRTC deployments rely on costly and operationally complex Cesium clocks that are difficult to scale beyond the network core. The ePRTC360+ removes these barriers by delivering Cesium-class holdover performance without Cesium hardware, enabling resilient timing even in GNSS-contested environments.

Successfully tested in real-world defense and commercial GNSS jamming and spoofing environments, the patent-pending ePRTC360+™ solution delivers <±100 ns holdover accuracy for over 360 days—with no time limit thereafter. It provides a resilient, affordable, and easy-to-deploy alternative across synchronization networks, from core to midhaul to edge.

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
