Accessories and Services
We offer many accessories and services for our cesium products. We also offer products designed to extend the life of your unit, and we can assist with disposal of your cesium reference at the end of its life.
Applications
Critical Infrastructure
Cesium frequency references are widely deployed as the primary source of time and frequency in a broad range of applications, including timing and metrology, defense, Position Navigation and Time (PNT) systems, telecommunications, data centers and critical infrastructure.
Coordinated Universal Time (UTC)
UTC is the global standard for the time of day. It is used to synchronize power grids, cell phone networks and satellite communications across the world. The time is created by a weighted average of approximately 400 atomic clocks located around the global. In the June 2022 UTC report (Circular T), we had 226 cesium clocks contributing to UTC, representing 99% of all cesium clocks in the ensemble.
