CAST Releases Two New Technical Bulletins on Clock Holdover
The Center for Alternative Synchronization and Timing has published the first two technical bulletins in a series on atomic clock holdover. “Holdover” occurs when a clock is disconnected from its stable reference source. In many, if not most, cases, deployed clock implementations will utilize GPS (or other GNSS) as the reference source to ensure the time distributed by the deployed clock is synchronized with UTC. Absent this connection, a clock will be in holdover, and will be subject to deviating from that authoritative source. These holdover experiments will assess the performance of different types and configurations of atomic clocks to understand their stability and effectiveness in holdover, and how long it takes for a clock’s accuracy to degrade to a point exceeding usefulness for power grid applications.
