Commercial Time Scale System
Fully Integrated, World-Class Turn-Key Timing System
Symmetricom’s multi-clock turnkey system provides a real-time local UTC time scale and can also apply the most accurate GNSS and SatCom techniques for measuring offsets between geographically dispersed clocks.
As the international standard time scale, Universal Coordinated Time (UTC) is the composite of clocks throughout the world. The time of each clock is reported to the International Bureau of Weights and Measures (BIPM) using either GPS common view (CV) or Two-Way Satellite Time and Frequency Transfer. National laboratories also compute a local time scale steered to agree with UTC designated as UTC(local). Local UTC time-scale systems have state-of-the-art frequency stability, phase noise performance, and system availability. To be incorporated in UTC, their internal clocks cannot themselves be steered by UTC and the CV data must be calculated and reported to the BIPM in accordance with its published method and format.
The Symmetricom Time-Scale System meets these requirements using Symmetricom manufactured commercial timing products. Compared to other solutions, Symmetricom offers faster deployment, lower ownership costs, higher product quality, spare parts that are easier and less expensive to get, and a single point of responsibility for all system support.
