Symmetricom — Clocking In...

Symmetricom(R), Inc., a supplier of precise time and frequency technologies, has announced the Time-Scale System, a fully integrated world-class redundant nanosecond level timing solution. Designed for international metrology, aerospace and defense customers, the system combines multiple high-performance atomic clocks in a time scale that drives a local real-time clock (RTC).

Comparable to the world's best national laboratories that compute a local time scale steered to agree with Universal Coordinated Time (UTC), the Time-Scale System is ideal for national timing laboratories in countries that need to establish traceable time. It is also designed for government or civilian agencies that require precision timing capabilities independent of a Global Navigation Satellite System (GNSS). The Time-Scale System's unique set of design features enables industry-leading frequency stability, phase-noise performance and reliability in a system fully integrated into one or more instrument racks. A timing quality GNSS receiver provides information used to steer the system output to UTC and generates common view data so that the multiple clocks can be reported to the International Bureau of Weights and Measures (BIPM) for inclusion in the international time scale. The system can also be steered to UTC using two-way satellite modems.
