CertifiedTime™ RF is a unique RF based service tied to the output of locally operated NIST DO type Atomic Clocks. These components are part of the NIST TMAS measurement system and track UTC(NIST) to somewhere in the 300 picosecond range.

This architecture makes CertifiedTime™ RF use as a 1PPS coordinating interrupt generation service a no-brainer. It also makes IRIG-B derived from that same source a no-brainer as a simple time service souring solution.Because of the local and long-line capabilities anyone anywhere can now get key IRIG or 1PPS over fiber as a key time service asset.

With CertifiedTime™ RF any corporate entity or securities sector operation can get direct access to the US Timestandard for their own private network control practice. The service is available everywhere Certichron operates Master Timing Centers across the Globe

The service is perfect for all users needing RF or 1PPS access to the master timescales we use.

Delivered How?

CertifiedTime™ RF is available over RF or optical transport providing absolute integrity and minimal if any tangible latency. This allows the reliance on the CertifiedTime™ RF service for absolute attestability in interrupt management for systems that are being used as a part of a transaction-recording service model. Likewise direct connections to UTC(NIST) over IRIG-B are simple with the Certichron Basic Clock Services System, the core of Certichron;’s next generation time-service centers.

Local and Back-Haul Access supported: Users in the Data Center can take copper coax or fiber cross connections on Multimode/Gradient Indexed fiber and those needing long-haul access, media converters are available for single-mode dark fiber scenarios.

Immune: With this RF service sub-microsecond IRIG as well as 1 PPS and 10MHz are available as key trust-anchor resources. RF based time services are generally immune from many of the Internet security and network latency issues making them easier in some instances to deploy and qualify than most all other solutions.
