Description:
Accuracy, precision and stability have traditionally been used to describe the requirements for timing and synchronization. Although these timing metrics remain vital, a new set of requirements have become equally important with the goal of delivering better resiliency in critical infrastructure: prevention, restoration and recovery. A variety of technologies are being discussed to create a back-up to GNSS. The answer to greater resiliency does not lie in the number of timing sources, but rather in a timing architecture that incorporates these technologies. This presentation will discuss how a Virtual Primary Reference Timing Clock (vPRTC) architecture is optimized for resilient timing.

You will learn:

• An overview of the use and dependencies upon GNSS timing for critical infrastructures
• Understanding key new protection-enabling standards that designers of critical infrastructure should be aware of
• New design principles for a timing distribution architecture that provides protected and resilient timing
• Definition of the vPRTC architecture and the role of protected GNSS, atomic clocks and high-precision IEEE® 1588 PTP timing distribution
• Applications and industries that have deployed the vPRTC architectures
