Nanosecond level Synchronization for Distributed Timing Networks

Microchip Technology has introduced its new SkyWire time measurement technology, designed to deliver nanosecond-level synchronization and verification for large-scale, distributed timing networks. Embedded in the company’s BlueSky GNSS Firewall against spoofing and jamming of navigation systems, SkyWire extends precise time traceability from metrology labs to critical infrastructure operators across vast geographic areas. This development provides a practical solution to a growing challenge in power grids, telecom networks, data centers, and financial systems — ensuring that clocks across dispersed systems remain tightly synchronized and traceable to authoritative standards such as Coordinated Universal Time (UTC).

Nanosecond precision across long distances

The BlueSky GNSS Firewall 2200 with SkyWire technology allows geographically separated timing systems to measure and align clocks with nanosecond precision, even over long distances. Traditionally, this level of synchronization was achievable only between national metrology labs or research institutions. Microchip’s commercial solution brings that capability to operators of mission-critical networks such as air traffic control, energy utilities, and financial services.

“With the new SkyWire technology solution, we’re making UTC more widely accessible so that large deployments of clocks can be independently measured and verified against each other across long distances,” said Randy Brudzinski, corporate vice president of Microchip’s frequency and timing systems business unit.

Traceability beyond metrology labs

SkyWire builds on the National Institute of Standards and Technology (NIST) Time Measurement and Analysis Service (TMAS), which supports organizations that must maintain accurate local time standards. By integrating SkyWire within the BlueSky Firewall, Microchip offers a commercial off-the-shelf (COTS) solution that allows customers to connect with NIST’s TMAS Data Service for large-scale clock verification.

Microchip’s approach also allows other nations and metrology institutions to replicate this capability using the company’s TimePictra software suite, which delivers similar functionality to the NIST TMAS Data Service. By combining the BlueSky GNSS Firewall 2200 and TimePictra, operators can deploy an end-to-end solution for time measurement, alignment, and verification within their own national or enterprise infrastructures.
