Enabling resilient timing for critical infrastructure

Today’s 5G wireless infrastructure has more complex, higher-density synchronisation needs than previous-generation networks and is highly dependent on the integrity of ‘live-sky’ timing signals from the Global Navigation Satellite System (GNSS).

“Microchip’s TimePictra system improves overall situational awareness by managing network timing synchronisation as well as our GNSS firewall that improves a network’s resilience through real-time GPS threat detection and mitigation,” said Randy Brudzinski, Vice President, Frequency and Time Systems business unit. “Our solution’s scalability is particularly valuable for mobile operators who can use TimePictra to monitor GNSS based source clocks along with our secure network-based timing distribution solutions to deploy a highly resilient timing architecture for their transition to 5G.”

In addition to requiring precise timing from GNSS sources, critical infrastructure operators need accurate timing to be distributed across their networks so they can ensure reliable performance and service delivery. TimePictra provides full control and monitoring for resilient timing architectures created with Microchip’s broad product portfolio including its TimeProvider 4100 grandmasters for 5G network synchronisation.

It also monitors the health and performance of these networks’ distributed Precision Time Protocol (PTP) client clocks. Integrating BlueSky GNSS Firewall management into the TimePictra console view now gives operators a unified picture of the entire timing architecture and all timing sources.

Beyond supporting 5G deployments, TimePictra enables aviation, railway and maritime ports with a regional, national or global view of GNSS reception. TimePictra in combination with BlueSky GNSS Firewalls monitor key GNSS observables to detect live sky signal anomalies and deliver early alerting so that operators can engage alternate procedures that do not rely on GNSS. These capabilities are increasingly important where public safety is dependent on the position and navigation for daily operations.

Microchip’s TimePictra timing infrastructure management system with its Blue Sky GNSS Firewall is available today.
