Timing Sources for Wireless Carriers, Critical Infrastructure Bolstered Against GNSS Jamming and Spoofing

Microchip Technology Inc. integrated its BlueSky GNSS Firewall with its TimePictra 11 synchronization monitoring and management platform to protect 5G networks and other critical timing infrastructure from GPS jamming and spoofing while providing single-console visibility across the entire timing architecture.

5G wireless infrastructure has more complex, higher-density synchronization needs than previous-generation networks and is highly dependent on the integrity of live-sky GNSS timing signals.The TimePictra system improves overall situational awareness by managing network timing synchronization as well as Microchip’s GNSS firewall for network resilience through real-time GPS threat detection and mitigation, according to the company. TimePictra monitors GNSS-based source clocks along with Microchip’s network-based timing distribution solutions to deploy a resilient timing architecture for wireless carriers’ 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 TimeProvider 4100 grandmasters for 5G network synchronization. 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.
