Resilient Positioning, Navigation and Timing for 5G networks

Resilient Positioning, Navigation and Timing for 5G networks

Viavi Solutions has launched a more compact system for Positioning, Navigation and Timing from the acquisition of Jackson Labs last year.

The PNT-6200 Series Assured Reference can supplement or even replace GPS signals in Low Earth Orbit (LEO), GNSS, commercial satellite, terrestrial, wireline, and atomic clock services.

When plugged directly into the antenna port of the timing receiver, the PNT-6200 Series takes the timing signal from the most reliable source and converts it to a radio frequency (RF) signal as a direct replacement for the GPS input, seamlessly enabling continuous operation.

This is increasingly important as networks become dependent on disaggregated, cloud-native architectures where traditional methods of positioning and timing become less reliable. These networks are also increasingly susceptible to threats of spoofing and jamming and these issues can disrupt operations in a range of environments, from aircraft instrument landing systems to timing and synchronization in mobile networks.

With Private 5G networks rolling out across factories and enterprises, resilient PNT will be critical to enable efficient deployment and robust cybersecurity. When installing 5G systems indoors via microcells, access to GPS for timing synchronization becomes difficult or impossible, and placing an antenna on the roof of the building may not be feasible.

With indoor reception, and fully GNSS-independent timing and positioning capability world-wide, the small form factor and diversity of signal sources enable the PNT-6200 Series to effectively address these challenges.

“Almost immediately after we joined Viavi, we have been able to take advantage of the superior scale of the company, from sales force to supply chain,” said Said Jackson, Founder, Jackson Labs, and Vice President, Viavi. “Now, we are excited to bring the power of resilient PNT to more markets that Viavi serves, including telecommunications, avionics and mission-critical infrastructure.”

Jackson Labs launched a larger version, the PNT-6220, in 2020.
