Description

Combining WhiteRabbit with AtomiChron HA (High Accuracy) real-time PPP GNSS service, allows for WhiteRabbit links to extend beyond the need for Fiber Optic availability and connect WR networks anywhere in the world. Real-time PPP enables WR links by jumping any distance at similar performance levels to WR. Besides this possible hybrid approach combining the 2 technologies, the UTC(k) reference will be able to real-time align any node in the system to UTC(PTB) or UTC(NIST) with other UTC(k) labs to follow to sub-ns accuracy. Last but not least, real-time PPP is able to calibrate and monitor WR links, independent from the Fiber Optic network. Improving resilience, because, let's be honest, GNSS might not be 100% reliable, but neither are FO links!

We'll present measurement data from our recent measurement campaign with PTB, RI.SE and Deutsch Telekom, showcasing the performance of the UTC(k) as well as the underlying real-time PPP service based on COTS hardware. Please note that it's a proposal to combine the two technologies, it hasn't been carried out yet. I will prove what we can do though supported by measurements.
