Local stratum 1 GPS NTP time server, yay! Now to see how it copes with sun and rain. The bag is an extra precaution. Tracking 36 satellites and using 19, over three networks. Current PPS tracking with σ=16ns Current jitter measured at FireBrick (NTP client) of 0.08ms, and latency of 0.7ms. Selected over any pool (via Internet) servers, understandably.

“Swinburne University #Professor #AllisonKealy, an expert in #positioning, #navigation and #timing, told the ABC she had raised this exact scenario when she approached Telstra earlier this year while seeking support for a proposed critical #infrastructure #resilience #research centre. Professor Kealy said the pitch to #telcos and other critical infrastructure operators was that they needed to identify shared points of failure before an outage exposed them.” "We have been approaching all the critical infrastructure sectors to tell them, we have to act now," Priorities set by Business leaders and Politicians VS Academics and Engineers. #NTP / #GPS / #telecommunications / #Swinny / #SwinburneUniversity

Der NTP-Bug in fr24feed, der meinen ADS-B-Feeder wochenlang offline gehalten hat, ist in 1.0.57 endlich weg. Flightradar24 hat den kaputten NTP-Client nicht repariert, sondern rausgeworfen und die Zeitsynchronisation an systemd-timesyncd übergeben.
