Public Stratum 1 NTP server, southeast New Brunswick, Canada.

tick.lntgn.ca provides an alternate network path to the ntp.lntgn.ca hardware.

Dual-band L1/L5 GNSS antenna, 20 dB LNA, distribution splitter, u-blox NEO-M9N. PPS fed directly to an Intel I210 SDP pin, hardware-timestamped by the NIC, used to set the PHC. System clock derived from PHC via phc2sys, served by chrony. Root dispersion typically under 2 microseconds.

My other Stratum 1 projects: BeagleBone Black PRU PPS timestamping, ESP32 NTP server using motor control peripheral to capture PPS and Wiznet to hwts NTP.
