Offices of Measure use NTP servers in configuration where only frequency is locked on 1PPS available from 5071A atomic caesium clock. Elproma has developed new NTP driver to support 5071A timestamps via both 1PPS frequency and UTC Timestamps. This configuration does not need GPS or other remote NTP server any more. Elproma NTP server now uses simultaneously combination of 1PPS and Timestamps (rs232) from 5071A. Independently you can still trace caesium on your PC due to monitoring information goes through Elproma NTP server, which behaves transparent for PC requests.
