Time Reference
• When synchronized to atomic clocks in GPS
satellites the long term accuracy of the NTP100 is
the same as the atomic clock of the GPS
• After initial synchronization and (if) upon loss of
GPS signal the NTP100 will revert to an internal
temperature compensated crystal oscillator and
typically maintain accuracy of <165 ms per day.
