NTP100-GPS

Stratum 1 NTP server locked to GPS satellites for legally traceable time-stamping.


The NTP100-GPS is an NTP (Network Time Protocol) server that synchronizes to GPS satellites and distributes NTP reference signals via Ethernet. When synchronized to the atomic clocks in GPS and GLONASS satellites, the long term accuracy of the device is the same as the atomic clock of the GNSS. An internal TCXO (temperature-compensated crystal oscillator) provides holdover stability of ± 1 min/year during GPS signals loss. An optional OCXO (oven-controlled crystal oscillator) increases holdover stability to ± 250ms/year. 


  • Provides time legally-traceable UTC
  • NTP output accuracy of ± 2 ms
  • Synchronized to atomic clocks in GPS satellites for Stratum 1 accuracy
  • Typical holdover stability of ± 1 min/year using high precision internal TCXO during GPS loss
  • High-stability option with OCXO provides typical stability of ± 250 ms/year
  • Time stamp precision of 5-10 ms
  • NTP query (unicast), multicast, or broadcast modes
  • Assignable network configuration
  • Configuration via Telnet/SSH or included WinDiscovery
  • IPv4/IPv6 compatible
  • MD5 authentication

 

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
