NTP100-GPS NTP Server


Overview

Network Time Protocol (NTP) Server 

The NTP100-GPS network protocol time server (NTP) from Masterclock synchronises to GPS satellites and sends NTP reference signals to NTP devices via Ethernet.

When synchronised 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, and an optional OCXO (oven-controlled crystal oscillator) increases holdover stability to ± 250ms/year. 
 

 

Technical

  • 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

Specifications

Holdover Accuracy

  • With loss of power, device reverts to an internal precision TCXO temperature-compensated crystal oscillator with accuracy of ± 1min/year or < 165ms per day
  • High-stability option with OCXO provides typical stability of 1 ppb/ day (± 250ms/year) after 30 days of aging
