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
NETWORK COMPATIBILITY
• Supports NTP, DHCPv4, DHCPv6 for auto acquisition of
network address, name servers, timeserver configuration
• Telnet/SSH communication
• IPv4/IPv6 compatible
CONFIGURATION
• Configure devices through provided WinDiscovery or SSH
• Configuration is saved to nonvolatile memory and
survives power losses
• Authenticated network messages prevent unauthorized
tampering of clock configuration
ANTENNA
• Optional weather-proof, pre-amplified antenna included
with 16 ft (5 m) of coaxial cable
• Optional antenna kit is available with antenna, 50 ft
(15 m) cable and antenna

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.
