T300 NTP Device Overview

TimeTools T300 is a GPS referenced hardware NTP server that can be used to accurately synchronize the clocks of networked computers.

TimeTools T300 NTP server device with GPS hardware clock.

The NTP device receives time stamps from the Global Positioning System (GPS) to precisely synchronize its internal real time clock. Client computers can then utilize the Network Time Protocol (NTP) over Ethernet to synchronize their system clocks to the correct time. When locked to GPS, the T300 can synchronize to within a few microseconds of UTC. Network time clients clocks can then be synchronized to within a millisecond of the NTP server.

The T300 can serve as a time reference for up to 100,000 client computers. Any networked appliance with NTP or SNTP client software can utilize the time reference. Most operating systems, routers, switches, phone systems and CCTV systems have NTP or SNTP protocols built-in.

Features

  • GPS referenced Stratum-1 NTP server.
  • Synchronize network time clients with millisecond precision.
  • Serves up to 100,000 client computers.
  • NTPv4 and SNTP compliant.
  • Dual stack IPv4 and IPv6 Internet Protocols.
  • Supplied with a high quality weather-proof T-3040 GPS antenna and mount.
  • Made in UK.

Timing Specification

  • GPS timing pulse synchronized to within 15 nanoseconds (one sigma) of UTC.
  • T300 system clock < 3usec locked to GPS.
  • Network time clients <1msec depending on network traffic.

Hardware Specification

  • Low-power, high-performance ARM processor.
  • Single 10/100 MBit auto-sensing, auto-MDIX Ethernet port.
  • Universal AC mains input PSU.
  • 1U high rack-mountable aluminium enclosure.

GPS Timing Receiver

The T300 integrates a GPS timing module which provides a precise pulse-per-second (PPS) output. When operating in Over-Determined Clock Mode the accuracy of pulse per second is within 15 nanoseconds of UTC.

Features

  • Works in the most demanding weak signal environments,
  • GPS Time Receiver Autonomous Integrity Monitoring (T-RAIM) algorithm.
  • High sensitivity.
  • Single satellite in view operation.
