GPS NTP Server Applications

  • Accurately synchronize Windows, Linux and many other network devices.
  • Ideal for CCTV, DVR and Video Management Systems.
  • Access Control Systems.
  • Network timing, measurement and synchronization.
  • SCADA, Automation and Control Systems, Network Monitoring.
  • Legally-traceable time source inside your firewall.
  • Reference for NTP clocks and time displays.

High Performance, High Reliability, Low Power

The high performance microprocessor used in the T300 allows the device to synchronize up to 2 million network time clients at default NTP polling frequencies. Even more clients can be served by reducing client polling rates.

With a LINUX kernel, TimeTools T300 is based on a high-performance industrial processor module with exceptional reliability. The unit requires no cooling fans and has no other moving parts. It has very low power consumption and runs cool, aiding reliability and longevity.

Network Protocols

The T300 can provide time to any NTP or SNTP compatible client or device. Windows servers and workstations, Linux, network switches and routers can all obtain time from the T300. Additionally, the latest NTPv4 protocol is fully backwards compatible with previous versions of NTP.

Configuration is achieved by an easy to use web interface. The T300 also supports the following protocols: HTTPS, HTTP, SSH, SCP, SNMP v1/v2c/v3, SFTP, FTP, DHCP, DHCPv6. Additionally, both IPv4 and IPv6 internet protocols are supported.

Microsecond Precision

The GPS timing receiver integrated into the T300 provides timing information to within 15nsecs of UTC when locked to a GPS signal. This allows the NTP daemon running on the devices Linux PPS kernel to synchronize within 3 microseconds of UTC.

Flexible Installation Options

The high-specification GPS timing receiver integrated into the T300 can continue to provide precise timing in the most challenging environments. By default, the device operates in a static-positioning mode allowing single-satellite timing. This allows the possibility of locating an antenna in a window or on the side of a building.

The GPS receiver also supports a high-sensitivity mode which allows indoor signal reception in many installations. These features combine to provide installation cost savings compared to traditional GPS systems.

Of course, the T-3040 GPS antenna supplied with the T300 is completely weather-proof and can be roof-mounted, if required, to provide a reliable, consistent signal lock.

T-3040 High-Gain Permanent-Mount GPS Antenna

T-3040 GPS NTP Server High-Gain Timing Antenna

The T300 is supplied with the high-gain permanent-mount T-3040 GPS timing antenna. The antenna covers the civilian GPS L1 frequency band and provides exceptional multipath rejection, out-of-band signal rejection and circular polarized signal reception.

Also, the antenna provides consistent response in all operating temperatures and excellent signal-to-noise ration. Additionally, with an attenuation of 40dB, long cable runs can be accommodated without problems.

The antenna housing is fully weather-proof and can be used in indoor or outdoor installations. The supplied antenna mount provides flexible installation options by providing secure fixing to a flat surface, wall or mast.
