NTP GPS TIME SERVER
GPS NTP Server is a network appliance designed to obtain very accurate time information from the GPS satellite positioning system and synchronize a network of time clients.  
The new model SISTEK 1N-NTP Industrial Grade GPS NTP Time Server that we manufactured are   specifically for Servers and Personnel Computer, automatization system, telecom system, traffic system that need high-precise time require. Our system is based on GPS, and the precision of NTP time output is 100ns and receive accuracy can be 1ms and IRIG-B 1us. It can track 12 GPS satellites at the same time, and selects the best satellite automatically for locating and timing. It outputs UTC time and IRIG-B time codes and the synchronous precision is 1µs.The SISTEK 1N-NTP is quite cost effective and high quality, its highest record of MTBF is 12 years.   

NTP GPS TIME SERVER

  • Technical Description

    • Receiving frequency: 1575.42MHZ, it can track 8-12 GPS satellites at the same time.
    • Antenna radio sensitivity: -166dbw, with 30 meters wire .If the wire is not long enough, customer can prolong it by himself by selection of coaxial-cable that attenuation of 1.56GHZ is not more than 0.7db per meter, the attenuation of prolonged cable is not more than 5db.
    • Capture time: from 20 seconds to 2 minutes ( the outputs of synchronous clock are all isolated by photo electricity coupling and output 60ns)
    • Industry frequency clock: the clock that is promoted by industry electricity is synchronous with standard clock when power is on．
    • Clock difference: that is standard clock minus industry frequency clock, synchronous time difference is zero precision is 20 ms.
    • Longitude, latitude, altitude: where the electric power synchronous clock locates.
    • Display: 14 bits LCD display
    • Time Codes Output: 1or 2xNTP/SNTP
    • Optional: 2xIRIG-B(BNC),1xIRIG-B(TerminalBlock),1xRS-232(DB9),1xRS-232(Terminal) 1xRS-485(Terminal),2x1PPS(Terminal), x1PPM(Terminal)
    • Dual 2 redundant power supplies supported (Optional)
    • Synchronize more than 10 LCD clock via wireless. (Optional)
    • Serial Interface: RS232 and RS485
    • Ethernet Interface: 1 port TCP/IP
    • Protocols :NMEA Output Sequences data format
    • Power: AC110V to 240V or DC12V to 48V, 10%, Less than 5W.
    • Size: standard industry 1U box
