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 SISDATA 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 SISDATA 1N-NTP is quite cost effective and high quality, its highest record of MTBF is 12 years.   

 

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(Terminal Block),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
