Localization of computer GPS timing

computerGPSTiming Overview:

computerGPSLocalization of timing (Beidou timing products),NTPNetwork time server,GPSThe timing device is an intelligent typeGPSThe Beidou reference clock source outputs a pulse signal as its signal output（1PPS/M/H，TTLEmpty contact, differential, active, optical), time message（RS232TheRS422/485(Light)IRIG-BSignal（DCTheAC(Light)DCF77signalNTP/SNTPProtocol network signalPTP（IEEE1588）Protocol signals can meet the timing interface requirements of different devices and are widely used in various fields that require stable time base and strict time base synchronization,Such as communication, petrochemicals, broadcasting and television, transportation, electricity, healthcare, national defense, finance, etc.

computerGPSLocalization of timing and productsGPSThe signal is used as a time reference, and the Beidou satellite can also be selectedIRIG-BCodeOCXORubidium atomic clockCDMASignal and other time sources, with timing accuracy of up to30nSThe device adopts distributed structure, closed-loop design, power-off protection, fault self diagnosis, fault isolation, software and hardware redundancy, resistance to electrical electromagnetic interference, protective grounding and other technical measures.

computerGPSCharacteristics of timing

1Adopting separate screen grouping, flexible expansion, and easy management.

2、 Multiple time sources to choose from, in addition to usingGPSIn addition to the system, China's Beidou system can also be used for higher reliability.

3Adopting a transparent design for on duty personnel.

4The main clock and expansion clock adopt redundant configuration and automatically switch without disturbance.

5High timing accuracy, with precision reaching30nS.

6The main clock and expansion clock have high-precision time self holding units inside, with an accuracy of7×10^-9.

7Multiple timing protocols can be specified by user requirements.

8There are multiple timing methods available, which can be flexibly configured and support hard timing（PPSThePPMThePPH）Software timing (serial port message), encoding timing（IRIG-BTheDCF77）And the internetNTPAt the right time.
