GPSDO GPS Disciplined Oscillator GPS Disciplined Clock NTP Time Server without IRIG-B AC Code

GPSDO GPS Disciplined Oscillator GPS Disciplined Clock NTP Time Server without IRIG-B AC Code

Description:
Satellite time frequency standard source/NTP network time server can receive satellite timing signals for GPS, Beidou, GLONASS, GALILEO, QZSS to tame the internal OCXO (high stability constant temperature crystal oscillator), can provide UTC standard time and self-perfect monitoring, Highly stable 1PPS, IRIG-B, TOD, 10MHz, NTP and other primary clock synchronization signals. Using closed-loop control and punctuality technology, the system has self-learning function to obtain the aging drift of high-stability constant-temperature crystal oscillator, even if the satellite signal is interrupted or interference failure occurs, it can still output accurate time synchronization signals within a certain time to achieve high Punctuality of precision. This series of products has been tested by a large number of practical applications in the market, and is stable and reliable.
