NTP Time Server, GPS/GLONASS/Galileo/Beidou OCXO, 1PPS, IRIG-B, TOD, 1x 10/100BaseT

Tavallisten tietokoneiden tai tietoliikennelaitteiden
sisäiset kellot ovat epätarkkoja, kuukaudessa kello voi
heittää useita minuutteja. Nykyiset IT-laitteet osaavat
internet-yhteyden avulla päivittää aikansa internetin NTP-
aikapalvelimilta. On myös suljettuja käyttöympäristöjä,
joista liikennöinti internetiin on haluttu estää, kuten
turvalliset tuotekehitys-, testaus-, laboratorio-,
tuotannonohjaus-, sähköverkko-, konesali-, kameravalvonta-
tai kulunvalvontaympäristöt. Tällaisessa ympäristössä
tarvitaan erillinen NTP aikapalvelin, joka palvelee
lähiverkon IT-laitteita tarkan ajan säilyttämiseksi
esim. tallenteissa ja lokitiedoissa.

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.

Features:
• Support for GPS, Beidou, GLONASS, GALILEO, QZSS
• 1PPS synchronization accuracy can reach 15ns
• When the satellite reference source is lost, it has a
punctuality function
• With the function of antenna open circuit and short
circuit detection
• NTP time synchronization accuracy 0.5-2ms
• NTP v2 (RFC 1119), v3 (RFC 1305) v4 (RFC 5905)

• Support MD5 information verification
• Support SERVER and BROADCAST working mode
• Support DC IRIG-B (without AC IRIG-B)
• Rich interfaces
• Software is provided free of charge. Simple interface and
easy to use
• Status view: Host computer software can query and control
the device through the monitoring serial port or network TCP
protocol, and the device information status is clear at a
glance
