NTS-3000

Time Server NTP PTP IEEE1588

NTS-3000 delivers time directly to LAN network using  NTP PTPv2 IEEE1588 protocols. It is equipped with 2 independent Ethernet 10/100Mbps. The GNSS is a standard UTC reference time. Server is equipped with 2 independent GNSS receiver inputs (ANT1 & ANT2), therefore it can support independent and redundant satellite receivers too. Each GNSS receiver can be configured to different set of systems (GPS, GLONASS, GALILEO, BEIDOU). Built-in quartz RTC clock guarantees time for limited short period of missing GNSS signals.  Extra OCXO feature is available to provide robust holdover* synchronization.  Server can be synchronized to external atomic clocks using 1PPS-in and rs232 (ToD) interface.

NTS-3000 is STRATUM-1, PTP/IEEE1588 GRANDMASTER supporting software stamps. It offers accuracy of µs on LAN. Server supports leap second, synchronizes UTC time monotonously (jump-free) and can simultaneously serve up to 100,000 NTP clients.

 

Firmware basis on best stable FreeBSD UNIX TCP/IP stack. Unit has natural air cooling system without fans. This fact makes unit long life. Server uptime is counted in years of continuous working 24/7. It is manufactured since 2001 and it is regularly (every year) hardware & software updated to keep state of the art functionality and cyber-security.
