NTS-3000 GNSS
Software Timestamps
NTP, PTP/IEEE1588
NTS-3000 delivers time directly to LAN network using NTP PTPv2 IEEE1588 protocols. It is equipped with 2 Ethernet 10/100Mbps. The GNSS is a standard UTC reference time. Server is equipped with 2 independent GNSS inputs (RJ45: ANT1 & ANT2), therefore it can support redundancy of 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 satellite signals. Extra OCXO* feature is available to provide robust holdover synchronization.
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.
