GPS NTP Network Time Server

GlobalTime ® NTP Network Time Server supplies accurate time for all computers and time keeping devices on the network. By placing a time server on the local network, (S)NTP time packets are provided without requiring systems to go to the Internet to get a Stratum 1 time synchronization. The system uses an active GPS antenna to maintain the current time as broadcast by GPS satellites.

Features

• Stratum 1 operation via GPS/BeiDou satellites, can also be set as a stratum 2 time server to synchronize with host time server

• One/two/four standard GbE ports, all with patented NTP hardware timestamping. The LAN port ETH0 is the management port and cascade port. All ports support SSH/ SNMP/HTTP/HTTPS/NTP.

Web-based management with high security cipher suite, supports HTTP/HTTPS. Supports CLI configuration. Keyboard can be used for easy and fast configuration.

• Exceptional time accuracy to UTC

• Extended environmental specifications

• NTP Server Performance: 20000 NTP requests per second while maintaining accuracy associated with reference time source

Uses RFC1119/1305 NTP (Network Time Protocol)

Supports RFC1769/2030 SNTP (Simple Network Time Protocol)

Supports SNMP, with a serial port for to log in; supports syslog, with iptables security protection.

Supports tracelog. With a second development interface.

• IPv6/IPv4 on all ports. Supports multiple ports BONDING and multiple routes.

• GLONASS/Galileo option

• MTBF: 90000 Hours

Optional TOD/1PPS/10MHz/PTP/IRIG-B output

Optional Rubidium atomic clock or OCXO oscillator upgrade for extended holdover

Applications

• Synchronizes hundreds of thousands of NTP clients

• Security-hardened for peace-of-mind time service operations

• Multiple GbE NTP ports for easy network configuration and adaptation

• Best-in-class time accuracy for improved log file timestamp precision and usability

Very reliable and easy-to-use network time appliance for modern networks and business operations
