The GPS NTP Time Server is designed for complex multi-network environments. Equipped with four independent LAN ports, it supports synchronization across four separate network segments, making it ideal for physically isolated networks. As a Stratum 1 time source, it obtains high-precision timing from GPS and BeiDou satellites, ensuring absolute synchronization with UTC.

The GPS Time Server Description
The GPS Time Server NTP400 leverages advanced multi-constellation satellite signals (GPS & BDS) to provide an ultra-reliable time reference. By synchronizing with Coordinated Universal Time (UTC), it achieves a frequency stability comparable to cesium atomic clocks, ensuring an incredible accuracy that deviates by only one second every 300,000 years. This high-precision source eliminates local clock drift, providing your network with a rock-solid temporal foundation. Equipped with a professional-grade timing receiver, it guarantees rapid signal acquisition and a stable, continuous lock.
The GPS Time Server Features
✔ Secure & Flexible Management: Intuitive Web-based UI with a high-security cipher suite (HTTP/HTTPS), plus CLI and physical keyboard support for rapid deployment.
✔ Ultimate UTC Precision: Delivers exceptional time accuracy synchronized directly with global satellite standards.
✔ Universal Protocol Support: Fully compliant with NTP (RFC1119/1305) and SNTP (RFC1769/2030) for seamless integration.
✔ Robust Network Security: Features SNMP management, syslog logging, and built-in iptables firewall protection.
✔ Reliable & Traceable: Includes trace logs and a secondary development interface; boasting an MTBF of 90,000 hours for long-term industrial stability.
