L1000-ENC01「single-port」北斗GPS web实时管理 可拓展晶振、铷原子钟

The L1000-ENC01 NTP Network Time Server provides accurate, reliable, and secure high-precision satellite time references for network devices, terminals, and servers within firewalls. It can support time synchronization for tens of thousands of clients that are compatible with the standard Network Time Protocol (NTP, including V1/2/3/4) and Simple Network Time Protocol (SNTP). NTP network time servers have been widely applied in various fields such as finance, transportation, securities, power, mobile communications, petroleum, industry, e-commerce, industrial automation, cloud computing, security, smart cities, the Internet of Things (IoT), energy, and national defense.

The device adopts a redundant architecture design. It internally constructs a disciplining system composed of separate CPU and FPGA circuits. The disciplining system receives ephemeris data from satellites within the GPS and Beidou systems, as well as atomic clock frequency standards. Through delay compensation, filtering, and PID algorithms, it achieves local clock synchronization and high-precision timekeeping functions. With professional digital hardware design and an efficient Linux operating system, it offers multiple reliable clock signal output functions.

The L1000-ENC01 product is designed to support all versions of the NTP protocol, symmetric MD5 secure encryption protocols, and asymmetric RSA certificate encryption protocols. The time synchronization accuracy for clients is better than 2 milliseconds. Additionally, it supports functions such as serial port NMEA0183 output, 1PPS (One Pulse Per Second), 10MHz (RB/OCXO) signal output, local and remote log recording, green terminal dry contact alarms, USB port upgrades, and network data uploading and downloading. When used in conjunction with a unified GNM monitoring system across the entire network, it enables real-time monitoring of the server's operational status, client deviation status, client synchronization status, and alarm functions.

This device is suitable for long-term connection to the GPS and Beidou systems and requires real-time connection to GPS and Beidou satellite antennas. In the event of GPS/Beidou system failures or antenna failures, it will no longer provide network time-keeping services. Our company offers a refund guarantee, a three-year warranty, and lifetime free technical support.
