GS500 GPS Master Slave Clock System
Products Introduction
The GS500 time and frequency standardization system is a fiber ring network timing system meticulously designed and developed for shipboard environments.
This system comprises two master clocks and two salve clocks. The master units can receive multi GNSS (GPS GLONASS Galileo BeiDou) satellite navigation information, B-code information, and shortwave time synchronization signals to perform time and frequency calibration functions. The master units also have power-off timekeeping capabilities and certain time and frequency output interfaces.
The slave units synchronize with the master units via fiber optic cables to complete their own time synchronization and frequency calibration, outputting their own high-precision time and frequency signals through the time and frequency output interfaces.
The two master units and two slave units can form a system ring network, improving the stability and reliability of the system's time and frequency signal output.
Application areas
Shipboard time frequency unified system;
Time unification systems for various center stations, monitoring stations, etc. .
Features
- Equipped with fiber optic loop time and frequency synchronization and communication functions, the system serves as a fiber optic dual backup time system;
- The system has dual master and dual slave backup capabilities;
- High-precision time and frequency transmission and recovery capabilities via optical fiber;
- Equipped with dual CAN communication management buses;
- It integrates a multi-reference GPS GLONASS Galileo BeiDou receiver and supports long-wave, short-wave, and other signals. Reference sources can be switched and combined freely as needed.
- It has a high-precision timekeeping function;
- It provides multiple output signals (10MHz, 1PPS+TOD, B-code) along with NTP and PTP time synchronization, and can function as a GPS network time server.
- It has comprehensive network management functions.
