GS5500 Time and Frequency Reference Server - NTP PTP Time Server
Products Introduction
The GS5500 time and frequency reference device is a standard time and frequency source designed to provide high-precision reference signals. It integrates a high-precision BeiDou-2/GPS timing receiver, which disciplines and phase-locks the internal high-performance clock source (crystal oscillator or rubidium oscillator, user-selectable) to satellite signals, ensuring that the output timing signals are synchronized to the satellite reference and that the frequency signals are traceable to the satellite source. When the external reference is lost, the device automatically switches to high-precision holdover mode.
The device also offers optional multiple time reference inputs, including B-code and 1PPS+TOD, for time and frequency synchronization. A wide selection of output signals is available, with optional configurations including 10MHz, 10.23MHz, 100MHz, 1PPS+TOD, B(DC), E1, NTP, and PTP. Thanks to its highly integrated and modular design, the GS5500 provides maximum flexibility to meet diverse user requirements for time and frequency references.
Application areas
Time synchronization for civil defense systems, banking/financial systems, transportation systems, power systems, broadcasting systems, railway systems, etc.;
Time synchronization for aviation and aerospace systems;
Time synchronization of base stations, control stations, monitoring stations, etc.
Features
-
It has a built-in high-precision BeiDou/GPS dual-mode receiver and supports multiple timing modes such as single GPS, single BeiDou, and BeiDou + GPS autonomous fusion;
-
The internal clock source is user-selectable, offering a choice between a 10 MHz GPS disciplined oscillator and a rubidium clock;
-
An external reference signal is optional, and the optional signal types include external 10MHz input, external 1PPS input, external TOD input, external B (DC) code input, etc. Users can choose the appropriate one according to their needs;
-
Features two operating modes: discipline and holdover. In discipline mode, the device locks to the external reference and continuously adjusts the internal clock source to maintain synchronization. In holdover mode, the internal clock operates independently of the external reference, leveraging its own stability and intelligent holdover algorithms to deliver high-precision timekeeping;
-
It has two time synchronization modes: manual and automatic. In manual mode, users can set any time to realize the functions of clock setting and time zone setting;
-
It features an LCD display and button settings, capable of displaying time information such as year, month, day, hour, minute, and second, current reference, working mode, and device working status information. With the buttons, it can realize functions such as reference source
-
switching, working mode setting, time synchronization method setting, and IP setting;
-
Common signal outputs include: 10MHz frequency standard signal, 1PPS second signal, and NTP PTP time synchronization signal;
-
Optional output signals include: TOD signal, 10.23MHz frequency standard, 100MHz frequency standard, etc.;
-
It can also function as an IRIG B time code generator, outputting the B(DC) code;
-
Optional features include: E1 synchronization and PTP frequency synchronization;
-
It has remote monitoring capabilities.
