GS3100 GPS NTP Time Server
Products Introduction
The GS3100 GPS NTP Network Time Server is a high-precision time server device.
It features a built-in high-precision GPS/BeiDou dual-mode receiver, which locks onto satellite signals to discipline the internal clock source (crystal oscillator), enabling the output of high-precision time information and frequency reference signals. The device can provide accurate time synchronization services to various network devices via the NTP protocol, offering multiple time synchronization methods for ease of use.
In addition, the device has a holdover function with high accuracy, maintaining a certain level of precision even for an extended period after the external reference is lost. The device provides the following outputs: one channel of the receiver's raw 1PPS signal, one channel of the receiver's raw serial time information, two channels of NTP time synchronization information, one channel of 1PPS signal, and one channel of serial time output.
Application areas
Time sync 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
-
The device offers versatile functions, rich output types, and flexible configuration, with output optional B-code, PTP, 1PPS+TOD, and more to meet different functional requirements;
-
The device features a built-in GPS/BeiDou dual-mode receiver with selectable reference sources (GPS only, BeiDou only, or hybrid mode). Optionally, it can be equipped with a multi-constellation GNSS receiver supporting GPS, GLONASS, Galileo, BeiDou, transforming it into a multi-frequency GNSS NTP server;
-
It features a built-in high-stability constant-temperature crystal oscillator, ensuring high timekeeping accuracy. Users can also select a rubidium clock according to their actual needs;
-
Featuring NTP output with support for NTP/SNTP V1.0, V2.0, V3.0, and V4.0, the device utilizes 10/100/1000M Ethernet to serve as a fully capable NTP time clock;
-
Supports devices operating systems such as Windows, Linux, and Unix;
-
Supports user list functionality;
-
Built-in RTC, retains data for a certain period of time even after power failure;
-
It has remote monitoring capabilities and can report equipment operating status information, facilitating remote monitoring and control;
-
The working status of the equipment and each module can be queried, and it has a health check function;
-
The network segment and IP address can be set independently , and the front panel is equipped with an LCD screen for separate settings;
The modular/card-based design allows the output network interface to be expanded into multiple network ports.
