GS3114 GNSS Multi-Frequency Timing and Positioning Equipment - PNT Server
Products Introduction
The GS3114 high-precision Position Navigation and Timing PNT device is a network time server that provides BeiDou/GPS positioning, timing, network time synchronization, and holdover functionality.
It integrates a multi-frequency timing and positioning receiver that supports multiple GNSS constellations, combining both the BeiDou and GPS satellite navigation systems. Both systems operate in passive timing and positioning mode. The device is capable of receiving full GPS and BeiDou-2 satellite signals, and the two systems can operate independently to deliver precise 1PPS signals, accurate time information, and positioning data. Time information is also distributed via the NTP protocol to client devices which requiring time synchronization.
In addition, the device features a built-in high-stability clock source. When the external reference signal is lost, it automatically switches to holdover mode. Thanks to advanced holdover algorithms, the device maintains high timing accuracy for an extended period after the external reference is lost.
Application areas
Time synchronization for civil air defense systems, financial/banking systems, transportation systems, power systems, broadcasting systems, railway systems, etc.;
Time synchronization for aviation and aerospace systems;
Time synchronization for base stations, control stations, monitoring stations, etc.
Features
-
It features 4-channel NTP time sync service, supports 4 different network segments, and allows independent configuration of IP addresses and network segments;
-
It has a built-in high-precision multi frequency GNSS receiver, which can receive high-precision Beidou-2/GPS satellite time information and control the internal high-stability clock source;
-
Outputs high-precision time information, geographic location information, second signal, and NTP time synchronization information;
-
It has a display function, showing time information (year, month, day, hour, minute, second) and geographical location information (latitude, longitude, altitude);
-
It can output various signals, including 2 local 1PPS second signals (BNC), 4 RS422 second signals, 4 RS422 serial port time information, 4 RS232 serial port time information, 4 network port geographical location information as well as 4 NTP time sync information to serve as a network time synchronization server;
-
It has a timekeeping function. When the external reference is invalid, the device automatically switches to holdover mode and continues to output high-precision time information and second signals;
-
External references can be switched automatically or manually via a rotary knob on the back. The default mode upon startup is GPS.
