Gfuve High Precision 100ns Beidou/GPS Multi-Source SNTP Time Server

Product Description

GFUVE  High Precision 100ns Beidou/GPS Multi-Source SNTP Time Server

GB8002 BeiDou / GPS time server is developed by our company based on GPS timing technology device. It can display and send standard time. The time server uses the PPS and time message of BeiDou Navigation System and GPS (Global Positioning System) satellite to output time synchronization pulse. The device uses SMT surface mount technology for production and high-speed chip for control, with high precision, high stability, strong function, no accumulative error, cost-effective and easy to operate. It is also not limited by geographical and climatic conditions. The device can be widely used in electric power system, network synchronization, communication, traffic management and national defense need timing and punctuality etc. The device has a variety of interfaces. such as RJ45, RS-232, RS-422/RS-485, IRIG-B, TTL Pulse etc. Multi-channel output pulses such as seconds, minutes and hours (free translation), convenient connections and related device, implements unidirectional or bi-directional communication.
