Overview of Satellite System
The Global Positioning System is a U.S. satellite navigation system sent to the U.S. Naval Observatory to provide time services to users around the world. The U.S. Naval Observatory is formed by multiple cesium atomic clocks. This time source is completely It can meet the accuracy requirements of equipment time synchronization in various industries.
Overview of the Beidou Satellite Navigation System
The Beidou Satellite System developed by my country has three major functions: rapid positioning, two-way data communication, and precision timing. The timing function is the technical basis for positioning and communication functions and is the core of the Beidou System. Foundation. The Beidou timing function is safe, accurate, all-weather and versatile, and is suitable for all aspects of my country's timing needs.
Time calibration device
It is a high-performance redundant Beidou synchronous clock carefully designed and independently developed by Jinan Weishang Electronics Co., Ltd. It adopts high-precision timing type, Beidou module and precision time synchronization technology. It has realized multiple sources of time base (, Beidou, atomic clock, constant temperature crystal oscillator, B time base), output multiple formats (serial port, pulse, B code,, / network timing, etc.), and can satisfy multiple devices (system signal output can be expanded arbitrarily, It can meet the requirements of time signal requirements of any scale and mode, ensuring high accuracy, high stability, high security and high reliability of time synchronization signals. The device has the characteristics of high timing accuracy, stable operation, small transmission error, easy installation, economical and practical, simple operation, fully automatic intelligent operation, maintenance-free, etc. It is suitable for unattended operation and has been widely used in metallurgy, communications, electric power, etc. School-time services in finance, radio and television, security, transportation, water conservancy, national defense, petrochemicals, medical care, government agencies, education and other fields.
