Abstract
Based on the use of Global Navigation Satellite System (GNSS) for meteorological detection in the world, we used the GNSS/MET detection equipment in the meteorological departments of Liaoning Province of China and its data to study and summarize the maintenance methods of GNSS/MET (Global Navigation Satellite System Meteorology) detection equipment and the application of water vapor products in operational systems. The results show that: 1) For GNSS/MET failures, specific inspections and classifications can be performed according to different phenomena; 2) The GNSS water vapor measurement station samples every 30 seconds, forming one set of GNSS data every hour, and can detonate the atmospheric precipitation by solving the original data; 3) Using the “Navigation Satellite Remote Sensing Water Vapor Application Management System”, the GNSS/MET water vapor products can be directly displayed. We can get the conclusion that GNSS/MET has far-reaching significance for studying the law of atmospheric water vapor changes and enhancing the ability to monitor severe weather such as heavy rain and strong convection.

Summary
Global Navigation Satellite System (GNSS) is a satellite navigation system for timing and ranging spatial intersections, including the US’s GPS and China’s Beidou. It can provide continuous, real-time, high-precision 3D position, 3D. Its high-precision, real-time and all-weather characteristics have far-reaching significance for studying the law of atmospheric water vapor changes and enhancing the ability to monitor severe weather such as heavy rain and strong convection. GNSS meteorology is the latest application of GNSS technology in the detection of atmospheric atmosphere by using GNSS theory and technology to remotely measure the Earth’s atmosphere to determine atmospheric temperature and water vapor content, and to monitor climate change. Most of the above studies involve the latest theoretical and technological advances, research on GNSS/MET equipment maintenance, data processing and display applications for local meteorological stations in China is rare, making it difficult for Chinese meteorological departments staff to operate and maintain equipment, and process and use data
