GNSS displacement monitoring system - a deep and loving GNSS slope monitoring system that never misses its promise in 2024

WX-WY1- Geological hazard monitoring refers to the continuous and systematic observation and analysis of the geological environment to identify and predict potential geological hazards, such as landslides, mudslides, earthquakes, etc. The importance of this work lies in its ability to provide early warning before disasters occur, winning valuable time for disaster response and disaster reduction and relief work.

1、 Product Introduction

The GNSS monitoring system is based on a satellite positioning system with known spatial positions and adopts the basic principle of space rendezvous to achieve absolute positioning of ground user terminal devices. The receiver terminal deployed on site remotely and wirelessly transmits observation data to the monitoring center (usually cloud based receiving and storage) according to the established collection and transmission frequency. The monitoring center analyzes and processes the observation data in real time for use by relevant technical and management departments.

From the perspective of data flow and functional division, the entire monitoring system can be divided into three main parts: spatial part, ground reference station part, and monitoring terminal part.
