GNSS displacement monitoring station for dam safety

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 the 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.
