1Hz 24 Hours GNSS Bridge Dam Deformation Monitoring System

All-weather 24 hours per day Real-time Monitoring
Different from traditional monitoring methods,gMOS is unaffected by the climate. The system provides 24 hours per day real-time three dimensional high-precise monitoring of targets. By directly processing the raw data from both base station and monitoring station at the control center,gMOS improves the performance of real-time and synchronous monitoring obviously.

High Precision
Using the global advanced high-precise GNSS real-time dynamic positioning technology and related algorithms, gMOS overcomes the limitations of a variety of conventional GNSS applications such as electromagnetic interference, block, multi-path, time synchronization, etc. The system can help engineering researchers and monitoring managers processing data efficiently, and provide deformation information at millimeter level.

Intelligent Analysis and Beforehand Alerts
gMOS provides different analysis models for different applications, which can not only reflect real-time condition of monitoring object exactly, but also analyze related data intelligently. The system can help users carry out preliminary risk assessment, and publish alerts timely in various ways and in different grades. With the solid technical support and reliable information gathered by gMOS, the monitoring managers and decision-makers can get to know the safety condition of the targets, and then choose proper processing procedure accordingly, so to keep the deformation under the control.

Distributed Architecture
gMOS adopts client/server distributed architecture. After Stone RT server is set up, users can install gMOS client on terminal (equipment supporting network communication, such as PC, mobile phone, etc.) to connect remote server, and to know the latest real time deformation information.

Support Various Receivers
gMOS delivers affordable solution on the condition of ensuring the efficient monitoring and the accurate performance. Giving full consideration to the actual conditions and the budge of the project,gMOS supports a variety of mainstream single or dual frequency GPS receivers to meet customers’ requirements.
