Techniques and methods of geological hazard monitoring based on GNSS

GNSS is currently a major techniques and methods of geological hazard monitoring. The research of GNSS-based geological hazard monitoring system can provide some reference comments to Geological hazard monitoring and prevention. This article summarizes GNSS-based geological hazard monitoring system design by analysis of GNSS system structure and its key technology. Comprehensive analysis indicates that GNSS technology has considerable advantages. It can supply multi-function, multi-demand, multi-level monitoring data to different monitoring objectives for the geological hazards, and it is conducive to real-time monitoring and early warning projects. The current GNSS-based geological hazard monitoring system also need reinforcement of compatible, data integration and usability ,and continue to gradually form advanced, practical and comprehensive real-time monitoring and analysis system based on GNSS.
