Land Subsidence Monitoring System Based on BeiDou High-Precision Positioning
Land subsidence is a geological disaster caused by natural or human activities. The rate of change in early settlements is often extremely small and presents a challenge to monitoring. This experiment includes BeiDou positioning, multiple antenna, and high-precision baseline solution. It developed the BeiDou deformation monitoring system and used static relative positioning for high-precision land subsidence monitoring. We have adopted integrated hardware design, equipped with a variety of communication modules, satellite receivers, and embedded module in one. In addition, we have developed the corresponding communication protocol for data transmission. Finally, a corresponding monitoring interface software was designed on the client to intuitively reflect the settlement process in a graphical manner.
