High precision monitoring system by satellite signal reflector

In conventional geological disaster monitoring, the contradiction between the cost and precision has always been a concern. In this paper, we propose a remote monitoring system by a reflector. Concretely, a reflector is designed to transmit the satellite signals received from the monitored site to the stationary base station through the wireless transmission. Then uses signals from different antennas to establish a double-difference model. So as to realize low-cost remote monitoring. The experimental results show that when the reflector signal transmission distance is 0.2km, the monitoring accuracy of the system is within 3cm.
