基于GNSS的浮标测流方法研究OA
Study on a GNSS-Based Buoy Method for Flow Measurement
基于 GNSS 测速原理,提出一种改进的 GNSS 浮标测流方法.实验分析表明,该方法不需要高精度 GNSS 设备,即可满足浮标法测流的精度.该方法依靠单机 GNSS 即可实现水体表面流速测量,能够大幅降低GNSS 的设备成本,可为水文应急监测提供有效的手段.
Based on the GNSS velocity-measurement principle,this paper proposes an improved GNSS buoy method for flow measurement.Experimental analysis shows that this method can satisfy the accuracy requirements of buoy-based flow measurement without the need for high-precision GNSS equipment.Relying only on a single GNSS unit,the method can measure surface flow velocity of water bodies,greatly reduce the equipment cost of GNSS,and provide an effective means for hydrological emergency monitoring.
