摘要
首先对GPS浮标测波原理进行分析,介绍了GPS接收器测量运动参数的多普勒方法;然后对于在现场测量中可能发生的采样丢失所导致的数据间断进行探讨,并提出了间断接续和冗余采样的解决方法,通过数值模拟实验证明了数据质量控制方法的有效性。
The principle of single GPS based wave buoy is introduced. GPS buoy measures horizontal and vertical wave motion using GPS signals with Doppler frequency shift effect. Meanwhile, data gaps which may occur in heavy sea states are discussed. Furthermore, some solutions about data gaps are proposed. The experimental results of numerical simulation show the validity and feasibility of the data quality control process.
