摘要
全球定位系统(GPS)浮标是高度计海面高度定标的重要仪器。本文介绍了GPS浮标的组成和工作原理,分别对GPS浮标的外型设计、舱体设计、密封性设计、供电设计做了详细介绍,最后利用数值模拟的方式,对设计的GPS浮标在3级海况下的摇摆和升沉响应进行模拟试验。结果表明自主设计的GPS浮标能够满足海上高度计海面高度定标的需求。
GPS buoy is an important instrument for the calibration of altimeter sea surface height. This paper introduced the composition and operating principle of GPS buoy,and described in detail the design of shape,cabin,leak-proofness and current supply. Finally,using the numerical simulation,the waver and undulation of GPS buoy were experimented in the 3rd class sea state. The result showed that the GPS buoy designed can meet the challenge of the calibration of altimeter sea surface height on the sea experiment condition.
