摘　　要：GPS验潮原理已经发展成熟。按照潮汐测量工作的自动化、高精度的要求,根据海洋浮标的实际工作环境和海洋浮标设计经验,利用嵌入式技术和系统集成技术研制了浮标数据采集器,利用机械设计技术设计了浮标体,并进行了精度验证试验和应用试验,采用GAMIT软件处理浮标数据。试验结果表明,该GPS浮标的瞬时海面高测量精度和潮汐测量精度均满足精度要求,可以应用于海洋潮汐测量工作。The theory of GPS tidal measurement is developed maturely. The buoy is developed according to the actual working environment of the ocean buoy and the tidal measurement 's requirements which include automation and high accuracy. The buoy data collector is developed using the embedded technology and the system integration technology. The buoy body is designed with the mechanical design technology. The experimental and application tests are conducted. The data of the buoy is processed by the software named GAMIT.The test results indicate that the GPS buoy 's accuracy of the real-time sea surface measurement and the tidal measurement satisfies the precision requirement,and then the GPS buoy is capable to be applied to the ocean tide surveys.
