GPS wave buoy designed by National Ocean Technology Center just requires a GPS receiver without any extra sensors

it has characteristics of low power consumption

small size

easy to deploy

high measurement precision and suitable for wave measurement in large-scale and meticulous ways. In order to solve problem of deep and remote sea GPS wave buoy data transmission

by comparing characteristics of three kinds of satellites system of Argos

Iridium and Bei Dou

this device gives priority to adopt Bei Dou satellites system to transmit data. System constitution

hardware circuit design

measurement datas and data transmission flow are separately described in detail. Through laboratory and field test

specifically when GPS wave buoy is under the situation of harsh environment

such as typhoon

it is proved that the Bei Dou satellites system can be used in deep and remote sea data transmission and its reliability is verifies.
