| 摘 要： | 采用高精度载波相位差分（RTK）技术,通过融合解析多星（中国北斗、美国GPS和俄罗斯GLONASS）定位信号,实现全天候、高精度和全参数（波高、波周期和波向）现场实时校准技术。通过反复多次测试,单星、双星和多星系统测量精度分别可达到0.05 m、0.03 m和0.02 m;波向最大示值误差为3.52°。较大幅度提升了我国波浪仪器校准技术水平。

| Abstract: | The high-precision technology of real-time kinematic (RTK) is studied, and through the multiple analytical satellite positioning signals (China Beidou, American GPS and Russian GLONASS) ,to achieve all-weather, high precision and full parameters (wave height, wave period and wave direction) real-time calibration technology.By repeated tests, the wave height measurement accuracy, single and binary star can reach 0.05m, multi satellite system can reach 0.02m, and the maximum error of the wave direction is 3.52°.Therefore, the fusion wave measurement by Beidou satellite can greatly enhance the technological level of China`s wave instrument calibration. |
