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 Chinas wave instrument calibration.
