Abstract :
HF radar is a remote sensing technique for measuring surface currents and ocean wave directional spectra. This paper describes the extension of a land based system to enable surface current measurements from a slowly sailing ship. To compensate for the ship´s motion, the Global Positioning System (GPS) has been used. Due to additional error sources compared to the land based system, the accuracy of measured currents is slightly reduced from 2 to 5 cm/s to 3 to 10 cm/s
