| Abstract: | This paper analyzed the existing methods of wave measurement, and described the advantages of GPS to measure wave. The equations of absolute velocity estimation were discussed, focused on two methods with Doppler shift. The error sources and their effect on velocity estimation were analyzed. Then, some tests were carried on to simulate dynamic velocity determination using static data. With the use of high-frequency carrier-phase derived Doppler observations, the velocity has been estimated to the precision of 1cm / s or so, even can be mm / s level. And with the receiver generated Doppler measurements, the precision was 3~15cm/s. |
