Abstract
The tidal effect is a main error source in GNSS positioning. It is analyzed in detail by tide computation and practical data processing in this paper. The results show that the effect of the tide on static and kinematic positioning is related to the observation time, the station location and the length of baseline, respectively. The tidal effect on coastal stations is greater than that on inland stations. The difference of the tidal effect is great even for nearby coastal stations. However, the effect shows zonal distribution for inland stations. Therefore, it has to be taken into account even for a relative small coastal GNSS network. Static GNSS data kinematic processing experiment and airborne kinematic GNSS data processing experiment are done in this paper, and the results show that the tidal effect can be detected by GNSS surveying.
