This research studies the methodology of using GNSS for tide estimation. It mainly investigates suitable filtering methods to extract tide signal from temporal changes in GNSS estimated height of the sea surface. These GNSS heights were estimated in nearshore and offshore environments and factors affecting tide estimation in both environments were analysed. The results suggest that GNSS estimated tides is suitable for hydrographic surveying, marine geodesy and in real time for natural hazard warning systems.
