Abstract:	Many ocean-based GNSS applications, such as meteorology, exploration, offshore drilling, geodesy, and tsunami warning systems, require precise cm–level positioning. Differential baselines relative to fixed landbased stations are often not feasible for receivers on a ship or buoy in the open ocean, because of the large distances that are involved. Such receivers are generally moving and are best positioned in kinematic precise point positioning (PPP) mode. We applied PPP positioning to receivers on a ship in the Indian Ocean and we tested PPP with ambiguity resolution “PPP-RTK” on a tsunami buoy off the coast of Japan. This paper discusses the quality of ocean based GNSS results
