Relationship of the uncertainty between the positioning and the sound speed in GNSS-A seafloor positioning.
We investigated the influence of the variation in the undersea sound speed on the solution of GNSS - Acoustic seafloor positioning. Our results indicated that the horizontal components of the seafloor position are almost independent of the sound speed. On the other hand, the vertical component has a region that depends on the sound speed. The width of this region can be interpreted as the resolution of the vertical positioning and depends on the analysis method and the quality of the data. Therefore, the dependency of the positioning on the sound speed can be a quality indicator for the analysis and data.
