    For the routine Global Navigation Satellite System – Acoustic ranging combination (GNSS-A) seafloor positioning procedure in the Hydrographic and Oceanographic Department of the Japan Coast Guard, baseline analysis is used to determine the precise ship track. However, especially in cases such as emergency observations after a large earthquake, there may be a possibility of delay or failure to access the terrestrial reference GNSS data. In contrast to baseline analysis, kinematic precise point positioning (PPP) has advantages when providing rapid solutions of GNSS-A seafloor positioning. Prompt reporting of GNSS-A results will also be needed in the future for applications such as data assimilation in a plate boundary state prediction model. In this paper, we evaluated the dependency of GNSS analysis strategies on the GNSS-A solutions and validated their equivalency within the GNSS-A positioning precision.
