This research use aquatic motorcycle in the Bathymetric survey , The system of remote controlled vessel for bathymetric surveys is combined with remote controlled vessel , DGPS and navigation integrated system. The use control navigation speed (3knot, 4knot, 6knot) carries on the experiment in the wharf, NTOU, to investigate the influence factors of this system’s error. The anticipated bathymetric survey standard error can conform to the International Hydrographic Organization (IHO) first-class standards.
Compare by way of the datum and calculate its depth error, carries on the precision analysis. Demonstrated after the analysis that the aquatic motorcycle navigation speed is 3 knot, its standard deviation is less than 0.194m; The navigation speed is 4 knot, its standard deviation is less than 0.301m, conforms to the IHO first-class standards, but works as when the navigation speed is 6 knot, the depth sounding process will produce the miscellaneous news and the system retards, therefore for the maintenance good depth sounding quality, the suggestion should the aquatic motorcycle navigation speed control below 4 knot. The aquatic motorcycle system discussed in this paper is worth to recommend to the practical work of shallow water topographic surveys.
