The measurement method using sound waves (e.g., SONAR) is general method of location measuring in the underwater. However, the accuracy of this method is not sufficient to measure the location of seabed mining vehicle. In addition, the optical positioning method can’t measure accurate position of seabed mining vehicle because the surroundings of the seabed mining vehicle are muddy during mining of resources. Thus, we propose a new positioning system that avoid muddy area. In this system, the measuring device is floated by float right above the seabed mining vehicle, thereby enabling the measurement avoiding the muddy area. The measuring device is installed in the tracker having a thruster. And the tracker keeps the measurement accuracy by following the seabed mining vehicle. In this paper, we describe details of new positioning system and tracker.
