PROBLEM TO BE SOLVED: To provide an underwater sound positioning system which uses an acoustic signal to observe the position of an autonomous underwater robot or a mobile body moving in an underwater space or to observe a structure or a crustal alteration, for example, in a shallow sea under a severe environment.SOLUTION: The underwater sound positioning system can take a correct image of an object by light of an optical trigger signal without using a special light depending on an underwater part, can obtain a large amount of data, for example, from the underwater part more quickly and more accurately, and can stably increase the accuracy and density of acquiring positional data on the underwater part.SELECTED DRAWING: Figure 1

    【課題】本発明は、苛酷な環境下において、水中空間を移動する自律式水中ロボットまたは移動体の位置、あるいは浅海における構造物または浅海の地殻変動等を音響信号によって観測する水中音響測位システムに関するものである。【解決手段】本発明の水中音響測位システムは、水中部に依存する特別な照明を用いることなく、光トリガー信号の光によって、対象物を正確に撮影するとともに、前記水中部からの多くのデータ等を短時間で、より正確に得ることができ、前記水中部に対する位置データの取得精度、密度を安定的に向上させることができるものである。【選択図】図1
