To prevent forgetting to report entry by VHF radio telephone, etc. to local maritime traffic centers, which is required when a ship attempts to enter a designated sea area.SOLUTION: An automatic position reporting device includes: a position acquisition unit that acquires a position of a ship that passes through a position reporting line defined on a nautical chart; a position determination unit that determines whether the position has reached the position reporting line; a call start determination unit that determines whether or not a call is possible when the position reporting line is reached; and a synthesized voice transmitter that transmits synthesized voice when the call is possible.SELECTED DRAWING: Figure 1
【課題】船舶が指定海域に入域しようとする際に必要となる、各地の海上交通センターに対するVHF無線電話などによる入域通報の、通報忘れを未然に防ぐこと。【解決手段】自動位置通報装置は、海図上に定められた位置通報ラインを通過する船舶において、船舶の位置を取得する位置取得部と、前記位置が位置通報ラインに到達したかどうかを判定する位置判定部と、前記位置通報ラインに到達した場合に通話が可能であるかどうかを判定する通話開始判定部と、前記通話が可能である場合に合成音声を送信する合成音声送信部と、から成る。【選択図】図1
