Tracking Subs During Dives?

During mission or test dives, our surface support crew must have the submersibles' locations at all times. To accomplish this task, Global Sub Dive's team utilizes a Tracklink 1500 USBL (ultra-short baseline) acoustics tracking system. Our Tracklink systems has a fully integrated high speed acoustic communication capability. It utilizes modern digital signal processing techniques and possesses a state of the art digital signal processor (DSP) that helps track the submersible from launching to retrieval.
