Navigation/GIS

Submarine LULA is operated in conjunction with a precise underwater navigation system. This is particularly important when doing archaeological work, so as to be able to define the exact geographical position of a wreck or archaeological site and to refind the location in follow-up dives. 

The system used is a “ultrashort baseline system” (USBL). The system functions with a transmitter/receiver which communicate via high frequency acoustic signals and calculate the submarine´s position underwater.

The transmitter/receiver mounted on the submarine is connected to a notebook computer in the interior of the cabin and shows the submersible´s position and depth with high precision at all times. 

The distance sailed underwater is logged automatically. Later on, this data, can be superimposed on a sea chart to make the actual underwater route visible.
