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 “long baseline system” (LBL). The system functions with several transmitters/receivers 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 a precision of 1 meter at all times. 

By importing a sea chart into the system, the submarine´s geographical position can be displayed on a sea chart.

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.
