Nautronix has commissioned the largest NASDive digital diver communications system for GDA.
The vessel provides support for the Swedish Navy, and is fitted with hyperbaric chambers to facilitate rescue of submariners in the event of an incident.
Following an exercise with the NATO Submarine Rescue system the chamber communication system underwent a full upgrade to NASDive.
Nautronix says the upgrade involved communications a total of 51 individual locations.
NASDive is digitizes all speech at source, eliminating problems associated with signal losses. It also improves unscramble algorithms and helium speech unscrambling. System cabling is also simplified by the use of CAT5e or VDSL. Ethernet hubs are used to marshal the signals, and control of the system is provided via a touch screen display and control unit.
Nautronix says the dive supervisor has full control over all communication locations, and can manage the system by configuring any location into one or a number of groups, each of which the supervisor can select whether he is talking and/or listening to.
Wireless supervisor headsets are used each communication location has local control over microphone and headset volumes, and sideband levels.
Nautronix invested approximately US$1.6 million (£1 million) to refresh its diver communications product line.
