Dolphin 3040V Specification

The combination of fast update speed and high resolution scanning of the Dolphin Real Time Hybrid Sonar sets unprecedented flexibility for Underwater Vehicle operators.

The compact, rugged underwater unit weighs only 7kg in water allowing the system to be integrated with the smallest of Remote Vehicles. The unit has a standard thirteen pin connector; six pins are used for telemetry and comms data, two for video signal and two for 24v d.c. Power. At the surface the sonar output is routed through a discrete USB interface unit. The USB unit contains the data acquisition hardware to convert the video telemetry uplink into a high speed digital data stream.The system software can be run on virtually any modern "Windows" P.C and is ideally suited to the portability of a notebook P.C provided that the system has at least one USB port. By using optimised display techniques the high speed real time display for the electronically scanning sonar is generated at up to 30 frames per second.

The operator, utilising the huge speed advantage of the electronically scanned system, can pilot the Vehicle using the system software’s real-time “pseudo perspective” mode before switching to the high accuracy mechanically scanned system for close-up inspection of mid water objects and targets in a 360° swath. The Raw data obtained may be logged automatically (at programmed intervals), or on demand, to hard disk for post analysis of survey results. Sonar images may also be incorporated into reports or pasted into other "Windows" applications .

The Dolphin USB Interface unit will operate at full speed when connected to a USB 2.0 port but will also operate at a reduced frame rate when connected to a USB 1.1 port .As the USB Interface is powered from the USB port the system lends itself to being used with a notebook PC.
