Acoustic Doppler Current Profiler

In many cases, current meters that are located on the sea floor and use acoustic methods (Acoustic Doppler Current Profiler, ADCP) present an alternative to measuring buoys in water of depth up to 40 m. They do not require a mooring that is susceptible to wear and tear, and they are less imperiled by ship traffic. The data transmission to the shore, however, provides more technical difficulties.

The wave measured automatically by the acoustic Doppler current Profiler ( AWAC wave Dragon) (Liu, J Lu, Z 2009). Measured data contains pressure, unit velocity along three oblique beams and wave height along a vertical beam (AST), the sampling frequency is 2 Hz, and each pulse emission sampling number is 2048, wave record every hour, each time record 18 minutes (no less than 100 waves). 

Finally, the rear section contains essential hardware components control actuation, propulsion. This section also houses scientific sensors (e.g., digital camera, upward looking acoustic Doppler current profiler (ADCP), 200kHz multi-beam receiver). A rear mounted rudder and stem plane are used to control the vehicles yaw, pitch and depth.
