See Bed Bathymetry Sonar Specification

The Transmit and Receive Transducer arrays are arranged in an inverted “T” configuration. The transmitter and receive electronics are mounted within the arrays with the digital sonar data being transferred to the control / display computer over a fiber optic link.

The sonar scans a horizontal sector of 90 degrees to a 1.5 degree resolution and a vertical sector of 20 degrees to a 1 degree resolution simultaneously for every “ping” of the transmitter.

Operating at up to 30 swaths per second data is collected and displayed in real time the data being corrected with the addition of an external motion reference unit and GPS. The sonar housing is manufactured of aluminium and hard anodised to allow the unit to be operated to 500m depth. An optional 3000m depth unit is available manufactured in stainless steel.

Data collected by the sonar head is transferred to the operating PC, running under windows, over a video link and connected to the computer via the USB interface unit supplied. The data can also be output to most software packages used to display bathymetry data. Command and control data to the sonar head can be either RS232 or RS485 at 19200 baud.

The user friendly PC software running under windows provides all the controls for the sonar on screen and displays the sonar image plus history of the selected white line trace.
