RESON has launched a new version of the well-known SeaBat 7125 multibeam sonar system designed for easy installation on small surface vessels and with the same exceptional performance.
One Unit For Sonar Interface and Processing
The most notable change is a new transceiver that combines the function of sonar processor and interface unit, thus removing the need to install the LCU bottle used in the deep-rated SeaBat 7125 systems. Cable length of 25m (standard) or 50m (optional) between the transceiver and transducer arrays allows simple installations on most small vessels.
Increasing Survey Productivity Through Enhanced Efficiency
All performance and acoustic parameters are identical to the other members of the SeaBat 7125 family. Through a number of features data collection and processing times are reduced and surveying productivity is maximised using SeaBat 7125-Surface from surface vessels:
- Single or dual-frequency operations (200kHz and/or 400kHz) to ensure high flexibility.
- A ping rate of 50Hz (range dependent) with 256 equiangle or 512 equidistant beams per swath ensures exceptionally high data density.
- Advanced signal processing and bottom detect routines deliver second-to-none data quality.
- SeaBat 7125-Surface is fully backwards compatible with LCU and other SeaBat 7K transceiver systems.
New Features in SeaBat 7125-Surface
SeaBat 7125-Surface also offers a number of new and unique features. The new transceiver provides an integrated multiport serial card and is available with PDS2000 pre-installed for data acquisition and display, as well as data processing on the same hardware platform. Four video outputs allow multiple user and helm displays to be run.
Variable swath coverage of up to 128° to a maximum range of 500m offers the preferred combination of swath and resolution. A real-time uncertainity output from the SeaBat 7125 may be used in PDS2000, along with information from other sensors to calculate a total propagated error (TPE). Soundings may be filtered by setting the relevant IHO order or defining custom vertical error limit. Other new features include roll stabilisation, XYZ offsets, quality filter and advanced diagnostics.
SeaBat 7125-Surface was introduced for the first time during the Shallow Survey 2008 conference and exhibition in Portsmouth, NH, US. Live on-water demonstrations of the system were conducted throughout the Shallow Survey.
With the release of the SeaBat 7125-Surface dual-frequency multibeam echosounder, RESON has again demonstrated continual developments and improvements in the SeaBat range of sonar systems.
