RESON launches a new version of the well-known SeaBat 7125 multibeam sonar systems designed especially 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 the transducer arrays allow 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 both data collection and processing times are reduced and maximizes surveying productivity 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 equi-angle or 512 equi-distant 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 sensor to calculate a TPE (Total Propagated Error). Soundings may be filtered by setting either the relevant IHO order or by defining custom vertical error limit.
Other new features in SeaBat 7125-Surface are roll stabilization, XYZ offsets, Quality filter and advanced diagnostics
SeaBat 7125-Surface will be introduced for the first time during the Shallow Survey 2008 conference and exhibition in Portsmouth, NH, USA this month. Live, on-water demonstrations of the system will be conducted throughout the Shallow water survey conmference
With the release of the SeaBat 7125-Surface dual-frequency multibeam echosounder, RESON again demonstrates continual developments and improvements in the SeaBat range of sonar systems.
