SeaBat 7125 is Latest Multibeam System From Reson
Display and transducers for the SeaBat 7125-Surface.
The most notable change is a transceiver that combines the function of sonar processor and interface unit, removing the need to install the LCU bottle used in the deep-rated SeaBat 7125 systems. Cable length of 25 meters (standard) or 50 meters (optional) between the transceiver and the transducer arrays allow simple installations on most small vessels.
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 maximize surveying productivity using SeaBat 7125-Surface from surface vessels. These include:
• single or dual-frequency operations (200kHz and/or 400kHz)
• a ping rate of 50Hz (range dependent) with 256 equi-angle or 512 equi-distant beams per swath for high data density.
• advanced signal processing and bottom detect routines
• 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 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 proc-essing on the same hardware platform. Four video outputs allow multiple user and helm displays.
Variable swath coverage of up to 128 degrees to a maximum range of 500 meters offers the preferred combination of swath and resolution. A real-time uncertainity output from the SeaBat 7125 may be used in PDS2000, along with in-formation 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 was introduced during the Shallow Survey 2008 conference and exhibition in Portsmouth, New Hampshire in October. Reson conducted on-water demonstrations of the system throughout the conference. Edit Module
