Telesonar Underwater Acoustic Modems
|
 | Topside ATM-871
The ATM-871 topside modem and ATM-870 modem module serve as
the surface components of the bi-directional acoustic communication
system. These surface modems, configured with a remote dunking
transducer, transmit commands/data to, and receive commands /data from,
one or more subsea acoustic modems located on a seafloor instrumentation
package or AUV.
|
|
| Underwater Units
Benthos’ subsea acoustic modems serve as the underwater
component of the bi-directional acoustic communication link. Subsea
modems are interfaced with a host instrument or AUV, and acoustically
transmit/receive data from the host to the topside acoustic modem. Each
subsea modem is available in a variety of configurations including
customer-selected frequency range and integral or remote transducer.
|
|
| Transducers options
Benthos offers an array of transducers for integration with
our topside and subsea Telesonar modems. All Telesonar components are
capable of operating in one of three standard frequency ranges. Each
unit is configured to accepts these transducers in a remote or integral
configuration. |

activated by an acoustic command sent from the surface to the transponder.
The entire assembly is a self-buoyant package which will flip over from the
"transducer - up position" when deployed, to the "transducer
- down position" when released and floating on the surface. Two molded
handles in the hardhat are provided for ease of recovery and shipboard
handling.
Using the DS-7000 Deck Unit, the TR-6000 & XT-6000 can be commanded to

Geophysical Systems

Side Scan Sonar
|
| SIS-1500 - Chirp Digital Side Scan
Sonar
Single or Dual frequency Digital Chirp Side Scan Sonar.
Digitally synthesizes and transmits a linearly swept, frequency- modulated
(Chirp) pulse with resolution proportional to transmitted bandwidth—not
pulse length. The transmission of longer duration, wide bandwidth pulses
result in higher resolution sonar images and, because more energy is
projected into the water, greater SNR resulting in extended range. This
extended range and resolution provides for optimum system efficiency,
resulting in lower survey costs.
Available with SwanPro, the software
for geophysical data acquisition, processing and display. SwanPro acquires
and process data from all the Benthos' geophysical systems. SwanMosaic
is the data mosaicking software.
