2050-DSS Side Scan and Sub-Bottom System 0024048_REV_A
Digital Telemetry Over a Single Coaxial Armored Tow Cable: The topside processor interfaces with the
towfish over an armored 10/100BaseT cable connection, using asynchronous digital subscriber line (ADSL)
modems.
Deep Water Operations: The system is rugged and rated to a depth of 2,000 meters. An optional Edgetech
armored cable provides digital telemetry over a single coaxial type cable up to 6,000 meters in total length.
Additional Payload Options: The 2050-DSS can be integrated with magnetometers, depth sensors,
altitude sensors, and a USBL responder.
ROV Mounting Option: The system components can be mounted on a ROV with a mounting kit.
1.2 Applications
Applications for the 2050-DSS Combined Side Scan Sonar and Sub-Bottom Profiling System are many, a
few of which are the following:
• Cable and Pipeline Surveys
• Geological/Geophysical Surveys
• Sediment Classification
• Pre/Post Dredging Surveys
• Archeological Surveys
• Scour/Erosion Investigation
• Marine Construction Surveys
1.3 Main System Components
The 2050-DSS Combined Side Scan Sonar and Sub-Bottom Profiling System consists of a rack-mounted
Starmux IV topside digital link, an attached computer with EdgeTech’s Discover 2050 software installed,
an armored tow cable, and the 2050-DSS Tow Vehicle.
1.3.1 2050-DSS Tow Vehicle
The 2050-DSS is a hydrodynamic towfish designed to accommodate multiple system payloads. The sonar
electronics are contained inside a single housing where side-scan transducer arrays and sub-bottom
transducers are attached. The towfish comes standard with either a 120/410/850 kHz and 2-16 kHz sub-
bottom profiler with PVDF receiver or a 230/540/850 kHz tri-frequency side-scan sonar configuration and
2-16 kHz sub-bottom profiler with PVDF receiver.
