INTRODUCTION
1.3
Main Features
o
Bottom detection: The Echotrac E20 provides the most reliable and robust bottom tracking
available for precise and repeatable survey results. Its bottom tracking algorithms are based
on our multibeam and singlebeam experience and relies on the proven technology from
SeaBat, Echotrac, ParaSound, and HydroSweep sonars.
o
Built-In-Test-Environment (BITE): The BITE is an integral part of the sonar processing unit
monitoring the status of the internal electronic sub-systems. The BITE function is designed to
inform the operator that the system is performing normally and, therefore, that vessel time is
being utilized effectively. In the event of any errors, the operator is informed immediately for
prompt troubleshooting.
o
Dual channel: The Echotrac E20 dual-channel echosounder offers the full flexibility for
simultaneous two-channel survey operation in shallow waters.
o
Extended Range (ER): If deeper water surveys are required, or in environments, where more
acoustic power is required, the Echotrac E20-ER provides all the power needed, enabling
survey down to 6000m, a max. output of 2-3kW (depending on transducer), and longer
chirped pulses.
o
SBES User Interface: Intuitive user-friendly operator software.
o
Standard data output: The Echotrac E20 provides bathymetry and echogram data in a
standard format for easy interfacing.
o
Automatic operation mode: Based on the reflectivity of the seabed this mode automatically
optimizes all sonar settings. The Automatic mode maximizes the ping rate and optimizes
other sonar settings for bathymetry data acquisition by ensuring that returning echoes are not
saturated. The Automatic mode is designed to reduce operator workload and skill level
requirements, and thus reduce risk of operator error.
