OVERVIEW
The EdgeTech 6205s2 is a fully integrated swath bathymetry and dual-frequency side-scan sonar system
that uses multiple receive elements and one discrete transmit element to produce real-time high
resolution, side-scan imagery, and three-dimensional maps of the seafloor. The 6205s2 overcomes the
limitations of multibeam echo sounders (MBES) and interferometric systems in shallow water using
EdgeTech’s unique Multi-Phase Echo Sounder (MPES) Technology. This hybrid approach combines
beamforming and phase discrimination techniques to determine each sounding along the seafloor. With
the integration of EdgeTech’s Full Spectrum® CHIRP technology, the 6205s2 exceeds IHO SP-44, NOAA,
and USACE specifications for feature detection and bathymetric point data uncertainty.
EdgeTech’s MPES technology enables the 6205s2 to produce a wider and cleaner swath (over 200°) than
current technologies, resulting in superior coverage enabling faster and safer survey completion. In
addition, the 6205s2 concurrently rejects multipath effects, reverberation, and acoustic noise commonly
encountered in shallow water environments.
The 6205s2 provides simultaneous dual-frequency side scan sonar, operating at 520/850kHz,
850/1600kHz, or 520/1600 kHz. The bathymetry operates at either 520kHz or 850kHz.
Additionally, EdgeTech’s latest 2205 Electronics and Modular Arrays are utilized in the 6205s2, resulting
in an extremely lightweight design required for shallow water applications and vessels of opportunity. The
2205 electronics and arrays are mounted onto a streamlined body deployed over the bow or side or
underneath a crewed or uncrewed survey vessel. Sonar data is transferred from the transceiver to the
processing unit onboard via an Ethernet network interface.
The 6205s2 system and its available integrations offer a powerful and versatile acquisition system suitable
for many different survey applications. It includes an integrated sound velocity sensor. It interfaces with
most third-party acquisition and processing software packages, standard DGPS/RTK GNSS systems,
heading, motion, sound velocity profilers, and INS.
