Bathyswath-2 STD system is our standard version, it consists of:

• The Deck Unit (DU) in painted and anodized aluminum. It is IP66 and includes the sounder electronics for 1, 2 or 3 transducers
• One, two or three transducers (117, 234 or 468 kHz choice)
• One, two or three cable extensions for the transducers (5, 10, 15 or 20m standard, more on request)
• A V-bracket (small V-bracket by default, it is only compatible with 234 and 468 kHz transducers; the big V-bracket is a necessary option for 117 kHz transducers or if you want to install, underwater between the transducers, a motion sensor and/or a sound velocity sensor)

To complete the bathymetric “package”, you will also need the following ancillary devices:

• A GNSS receiver
  – Double antenna for the heading value and PPS for the GPS time
  – RTK (Rover) or satellite correction services (Omnistar, Atlas, etc.) or GSM for centimetric position
• A sound velocity profiler and ideally, a sound velocity sensor near the transducers
• A motion sensor for heave, pitch and roll

Bathyswath-2 UW system is our underwater and integrated version, it consists of :

The Subsea Unit (SU) in titanium. It is waterproof to 300m (or 3000m in options) and includes:

• Sonar electronics for 1 or 2 transducers
• A communication and power board
• An optional INS or MRU (Ekinox A or E)
• An optional Sound Velocity Sensor (miniSVS)
• One or two transducers (234 or 468 kHz)

• An umbilical (20m by default, longer or shorter on demand)

To complete the bathymetric “package”, you will also need the following ancillary devices:

• A GNSS receiver
  – Double antenna for the heading value and PPS for the GPS time
  – RTK (Rover) or satellite correction services (Omnistar, Atlas, etc.) or GSM for centimetric position
• A sound velocity profiler for the speed of sound in the water column

Bathyswath-2 OEM is made for integration by clients in their own systems, which includes the following items:

• 1 to 3 transducers  (117, 234 or 468 kHz)
• 1 x Transducer Electronic Module (TEM) – Bare board set
• 1 x Data acquisition & 3D processing software (Unlimited licences, no PC is supplied)
• 1 x Data acquisition software for Linux or Windows (other operating systems available on request)
• 12 month return-to-base warranty and packaging.

Optional components include:

• An interface board, simplifying connection to the electronics
• Cable sets, with standard computer and power connectors
• Transducer extension cables
• Transducer mounting hardware

Bathywath-2 OMEGA provides sonar control, GNSS positioning, INS motion compensation, sound velocity measurement, and data acquisition and sonar processing and data acquisition in one compact package. Bathyswath uses wide swath widths; this increases survey speeds significantly, especially in shallow water.

• 3 sonar frequencies (117, 234 or 468 kHz), in bathymetry and sidescan.
• Low-power consumption.

Integrated OMEGA deck unit

One optional motion sensor (4 possibilities), one optional dual-antenna GNSS receiver for heading and positioning (3 possibilities) and two single-board-computers (one for sonar data acquisition and one for 4G communications & end-user needs).

3 different transducers: 117, 234 or 468 kHz.
