Bathyswath-2 STD (B2S) 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 Underwater (B2U) 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

Bathywath-2 OMEGA (B2O) 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.

Bathyswath-2 OEM (B2OEM) 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
