Bathyswath-3
Bathyswath-3 has a completely new design and electronics platform giving improved performance in a fully integrated system.
Small, compact and innovative, the Bathyswath-3 goes beyond the performance of the Bathyswath-2 with these new features:
▪ Wideband (chirp) sonar technology
▪ 3 sonar frequencies simultaneously, in bathymetry and sidescan
▪ Fully integrated bathymetric system (sonar, INS/MRU, GNSS, Sound Velocity Sensor, Single-board computer)
Different configurations for different uses
- B3A : Bathyswath-3 ALPHA Subsea Unit (Fully integrated solution)
- B3S : Bathyswath-3 SIGMA (sonar only solution)
- B3OEM : Bathyswath-3 OEM (sonar only solution in OEM configuration)
Bathyswath-3 ALPHA (B3A)
Fully integrated solution
Bathyswath-3 ALPHA (B3A) has an integrated module for mounting on a pole over the side of a boat, including INS for motion sensing, GNSS for measuring position, a Sound Velocity Sensor, and an integrated single-board computer to aid integration with external software packages.

Bathyswath-3 SIGMA (B3S)
Sonar only solution

Bathyswath-3 SIGMA (B3S) has been designed for applications that need a small sonar package. It is ideal for use on small USVs, or on a lightweight survey pole.
The sonar electronics is integrated into the sonar head, so a small, flexible cable is used to connect it to the surface.
If the vessel or vehicle has its own computer, motion, and navigation sensors, then the Sigma box can be directly connected through the power, Ethernet, and timing connections in its cable.
If an integrated system is needed, then the ITER Systems Navbox is the perfect companion to the Sigma transducer.
