Bathyswath-3 SIGMA-B (B3S-B) is fully integrated sonar system. It is ideal for use on small USVs, or on a lightweight survey pole.
The sonar electronics, INS, GNSS, and SVS are all integrated into the sonar head, requiring the use of a single umbilical cable to connect it to the surface.
If the vessel or vehicle has its own computer, motion, and navigation sensors, then the Bathyswath-3 Sigma-A system is suggested.
