HISAS2020 ACR 80
Synthetic Aperture Sonar
The HISAS2020 is the latest generation synthetic aperture sonar from KONGSBERG. It brings the extreme resolution and operational robustness of the HISAS family of sonars to a new set of platforms with easy to integrate digital transducers.

Designed for sub-centimeter insight
HISAS2020 delivers sub-centimeter synthetic aperture sonar resolution, enabling best-of-class object classification and highly detailed seabed understanding. With premium SAS imagery down to <10 x 10 mm resolution, the system provides exceptional clarity for mine countermeasures, infrastructure protection, and high-end environmental monitoring where confidence in object interpretation is critical.
Platform-agnostic
With digital transducers and standard underwater cabling, HISAS2020 is designed for easy integration across a wide range of platform. It supports AUVs, UUVs, towfish, USVs, submarines, and surface vessels, and can be integrated on platforms already operating KONGSBERG EM2042 or similar systems. Integrated in-mission processing and a total power consumption below 90 W make it equally suitable for medium-size uncrewed vessel and surface-based operations.
From surveillance to commercial survey
HISAS2020 combines ultra-high resolution imagery with precision bathymetry, supporting IHO S-44 Special Order compliance. Standardized data outputs such as GeoTIFF, XTF, and Kongsberg.all ensure compatibility with leading commercial survey software, including CARIS HIPS & SIPS and QPS Qimera. Multiple performance modes and acoustic colour options further enhance classification performance in complex and challenging environments.
