High‑resolution multibeam mapping sonar for naval applications

The EM2042 Bottom Navigation System (BNS) is a flexible, wideband multibeam mapping sonar optimized for naval missions across the underwater battlespace. Designed for applications such as Critical Undersea Infrastructure Protection, Rapid Environmental Assessment, Mine Warfare, and operations with submarines and uncrewed platforms, EM2042 BNS delivers accurate bathymetry and backscatter data to support navigation, detection, and situational awareness. Built with reinforced titanium housings and subsea‑qualified electronics, the system is engineered for reliability in demanding operational environments.

Designed for naval operations

EM2042 BNS is purpose‑built for military use, combining robustness with high‑resolution performance. Its wideband multibeam capability supports detailed seabed and water‑column mapping, enabling naval forces to operate with confidence in complex and contested underwater environments. Reinforced construction ensures dependable operation in harsh conditions and high‑load scenarios.

Precision navigation and awareness

By co‑registering high‑resolution bathymetry and backscatter, EM2042 BNS supports Terrain Referenced Navigation, seabed classification, and change detection. Advanced features such as dynamic beam steering, motion compensation, nearfield focusing, and pulse compression ensure accurate data even on fast‑moving or unstable platforms. Real‑time processing and data fusion enhance detection, classification, and overall underwater situational awareness.

Flexible integration for any mission

With a 150–700 kHz frequency range and operation down to 600 m depth, EM2042 BNS adapts to a wide variety of naval tasks—from extended‑range navigation to high‑resolution inspection and object detection. Dual Swath and QuadSwath™ (Single RX) increase sounding density for faster, more detailed surveys. The modular design supports installation on surface vessels, submarines, and uncrewed platforms, with secure integration into WECDIS, naval consoles, and third‑party hydrographic software.
