Ship sonar EM2042 BNS

multibeamelectronicIP67

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

Designed for naval operations
EM2042 BNS is engineered for military and naval use, combining wideband multibeam performance with reinforced construction. Its capabilities support detailed seabed and water-column mapping to enable operations in complex and contested underwater environments while maintaining dependable operation under high loads and harsh conditions.

Precision navigation and awareness
By co-registering high-resolution bathymetry and backscatter, EM2042 BNS supports Terrain Referenced Navigation, seabed classification and change detection. Advanced signal and processing features—dynamic beam steering, motion compensation, nearfield focusing and pulse compression—ensure accurate data 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
Operating from 150 to 700 kHz and rated to 600 m depth, EM2042 BNS adapts to tasks from extended-range navigation to high-resolution inspection and object detection. Dual Swath and QuadSwath™ (Single RX) modes 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.
