SPH Engineering Cerulean Surveyor 240-16 MBES (multibeam echosounder)

Description:

The Surveyor 240-16 Multibeam Echo Sounder (240 kHz MBES) is a compact, high-performance 240 kHz Multibeam Echo Sounder (MBES) designed for UAV-based hydrographic surveys. Optimised for seamless integration with UAVs like the DJI M300/M350/M400 RTK series, this unit is ideal for shallow water mapping and precision bathymetry missions.

This MBES features a 4° along-track transmit beam, 80° cross-track transmit beam, and a 16-element receive array. Unlike conventional beamforming systems, Surveyor leverages an advanced angle-of-arrival (AoA) estimation algorithm to deliver sub-degree angular resolution—resulting in significantly improved spatial resolution and target discrimination across a wide 80° swath.

Surveyor typically identifies 10–15 acoustic targets per ping within the swath, with accurate position and depth calculations based on precise range and AoA measurements. It includes a built-in IMU for pitch and roll correction, with heading and GPS coordinates sourced from the drone’s flight controller.

Note: Additional components (e.g., SkyHub, altimeter, GNSS input, UAV mounting, data logging, and visualization software) are required for full deployment. A tailored bundle can be quoted on request.
