Cerulean Surveyor 240-16 MBES Multibeam Echosounder

The Cerulean Surveyor 240-16 MBES is a cutting-edge 240 kHz multibeam echosounder (MBES) designed to deliver accurate underwater topography and depth measurements.

With a sophisticated 16-element receive array and advanced angle-of-arrival processing, the Surveyor 240-16 is ideal for applications demanding high-resolution bathymetry in shallow to moderate depths - up to 50 meters.

Optimized for use on mid-size UAVs, this compact MBES is a powerful tool for hydrographic surveys, waterway inspection, underwater mapping, and environmental monitoring.

Key Features

• High-Frequency Acoustic Sensing: 240 kHz operating frequency provides excellent resolution and bottom definition.

• Advanced Angle-of-Arrival Estimation: Achieves sub-degree angular resolution across a wide swath, outperforming conventional beamforming.

• Wide Swath Coverage: 80° cross-track transmit beam allows Surveyor to detect 10–15 targets per ping across swath.

• Precise Range & Angular Data: Combines time-of-flight and angular estimation to provide accurate target positions and depths.

• Integrated IMU: Built-in inertial measurement unit supports pitch and roll compensation for stable, accurate measurements.

• Drone-Ready: Fully compatible with DJI M300 RTK, M350 RTK, and M400 RTK platforms, as well as comparable Pixhawk drones.

• Lightweight System: At only 2.4 kg including all components, the Surveyor is optimized for UAV integration.
