The Surveyor 240-16 is a compact, low-cost multibeam echosounder perfect for the BlueBoat and other small USVs. It has a depth range of 50 meters and a built-in IMU to provide pitch and roll compensation for accurate results, even in rough water. Paired with SonarView software, the Surveyor generates real-time 3D point clouds of the seafloor for bathymetric surveys and mapping.

Includes mounting bracket and all hardware and cables needed for installation on the BlueBoat. Requires an Ethernet Switch onboard the BlueBoat for operation.

Product Description

The Cerulean Surveyor is a multibeam echosounder that transforms the BlueBoat into a powerful bathymetry and seafloor mapping machine. What sets the Surveyor apart from other multibeam sonars is its affordability, offering high-precision sonar technology at a fraction of the cost.

What is a Multibeam Echosounder?

A multibeam echosounder is a type of sonar used to map the seafloor or underwater terrain. Unlike a single beam echosounder, which only measures one point of depth directly beneath it, a multibeam echosounder captures many depth points at once to quickly map an area in detail.

Mapping the Depths

The Surveyor works by sending out 240 kHz sound waves in a wide 80-degree swath, allowing it to map large areas quickly. It then uses a 16-element receive array to listen for the returning echoes. By measuring the strength and time of each return, the system calculates the angle and depth of a wide swath of points on the seafloor from a single ping. It typically measures depths up to 50 meters below the vessel, with even greater range possible in ideal conditions.

Combined with the forward motion of the vessel, these depth points form a point cloud, which is used to create a detailed 3D map of the underwater terrain.

A built-in 9-axis inertial measurement unit provides pitch and roll compensation, so the movement of the BlueBoat won’t distort the data, even in choppy waters. The aluminum housing is depth rated to 300 meters, so it can also be used on AUVs (but this will require different parts!).
