Drone Sonar Surveys: Depth Beyond Sight
What Is A Drone Sonar Survey?
A drone sonar survey is a method of collecting underwater data using a lightweight sonar device tethered to an unmanned aerial vehicle (UAV) or drone. This technique allows for real-time imaging and the creation of geolocated, interactive bathymetric maps without the need for a boat
The key components of a drone sonar survey include:
- Drone: An unmanned aerial vehicle (UAV) that carries the data sets the sonar system
- Sonar: An echo sounder or SONAR (Sound, Navigation, and Ranging) system that sends out sound pulses from just below the water surface to the ocean floor, and measures the time it takes for the pulse to return, determining the depth of the water.
- Data Processing Software: AI-based software that processes the collected data from sensors in the sonar system and creates bathymetric maps.
Drone sonar surveys are useful for various applications, such as hydrographic surveying, dredging operations, and underwater inspections. Some systems, like the Photoacoustic Airborne Sonar System (PASS), can be installed beneath drones to enable aerial underwater survey

Drone Sonar Sludge Measurement
Our drones equipped with sonar technology are being adapted for the process of sludge volume measurement in wastewater treatment.
By flying over restricted areas like ponds, lagoons, or tanks, these drones can accurately measure the volume of sludge and pinpoint areas of accumulation. The sonar system works by emitting a high-powered acoustic pulse, which reflects off the interface density selected, and the reflected signal is processed using specially developed software algorithms.
This allows for precise sonar measurement of sludge bed levels at the bottom of a clarifier or the lightest flocculent layer.

Drone Sonar River Channel Assessments
Drone sonar technology is a powerful tool for conducting River Channel Assessments. In such assessments, we are often seeking to understand the river’s depth, shape, and the characteristics of the riverbed, including the presence of any potential obstructions or hazardous materials.
Our sonar drones can determine the characteristics of the riverbed, whether it’s soft mud, hard rock, or littered with larger objects or debris. The gathered data can then be processed and used to create detailed maps or models of the site and river channel. These visual representations provide crucial information about the river’s conditions, including potential erosion areas, sedimentation zones, areas of ecological interest, and zones of potential flood risk.

Types Of Drone Sonar Survey Methods
Single-Beam Echosounder Surveys
Utilizing a single beam, these drone sonar surveys measure the water depth directly beneath the drone at a specific point.
The output of sensor data, including depth measurements, GPS coordinates, and timestamps, can be logged in a range of formats.
Notably, the accuracy of single-beam echosounders can be as high as 1cm +/- 0.1% of depth.
Side Scan Sonar Surveys
These surveys leverage a towed instrument to emit fan-shaped acoustic pulses, creating a series of swaths that combine to produce a comprehensive seafloor image.
The data collected reveals seafloor features, materials, and textures from acoustic backscatter response intensity.
The data files, primarily collected in XTF format, can be converted into other compatible formats.
Multibeam Sonar Surveys
Multibeam sonar systems register seafloor backscatter data, which are then processed into backscatter mosaics and angular responses for in-depth seafloor analysis. The data formats for these surveys depend on technical capabilities of the particular multibeam echo sounder system employed.
Besides, the raw data from these surveys can be further processed and visualized using specialized software to create detailed orthophotos, 3D models, elevation models, and point clouds.
Shaping the Future of Underwater Mapping
Aerial Sonar Debris and Object Detection
Our drone sonar survey service is a game-changer for debris and object detection in various water bodies. Equipped with high-resolution sonar technology, our drones emit sound waves that penetrate the water, bouncing off any object they encounter, be it natural or man-made. The time taken for the sound waves to return enables us to calculate the distance and size of the object, while the strength of the returning signal provides insights into its composition.
This technology allows us to accurately map the presence of underwater debris, discarded objects, potential hazards, and submerged infrastructures. By providing a detailed and comprehensive overview of the underwater environment, our drone sonar survey service aids in mitigating risks, planning clean-up operations, and ensuring the safety and efficiency of navigation and underwater activities.
Pioneering Precision: Drone Sonar Surveys
Aerial UAV Sonar For Sediment Mapping
At Drone Survey Services, we utilise drones equipped with tethered sonar systems to revolutionise sediment mapping. These drones carry sonar devices that emit sound waves towards the seafloor. The time it takes for these sound waves to bounce back to the sonar device provides us with crucial data about the depth and contours of the seafloor.
Not only this, but the strength and quality of the returned signal give insights into the composition of the seafloor, enabling us to identify different types of sediment such as sand, silt, clay, or gravel.
To further enhance the precision of our sediment maps, we can combine the sonar data with sediment samples and core samples taken from the seabed. This integration of data allows for the creation of comprehensive maps that detail the sediment composition and distribution across the seafloor.
