Dual-frequency Echo Sounder for Drone System

Dual-frequency Echo Sounder for Drone System

Drone-based bathymetry offers a powerful and versatile tool for collecting detailed and accurate bathymetric data in various environments. Its efficiency, safety, and cost-effectiveness make it an increasingly attractive option for various applications in hydrography, environmental science, and engineering.

Description

The system includes:

  • A commercially available drone like DJI M350 RTK, DJI M300 RTK, M210, or M600 Pro (as well as drones based on the Pixhawk autopilot)

  • Echo sounder sensor on a rope

  • Radar altimeter to measure the precise altitude of the drone over the water surface

  • On-board SkyHub computer to control the mission and store geotagged measurements

  • UgCS Expert ground control software

    Dual-frequency Echo Sounder ECT D024s
    Type: Dual-frequency
    Acoustic frequency: 200 kHz / 450 KHz
    Measurement range*: 0.5 ~ 200m (200 kHz), 0.15 ~100m (450 kHz)
    Beam width, Conical (-3dB): 10° / 5°
    Weight of the echo sounder (in the air): 280g
    Weight of all components in the air (echo sounder, SkyHub, altimeter, housing, cables, mountings): 1.6 kg (light housing), 2.6 kg (heavy housing)
    Suitable DJI drones (or Pixhawk drones of comparable size): M210 (light housing), M300 RTK, M350 RTK, M600 Pro

    (*) The measurement range is from the bottom of the transducer. The practical minimum depth is around 15cm deeper because the sensor should be submerged during measurement.
