Airborne Bathymetric Survey

10x Faster & 2x Cost-Efficient

Acquire seamless bathymetry data of coastal and inland water.
An Unmanned Aerial Vehicle (UAV) - drone equipped with Echo Sounder is the best solution especially for hard to reach areas.

Book consultation Technology explained


Deploy anywhere

Ideal for hard to reach locations (steep coasts, mining pits, shallow waters, terrain obstacles), as well as waters of ponds, lakes, and canals. No need for a wide point of entry to the water for deployment/recovery. Locations not reachable by foot can be reached by drone.

Save time

Acquire data 10 times faster compared to the traditional methods due to easy transportation and fast deployment.

Operate in harsh conditions

The system works in an unsafe and hazardous environment, which a human should not approach freely. A drone operates without water contact, therefore lakes and rivers with strong currents, as well as contaminated waters become measurable.

Precise measurements

Drone's precise positioning while following the survey routes and ability to fly at a constant speed and specified low altitudes result in high accuracy measurements.

Supported Sensors

Echo Sounder

  • 450Khz single-frequency or 30-50 / 200Khz dual-frequency transducers
  • Maximum depth of 100-200m
  • Acquired data-sets: Echo Sounder datasets >>>

Ground Penetrating Radar (GPR)


The choise of the sensor is based on its technical capabilities and environmental conditions
  Echo Sounder Low frequency GPR
Maximum depth up to 200m up to 15m
Bathymetric survey of tailings dams and ponds
Bathymetric survey of ponds in open pits
Mapping the sediments of oxidation and tailing ponds
Bathymetry of ice-covered waters
only method for waters covered with ice
Strong current Not possible,
Echosounder has to be in the water

contact with water is not required
Mapping water depths and sediments before dredging and
cleaning of ponds, lakes, rivers, and canals
River and lake bottom profiling for scientific investigations
and environmental monitoring
Underwater inspections for engineering works
(bridge or pipeline crossings)
Sludge volume measurements at waste stabilization ponds

How it works

The integrated drone system for bathymetry consists of a drone (UAV) integrated with Echo Sounder or Ground Penetrating Radar (GPR). The full integration is ensured by adding the onboard computer UgCS SkyHub to the system. Adding a laser/radar Altimeter to the system enables the drone to precisely follow the terrain, based on the data received from the altimeter. The drone's flight is planned and managed using the full functionality of UgCS.

You can choose between a ready-to-use system or components like the UgCS SkyHub integration kit for self-assembling.
