Take measurements of depth, current and water quality using our aerial and aquatic drones, creating digital models of the underwater terrain without manual intervention on site.
Automated missions guarantee dense, comprehensive and accurate data, even in dangerous or hard-to-reach areas.
LiDAR and echo sounder surveys possible in areas not navigable by aerial drone
Built-in RTK for centimetre-level accuracy
Automatic obstacle detection, unmanned remote-operated mission
Measurement of reservoir volumes, monitoring of mining discharges, sediment control, inspection of hydraulic structures, monitoring of siltation, safety of flood zones
Mapping and monitoring of waterways, inspection of port infrastructure, surveillance of coastal areas, management of nautical access and safety of facilities
Monitoring erosion, turbidity, water quality, ecological impact on aquatic environments, integration into GIS for water management and development
Four technologies: boats (USVs), submarines (ROVs), multirotors, and aircraft (VTOLs), to meet the needs of all your bathymetric projects.
Versatile multirotor models, designed for accurate surveys on small bodies of water or in areas that are difficult to access.
Without coming into contact with the water, it allows point-by-point surveying even in the presence of algae, obstacles or strong currents (over 5 m/s).

Innotech-drone trains you in the use of drones and their sensors, from commissioning to processing and standardising the data collected. We accompany you in the field to guide you during your first mission.
Les bassins de rétention miniers de Rio Tinto étaient impraticables pour toute embarcation classique : boues épaisses, zones peu profondes, courants, crocodiles. Innotech drone a déployé un bateau autonome et un drone multirotor à sonde immergée pour couvrir l’intégralité de la zone, depuis la berge, avec une précision centimétrique.
As part of its operations in Madagascar, Rio Tinto needed to precisely map the bottom of vast retention basins to manage its dredging operations. Access was made impossible by surface conditions: thick mud, shallow depths, currents and the presence of crocodiles. No conventional method could cover the entire area. Innotech drone designed a tailored approach combining two complementary autonomous platforms, without a single operator leaving the bank.
Drowning, exposure to mining sediment contamination, current hazards: zero risk throughout the entire mission. Operators pilot from the bank with real-time visualization of the bathymetric profile. Local teams trained on-site conduct missions in full autonomy, with no external expert intervention.
The USV100, equipped with RTK GPS, a precision echo sounder and ADS-B, covers large surface areas in continuous navigation. It measures river water flow to monitor the impact of mining activity pollution on downstream rivers. The multirotor drone with an immersed dual-frequency precision echo sounder takes over in muddy and shallow sectors beyond the vessel’s reach. It enables sediment measurement. The result: no area left unsurveyed, georeferenced XYZ files directly usable for volume calculation, with no additional processing.
Under-dredging exposes Rio Tinto to environmental and regulatory risk. Over-dredging represents a direct operational cost overrun. The precision of the calculated volumes eliminates this margin of error and optimizes every dredging operation. Auditable data holds up under regulatory scrutiny, providing direct compliance value for a publicly listed group.
