APACHE4 Unmanned Surface Vehicle (USV) with a Single beam Echo Sounder for bathymetry surveying of rivers, lakes, and reservoirs up to a depth of 200 m. It is well suited to areas where crewed boats are difficult or unsafe to operate. With GNSS+IMU navigation, the platform can follow planned routes and maintain stable positioning during measurements. This USV supports the integration of ADCP systems for flow and velocity measurements, and up to 40 kg payload. It has a 6.5 m/s maximum speed and battery endurance of 9.8 h @ 1.5 m/s.
DJI Matrice 400 drones with up to 59 minutes of flight time, a maximum payload of 6 kg, and can support for up to seven payloads simultaneously. It has IP55 weather protection, RTK positioning, and enhanced transmission up to 40 km, therefore supporting reliable operation in challenging field conditions.
RS-1200 is a high-accuracy ADCP designed for measuring water velocity, flow direction, and depth. It can be integrated with the APACHE4 USV. It uses a 5-beam configuration, and offers ±0.25% ±2 mm/s velocity accuracy, and operates in water as shallow as 30 cm.
The EchoLogger ECT D052S is a dual-frequency single-beam echo sounder for drone-based bathymetric and hydrological surveying. It operates at 50 and 200 kHz and provides measurement ranges of 0.5–200 m. It has integrated tilt/roll and temperature sensors. Dual-frequency capability supports both standard depth sounding and sediment-related measurements. The system is compatible with drones our DJI M400 UAVs.
The EchoLogger ECT D24S is a dual-frequency single-beam echo sounder for drone-based bathymetric and hydrological surveying in shallow, vegetation-rich water bodies. It operates at 200 and 450 kHz and provides measurement ranges of 0.5–200 m and 0.15–100 m, respectively. It has integrated tilt/roll and temperature sensors and is compatible with our DJI M400 UAVs.
Geolux RSS-2-AB water surface velocity measurement kit is a UAV-based solution for contactless measurement of surface water velocity. The system supports automated measurement at predefined survey points. This makes it well suited for hydrological surveys, discharge monitoring, irrigation-channel assessment, and other engineering or environmental applications requiring rapid, non-contact flow measurements. It is compatible wit our DJI M400 UAVs.
Geolux LX-80-AB is a radar water level sensor designed for contactless measurement of water surface elevation from UAV platforms. The sensor can be flown autonomously at altitudes of approximately 30–40 m along rivers and channels to generate water surface elevation profiles.
This Water Sampling System enables remote, automated water sampling from rivers, lakes, reservoirs, and other water bodies without requiring direct physical access or boat deployment. The system provides a sampling capacity of 1 L if combined with our M400 UAV. This system and its accompanying planning software allows the UAV to fly to a predefined location, descend to the required altitude, and trigger sample collection at a specified depth.
