TOPODRONE AQUAMAPPER and TOPODRONE AQUAMAPPER NEXT are the payloads for high accuracy bathymetric measurements of water bodies, designed for DJI M300 / 350 quadcopters. TOPODRONE AQUAMAPPER includes several components that work together to provide safe drone flight and highly accurate geo-referenced bottom depth measurements. Data post-processing is performed in TOPODRONE Post Processing software in the AQUAMAPPER module.
The TOPODRONE AQUAMAPPER surface part consists of a payload carrier - a DJI M300 / 350 quadcopter, equipped with a high-precision radar to maintain the desired flight altitude, an underwater controller and an articulated boom mount.
The underwater part of TOPODRONE AQUAMAPPER consists of the main module TOPODRONE AQUAMAPPER, equipped with a bathymetric echo-sensor, as well as a high-precision GNSS receiver with an external GNSS antenna for geo-referencing the received data with an external GNSS antenna for geo-referencing of the received data. During TOPODRONE AQUAMAPPER operation, the main underwater module with ultrasonic bathymetric sensor is submerged at a depth of approximately 30 cm, and the GNSS antenna, rigidly mounted on a pole, is always in the surface position, which provides GNSS signal recording.
TOPODRONE AQUAMAPPER application areas
The bathymetric scanner is a solution for determining the depths of freshwater and marine areas, it perfectly combines high survey speed, efficiency and accuracy, successfully challenging traditional methods such as boats. Unlike unmanned surface vessels, TOPODRONE AQUAMAPPER, working in conjunction with a quadrocopter, allows to perform bathymetric measurements in water bodies with limited access from shore, as it does not require operators to go into the water. Also TOPODRONE AQUAMAPPER can be assembled and prepared for operation within 5 minutes, and travel to the required starting point and return to the starting point is performed by air.
- Determination of depths up to 200 m for design for laying communications.
- Inspection of sediments at the bottom of artificial reservoirs.
- Tracking changes in reservoir volumes.
- Monitoring of water transportation routes to control the passability of vessels.
- Mapping of water bodies for drawing up fishing charts.
AQUAMAPPER Next features
Swiss made
The device design, printed circuit board fabrication and software development are carried out in Switzerland. The production of scanners is small batch and factory production.
Control from the drone remote control
Output bathymetric profiles on the remote control, the ability to change the echo sounder settings (sensitivity, depth of measurement, frequency of operation), start and stop recording, see the quality of GNSS signal, measure water temperature and determine angular positions.
Operation without launching
It is possible to launch the complex from a remote part of the shore without the need for manual launching, thus it is possible to work even in very difficult conditions and toxic environment, the drone provides a high speed of up to 10 m/s when approaching the launch point of the mission.
Protected housing
The body of the AQUAMAPPER Next is made of anodized aluminum, which allows it to perform in active chemical environments without being susceptible to corrosion.
Shallow water operation
The device is submerged by only 20 cm during operations, allowing you to survey even in shallow water areas.
High speed of operation
Recommended bathymetric survey speed up to 3.5 m/s.
Wave and salt water resistance
The AQUAMAPPER Next can shoot in waves up to 1 meter and is saltwater resistant.
High data accuracy
At depths up to 10 m the accuracy in post-processing is 2-3 cm, at depths up to 50 m the accuracy is up to 20 cm.
Non-PPK operation
The AQUAMAPPER Next operates in PPK mode and does not require a permanent connection to the base station to receive corrections.
Quick preparation for operation
It takes approximately 3 minutes to prepare the kit for operation.
Proprietary software
Proprietary software for post-processing of data, which builds a point cloud with information about the bottom topography, and also takes into account the temperature and salinity of the water at the time of measurement, the data are corrected with this information in automatic mode. Added the possibility of user input of sound propagation velocity in the medium.
Combined imaging
TOPODRONE solution line allows to perform combined survey - to obtain bathymetric data on water bodies relief and to perform airborne and mobile laser scanning of the coastal part, and then to combine the obtained point clouds to analyze and form a general picture.
Drone Integration
Full integration with DJI Matrice 350/300 RTK drones, integration with other platforms via Mavlink protocol.
Lifetime warranty and prompt technical support
Each scanner is delivered with an instruction manual, and almost 100% of all users receive 4-day in-person training on scanner operation and data processing with practice in the field and issuance of a certificate of advanced training. The warranty period is 12 months for the device and all internal components, and the motherboard, which is manufactured by us in Russia, is guaranteed indefinitely. Technical support is provided for any questions related to the equipment and processing of the received data via e-mail, phone and messengers.
