Bathymetry Survey
Precision underwater mapping using autonomous catamaran platforms and survey-grade echo sounders.
Advanced Hydrographic Ecosystem
Bathycat USV
The BathyCat is a compact catamaran‑type autonomous survey boat designed for bathymetric surveys. The catamaran configuration provides high stability on water and allows integration of sensors such as GNSS receivers and echo sounders.
The USV can be remotely operated or programmed to follow predefined survey lines, ensuring systematic coverage and observer safety.
Futaba T6K Transmitter
The BathuCat USV is operated using a Futaba long-range RC transmitter. The controller operates on 2.4 GHz frequency with 8-channel control and frequency-hopping technology to ensure stable communication during survey operations.
Provides smooth throttle control and reliable long-range communication, allowing precise navigation and maneuvering of the USV during bathymetric surveys.
Bathylogger BL200 Ecosounder
The BathyLogger BL200 is a survey‑grade single beam echo sounder designed for hydrographic surveys. It measures water depth by transmitting acoustic pulses toward the waterbed and calculating the return time of the echo.
The system records depth together with GNSS coordinates for accurate georeferenced bathymetric mapping, suitable for reservoir and river analysis.
Operational Excellence
The bathymetric survey is conducted using a BathyCat Unmanned Surface Vehicle (USV) equipped with the BathyLogger BL200 survey‑grade single beam echo sounder. The system enables safe hydrographic data collection in reservoirs, lakes, ponds, and rivers while the operator remains onshore. During the survey, the BathyCat USV navigates along predefined survey lines across the water body.
The BL200 echo sounder continuously records depth measurements while the GNSS receiver logs the geographic location of each observation. The collected data forms the basis for bathymetric surface modelling. This integrated approach ensures high-resolution depth logging suitable for bathymetric mapping and sediment analysis, fully compatible with GIS and hydrographic software for bathymetric surface generation.
