The Tboat10-B-8 is Toknav's Type B water-quality monitoring configuration built on the Tboat10 unmanned surface vessel hull, a lightweight (~7kg hull, ~30kg total) carbon-fiber monohull rated for roughly 35kg of payload. It carries an 8-parameter water-quality sensor package alongside a single-beam echo sounder (200kHz, 8-degree beam angle) for combined water-quality and depth data collection, with multi-constellation RTK positioning (GPS/GLONASS/Galileo/BDS) for geo-tagged survey points. It suits small-to-medium ponds, reservoirs, and shallow inland waterways where a compact, remotely operated survey boat is needed.
