ARK-N |
Alpha ARK-N is a compact unmanned survey boat (USV) for fast bathymetric depth mapping. It features a built-in 200 kHz echo sounder (0.15–100 m, upgradeable) with automatic operation, dual-antenna GNSS + IMU, and 4G (Nano-SIM) connectivity. Electric drive and a detachable 33V 45,000 mAh battery provide up to 7 hours endurance at 2 m/s—ideal for rivers, lakes, canals, and reservoirs.
