This is a portable shallow draft helmet equipped with a simple beam echo sounder, used for measuring water depth in lakes, inland rivers, and coastal areas. The main control unit provides seamless 4G communication, eliminating the limitations of traditional bridge base stations and transmission distance, and facilitating hydrological measurement.
The Apache3 USV combines dual GNSS positioning and orientation sensors, stable and reliable helmet posture, and IMU sensors, allowing for uninterrupted research while crossing bridges. The high-efficiency motor with a speed of 8 meters per second and absolute linear technology allow for fully automatic predetermined heading in autonomous mode under unfavorable current and flow conditions.
