APACHE3 USV

The APACHE3 is a portable shallow-draft hull with a single beam echo sounder for bathymetric surveys of lakes, inland rivers, and coastal areas. The master control unit provides seamless 4G communication, removing the limitations of traditional network bridge base stations and transmission distances, making hydrographic survey easier. The APACHE3 USV combines a dual GNSS positioning and heading sensor, a stable and reliable hull attitude and an IMU sensor, allowing uninterrupted survey while passing below bridges. The high efficiency 5 m/s motors and absolute straight-line technology allow a fully automatic pre-determined course in autonomous mode under adverse current and flow conditions. ONE-MAN OPERATION : Allow one operator to cope with most of remote deployment conditions. Made of macromolecule polyester carbon fiber and Kevlar fiber-glass weighting 7 kg without sensors. It can be carried by a single person during the entire project from on-site transport, installation, calibration, and mission processing. MAINTAIN HIGH ACCURACY : Integrated IMU to overcome temporary GNSS outage. The integration of GNSS and IMU sensor provides accurate position and attitude data to compensate for hull sway on survey results. The Apache3 provides consistently high accuracy positions even during temporary GNSS outages while passing under bridges. Tight integration of GNSS and INS data eliminates outliers. MAKE SURVEY POSSIBLE IN MOST WATER CONDITIONS : High-efficiency maritime design propulsion. High-efficiency maritime design propulsion DC-injection rotary motor technology provides a 40% increase in energy conversion efficiency. The motor's high speed (7,000 rpm), anti-collision design with a sealed straw cover with oblique titanium alloy mesh and anti-corrosion design (resistant to one month's immersion in sea water) make it extremely durable. ABSOLUTE LINEAR TECHNOLOGY : Maintain a perfect straight sailing course even in complex current conditions. Integrate high precision GNSS positioning and heading technology to ensure high accuracy bathymetric survey in fully autonomous mode. With less than 1 m length and pocket-hulled vessel design, the APACHE3 supports operation in shoals, channels, and shallow rivers for the bathymetric survey without run aground.
