PRODUCT DESCRIPTION
-
Rugged Hull Design
The APACHE 3 USV features a one-piece molded carbon fiber hull with 10 MPa strength and 60% improved impact resistance. A reinforced aluminum cover increases structural durability, while a 30% lighter design allows for easier single-person transport and deployment.
-
One-man Operation
With a 7 kg hull and 1 m length, the compact and lightweight APACHE 3 is easy to transport by car to remote survey sites. It can be operated by one person, increasing measurement efficiency and reducing labor costs.
-
Powerful Propulsion
The APACHE 3 is equipped with an 800 W motor capable of reaching 7200 RPM, enabling a top speed of 6 m/s. Its battery endurance allows up to 7 hours of continuous operation at a cruising speed of 1.5 m/s. Additionally, hot-swappable batteries support uninterrupted operation in the field.
-
High-accuracy Survey
Integrated GNSS and IMU sensors provide accurate position and attitude data, compensating for hull motion in survey results. Its next-generation bathymetric algorithms support adaptive parameter adjustments, ensuring reliable performance in dynamic riverbeds and diverse aquatic environments.
