Features

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.

With a 7 kg hull and total length of only 1m, the compact and lightweight APACHE 3 is easy to transport to remote survey sites. It can be operated by one person, increasing efficiency and reducing labor costs.

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.

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.

The APACHE 3’s remote controller comes pre-installed with the Android-based EasySail software, removing the need for external computers. The software includes real-time video transmission, parameter monitoring, and an integrated suite for path planning, data logging, and processing.
