High-Performance Compact Vessel
Fully Autonomous Navigation
Follow pre-set routes seamlessly with precise linear technology and dual GNSS positioning. The Apache 3 ensures a perfectly straight sailing path, even in challenging current conditions.
Precision Under Bridges
Achieve exceptional accuracy under bridges with advanced GNSS and IMU integration. The Apache 3 delivers precise position and attitude data, compensating for hull movement and eliminating errors during GNSS signal interruptions.
Single-Operator Efficiency
Weighing only 7 kg, the Apache 3 is designed for effortless transport and deployment by a single operator. From setup to mission execution, it streamlines operations, enhancing overall efficiency.
Durable and Robust Build
Crafted with macromolecule polyester carbon fiber and Kevlar fiberglass, the Apache 3 offers exceptional durability. Its sealed straw cover and titanium alloy mesh guarantee reliable performance in demanding conditions.
Use Cases
- Bathymetric Surveys: The Apache 3 excels in conducting bathymetric surveys, which involve mapping underwater topography to determine water depth and the shape of submerged terrain. Its high-resolution single-beam echosounder provides depth measurements with a range of 0.15 to 200 meters and a resolution of ±0.01 m + 0.1% x D, ensuring precise data collection for applications such as nautical charting, dredging operations, and habitat mapping.
- Navigation Channel Surveys: Maintaining safe and navigable waterways requires regular monitoring of channel conditions. The Apache 3’s shallow draft of 10 cm allows it to operate in confined and shallow channels, collecting data to assess sediment accumulation, identify potential hazards, and ensure compliance with navigational safety standards. Its autonomous operation and precise positioning capabilities enable efficient surveying of navigation channels.
- Riverbed Mapping: Understanding riverbed morphology is essential for flood management, ecological studies, and infrastructure development. The Apache 3’s compact design and high-performance capabilities make it suitable for mapping riverbeds, capturing detailed information on sediment types, underwater features, and depth variations. This data supports environmental assessments, engineering projects, and the management of aquatic habitats.
