CHCNAV Apache3 USV

CHCNAV Apache3 USV | Single Beam Marine Drone

The CHCNAV APACHE3 USV is a compact hydrographic unmanned surface vehicle (USV) designed for shallow water bathymetric surveys. It offers a lightweight and durable design, made from macromolecule polyester carbon fiber and Kevlar, and weighs just 7 kg without sensors. Its small, pocket-hulled vessel design allows it to operate efficiently in shoals, channels, and shallow rivers, making it ideal for marine survey and construction projects. The APACHE3 provides high accuracy, reliability, and ease of use, with advanced GNSS and IMU integration to maintain precision even under challenging conditions, such as passing under bridges where GNSS signals may be disrupted.

Key Features:

One-Man Operation:

• The APACHE 3 is designed for ease of use, allowing a single operator to handle on-site transport, installation, calibration, and mission processing. This makes it suitable for remote deployments where resources may be limited.

High-Performance Pocket-Hulled Vessel:

• The compact design of less than 1 meter in length enables it to navigate shallow waters without running aground. It also maintains hull balance even in rapid currents.

High Accuracy Under Bridges:

• The integration of GNSS and IMU sensors ensures accurate positioning and attitude data, compensating for hull sway. This system allows the APACHE 3 to maintain high accuracy even during temporary GNSS outages, such as when passing under bridges.

Absolute Linear Technology:

• The USV integrates high-precision GNSS positioning and heading technology, ensuring a straight sailing course in autonomous mode, even in complex current conditions.

Energy-Efficient Motor:

• The DC-injection rotary motor technology increases energy conversion efficiency by 40%, providing a high speed of 7,000 rpm. The motor is designed with anti-collision and anti-corrosion features, making it durable even in harsh marine environments.

Cost-Effective Echosounder:

• The built-in single-beam echo sounder is designed for bathymetric surveys of lakes, inland rivers, and coastal areas. It supports seamless 4G communication, eliminating the need for traditional network bridge base stations and making fieldwork more efficient.

Advanced Communication:

• Equipped with 2.4 GHz radio, network bridge, and 4G capabilities, the APACHE 3 supports real-time data communication and remote monitoring, ensuring reliable performance over long distances.

The APACHE 3 USV is a versatile, high-performance solution for bathymetric surveys in shallow waters. Its compact, lightweight design allows for easy transport and deployment, while its advanced GNSS and IMU integration ensures high accuracy and reliability even in challenging environments. The USV’s energy-efficient motor and durable construction make it suitable for extended use in various marine conditions. With its cost-effective echosounder and advanced communication features, the APACHE 3 offers a comprehensive and efficient solution for hydrographic surveying and marine construction projects.
