Sonar boat Apache 3
TitleApache 3
The Apache 3 from CHCNAV is a compact, autonomous sonar boat designed for efficient bathymetric surveys. Developed for maximum mobility and ease of use, it combines modern GNSS/IMU technology with an integrated single-beam echo sounder—ideal for precise measurements in shallow and hard-to-reach waters.
TitlePrecise bathymetry for a wide range of applications
The Apache 3 is specifically designed for users who need a reliable yet cost-effective solution for hydrographic surveys. With its integrated single-beam echo sounder, the USV captures precise depth data in lakes, rivers, and coastal areas. Supported by dual-GNSS, IMU, and autonomous route planning, the system follows specified survey lines precisely and delivers consistent results even in currents or difficult conditions.
TitleCompact, durable, and portable
A particular focus is placed on mobility and operational flexibility: Weighing just around 7 kg and measuring one meter in length, the Apache 3 is easy to transport and can be operated by a single person. The robust carbon-fiber hull ensures both high stability and durability in daily use. Combined with a powerful drive system, long runtime of up to seven hours, and hot-swappable batteries, the system is ideally suited for extended surveying campaigns.
TitleIntuitive controls and a seamless workflow
The Apache 3 also prioritizes efficiency when it comes to operation: The Android-based EasySail software is integrated directly into the remote control, enabling full mission control without the need for additional hardware. Features such as live data display, video transmission, route planning, and data collection and processing ensure a seamless workflow—from planning to on-site analysis.
