The CHCNAV APACHE 3 is a portable unmanned survey vessel with a single-beam echo sounder for bathymetric surveys, navigation channel surveys and riverbed mapping.
Its lightweight carbon fibre hull and shallow 10 cm draft support single-person deployment in lakes, inland rivers and coastal areas.
Integrated dual GNSS and IMU sensors provide accurate positioning, heading and motion compensation. Autonomous route following supports efficient data collection in changing water conditions.
The 200 kHz single-beam echo sounder measures depths from 0.1 to 200 metres, with stated accuracy of ±0.01 m + 0.1% of measured depth.
Powerful propulsion delivers speeds up to 6 m/s and up to 7 hours of operation at 1.5 m/s. Hot-swappable batteries support extended fieldwork.
Android-based EasySail software simplifies route planning, monitoring and data logging. Integrated 4G communication, panoramic video and obstacle avoidance support convenient survey operation.
