CHCNAV HQ-400 Compact Multibeam Echosounder
- Compatible with the CHCNAV Apache 4
- Lightweight Integrated Multi-Beam Echosounder
- Compact design: 2.7 kg, 12.5 cm
- Integrated IMU for roll, pitch, and yaw
- Combine sonar, temperature, attitude, positioning, and heading.
- Suitable for both manned survey boats and small unmanned surface vehicles
- Ideal for River and Lake Topography, Tailings Pond Survey, Port Terminal Survey, Channel Dredging, etc.
High-Resolution Data Collection
Capture detailed underwater topography with the HQ-400’s multibeam sonar. Its 512 beams (maximum 1024) provide high-resolution data for precise mapping and analysis, ensuring accurate bathymetric surveys.
High-precision positioning
The integrated attitude sensors and temperature sensors ensure accurate depth measurements and compensation for roll, pitch, and yaw. The Post-Processed Kinematics (PPK) solution provides reliable data, mitigating the effects of poor GNSS signal reception or water turbulence.
Calibration-Free Operation
The HQ-400 features a pre-calibrated IMU for roll, pitch, and yaw, eliminating the need for field calibration. Reduced setup time improves operational efficiency, enabling surveyors to focus on data collection and meet project deadlines.
Versatile Functionality
Perform a wide range of underwater survey tasks with the HQ-400’s advanced features. The system supports tilt measurement, real-time roll stabilization, near-field focusing, and water column imaging.
Comprehensive Software Ecosystem
CHCNAV CMS for PC and EasySail for Android offer advanced intelligent surface filtering, noise point removal, and flexible data display options, ensuring efficient survey management and high-quality results. Optional Qinertia PPK software enhances the accuracy of GNSS/INS data across a wide range of applications.
Compact and Portable Design
Easily transport and deploy the HQ-400 with its lightweight (2.7 kg) and compact (12.5 cm cubic shape) form factor. This design makes it suitable for both manned survey boats and small unmanned surface vehicles (USV), enhancing operational flexibility.
