CHC Navigation has released the HQ-400, a compact, high-resolution multi-beam echosounder designed for underwater mapping, offering advanced imaging, and real-time stabilization for hydrographic and bathymetric surveys.
The HQ-400, is ideal for a wide range of USVs (uncrewed surface vessels). The system features integrated sonar, temperature sensors, compass and pre-calibrated IMU, and provides flexible installation options for quick and easy setup and deployment.
Capabilities for High-Resolution Surveys
The HQ-400 features 512 beams, digitally expanded to 1024, and offers a swath coverage of 140°, delivering centimeter-level resolution for underwater mapping and environmental monitoring. It supports a depth range of 0.2 m to 150 m, making it ideal for inland and coastal survey applications, including marine research, coastal engineering, underwater inspections, and habitat mapping.
Advanced Features for Optimal Performance
The HQ-400 offers real-time roll stabilization, side-scan imaging, and water column imaging to maintain consistent data quality in challenging conditions. Its pre-calibrated IMU (Inertial Measurement Unit) removes the need for field calibration, reducing setup time and increasing efficiency. Advanced signal processing algorithms further enhance the accuracy and reliability of the collected data.
Versatile and Compact Design
With dimensions of 12.5 cm per side and a weight of only 2.7 kg, the HQ-400 can be used on manned survey boats and unmanned surface vessels (USVs). It integrates sonar, temperature sensors, attitude sensors, positioning systems, and a compass into one unit, eliminating the need for additional devices and increasing operational flexibility. Its durable design ensures reliable performance in harsh water environments.
Comprehensive Software Ecosystem
CHCNAV provides a complete software suite for the HQ-400, including CMS for PC for data acquisition and post-processing, and EasySail for Android for real-time monitoring.
The system is compatible with third-party software such as BeamworX and Hypack, offering users with flexibility for data processing, analysis, visualization, and reporting.
Taxiya Wang, Product Manager at CHC Navigation, commented, “The HQ-400 marks an important milestone in CHCNAV’s marine surveying solutions. This compact multibeam echosounder provides high-resolution data for accurate and efficient seafloor mapping. With its versatile and user-friendly design, the HQ-400 brings advanced technology to hydrographic professionals in a compact package.”
