Shanghai, China, April 24, 2026. CHC Navigation (CHCNAV), a global provider of geospatial solutions, announced the release of the D60, a dual-frequency single-beam echo sounder engineered for unmanned surface vessel (USV) operations. Designed for hydrographic survey and bathymetric mapping workflows, the D60 combines an integrated motion compensation IMU with adaptive auto-tuning algorithms to support stable depth sounding in turbid water and in areas with rapid depth transitions.
The D60 operates at 200 kHz and 33 kHz to support depth measurement across a wide range of survey conditions. The dual-frequency echo sounder provides a measurement range from 0.2 m to 1,000 m, supporting shallow-water bathymetry as well as deeper-water profiling. This configuration is designed to help maintain dependable signal performance across varied underwater topography, including rivers, reservoirs, estuaries, and nearshore areas.
For USV bathymetry, vessel motion can degrade data quality. The D60 integrates an internal attitude sensor sampling at 100 Hz. Its real-time attitude compensation supports roll and pitch correction during data acquisition, helping maintain consistent bathymetric data while the platform is underway.
The D60 uses intelligent algorithms that monitor incoming echo signals and automatically update operating parameters within 0.2 seconds. Automated gain and range adjustment reduces manual tuning and supports consistent depth measurement when survey conditions change, including abrupt depth shifts and highly turbid waters.
Built as an integrated single-beam echosounder system with a 1.2 kg main unit, the D60 is designed to minimize payload impact on compact USV platforms and support fast installation and removal. When integrated with the CHCNAV EasySail software ecosystem, the D60 supports a one-person hydrographic survey workflow that includes data acquisition, real-time visualization, post-processing, and file export from the remote control.
