CHC Navigation Releases RiverStar 3600D ADCP for High-Precision Hydrological Surveying

Shanghai, China – January 12, 2026 – CHC Navigation (CHCNAV), a global provider of geospatial solutions, announced the availability of the CHCNAV RiverStar 3600D (RS3600D), a compact acoustic Doppler current profiler (ADCP) designed for high-precision current measurement in rivers and inland waterways. The RS3600D supports hydrological surveying, river discharge measurement, ecological flow monitoring, and channel mapping across a wide range of water conditions.

Dual frequency ADCP performance for varied water environments

The RS3600D uses intelligent dual-frequency operation to support consistent profiling from shallow to deeper water. It coordinates an ultra-high frequency 3600 kHz channel with a 1200 kHz band, helping operators adapt measurements to site conditions without changing instruments. In shallow and slow-moving waters, the high-frequency mode supports low flow velocity measurement down to 1 cm/s and reduces the near-surface blind zone to 5 cm. This capability helps address environments where conventional profilers can be affected by signal noise and limited near surface data.

9-beam configuration with vertical beam depth measurement

In addition to current profiling, the RS3600D includes a dedicated 600 kHz vertical beam to improve depth measurement accuracy. The 9-beam configuration enables simultaneous acquisition of depth and velocity data, supporting efficient river cross-section surveying and bathymetric studies. The system supports a depth measurement range up to 100 meters and improves bottom tracking performance to help hydrographers build detailed channel profiles for hydrology and river engineering applications.

Compact ADCP for flexible deployment, including USV platforms

Designed for field mobility, the RS3600D measures 12 cm in diameter and weighs 2 kg. It can be deployed on multiple platforms, including unmanned surface vessels (USVs) such as the CHCNAV APACHE 4 series, as well as trimarans, cableway towing systems, and channel buoys. This flexibility supports different survey methods and operating constraints, from rapid spot measurements to repeat monitoring campaigns.

Streamlined software workflow for field control and post processing

The RS3600D integrates with CHCNAV software tools to support end-to-end hydrology workflows. The EasySail Android app provides field control and file transfer. HydroProfiler PC software supports post-processing, reporting, and long-term data management for hydrological testing and monitoring programs.
