Acoustic Doppler Current Profiler in Still Water

A SonTek ADCP in Shark Bay

Friendly Grab & Go ADCP 

The RS5 is an acoustic doppler current profiling (ADCP) system that fits in the palm of your hand and includes everything you need to make a discharge measurement. Get the package that includes the HydroBoardII Micro and you’ll have everything you need for the fastest, high-quality measurement possible. It is the smallest and lightest complete ADCP solution for moving boat discharge measurement available.

Simply fold the GNSS/antenna mast and pop the RS5 and board into the custom-designed backpack for easy transportation and minimal re-assembly between sites!

NEW! SonTek RS5 RTK  

This exciting new SonTek proprietary RTK solution uses custom-designed dual-frequency and multi-constellation GNSS antennas, with the option for a Rover and Base configuration, or a Rover antenna with NTRIP corrections. Other features include:

  • Supports constellations and frequencies GPS(L1ca/L2c), GLONASS(L1/L2), GALILEO(E1bc,E5b) and BEIDOU(B1i,B2i).
  • Provided boat track accuracy to 2cm.
  • Optional NTRIP or network RTK corrections directly through RSQ software.
  • Uses Lithium-ion rechargeable batteries (type 18650), also conveniently used with the RS5 ADCP. RS5 RTK systems come standard with four batteries - two needed for operation, and two spares.
  • Radio range of 250m, Rover-to-Base, line-of-sight.

RS5: Packed With All the Features You Expect 

As a member of SonTek’s RiverSurveyor® suite of instrumentation, the RS5 comes loaded with many of the advanced data collection capabilities, high-precision data quality, and flexible deployment options customers have grown used to over the years. The RS5 is no exception - take a look and compare for yourself! 

  • SmartPulse+, an intelligent algorithm utilizing Pulse-coherent and Broadband acoustic profiling that adjusts based on conditions
  • 360º compass and two-axis tilt sensor
  • Reliable bottom tracking and velocity profiling through a wide range of conditions and shallower than before
  • Batteries and Bluetooth radio are housed in the RS5, which means there is no need to connect to external electronics boxes. Rely on an integrated, modern, high speed, and low power wireless Bluetooth Low Energy (BLE5) radio, with 100m range and a five-minute data buffer to prevent data loss and redundant work.
  • Vertical acoustic beam for superior channel definition for the most accurate channel cross-sectional area, for discharge applications.

RSQ: Visualize Discharge Data Like Never Before

RSQ is a modern and user-friendly software interface. One measurement file includes all the data and metadata you need for each measurement. Export data to formats for Excel, Matlab, and Google Earth. Do more with less time utilizing improved site templates. Experiment, learn or teach in the office or conference room as though you were in the field with the “demo” mode to playback recorded files simulating live data collection. Flexibility is key with RS5! 

Now you can:
  • Save Data on a PC, external drive, or network 
  • Customize File Naming 
  • Run and apply Extrap directly
  • Sub-section transects 
  • Process *.riv / *.rivr files from RSL 
  • Choose three-beam switching when there is a vertical bank interface

Features
Vertical acoustic beam Superior channel definition for the most accurate channel cross-sectional area, for discharge applications. Measures the depth directly under the system and extends maximum discharge depth if bottom-tracking is out of range.
SmartPulse+® An intelligent algorithm utilizing Pulse-coherent and Broadband acoustic profiling that automatically adjusts based on conditions. Reliable bottom tracking and velocity profiling through a wide range of conditions and shallower than ever before. Visualize velocity data like never before with cell sizes down to 2.5 cm.
360º compass and two-axis tilt sensor Comes standard on the RS5 unit. Reports vessel heading, magnetic error and compensate for motion due to surface conditions.
Bottom-tracking Acoustically track vessel speed over ground independent of DGNSS. Also supplies secondary depth measurement.
SonTek RTK GPS (Option) Ultra-precise positioning as an alternative to bottom tracking in moving bed or other difficult situations. RTK (base + rover) and network RTK (rover only) capability down to 2cm accuracy. Simply connect an RTK antenna to your RS5 and start measuring!
DGNSS (Option) Integrated DGNSS smart antenna for a position as a backup or alternative to bottom tracking in moving bed or other difficult conditions. Geolocate each sample (or ensemble) during measurement. Utilizes multiple constellations for increased global precision (GPS, SBAS, GLONASS, BeiDou, GALILEO, QZSS).

SonTek RS5: Performance Evaluation Through Field Data

SonTek RS5: Performance Evaluation Through Field Data

During the development of the RS5, discharge measurements were performed at controlled sites with different systems commonly used for those sites and conditions.

This Technical Note introduces certain technical aspects of the RS5 and highlights its capabilities in the field by showing data comparisons using other ADCP systems at a wide variety of different sites. The data shown in this Technical Note were used in the development of the RS5 acoustic algorithms and to optimize the performance for shallow discharge measurements.
