RSQ Software: Your Tool to Help You Work Smarter with the SonTek-RS5

Whether you're in the field or back at your desk, RSQ software continues to evolve—giving you more ways to collect, process, and visualize data with ease. With its intuitive interface and flexible export options (Excel, Matlab, Google Earth, Kisters, AGILA), RSQ helps you make the most of every measurement.

  • Perform both moving boat and stationary measurements
  • Connect to Network RTK (NTRIP) for high-accuracy positioning
  • Use GNSS to measure station distances in stationary mode
  • Apply USGS Extrap to moving or stationary data
  • Sub-section and recalculate moving boat transects
  • Switch beams when needed to maintain measurement quality
  • Process data from SonTek’s M9 or S5 (.riv/.rivr)
  • Save data locally or to your external/network drive
  • Customize file names for easy organization

NEW! Now with RSQ version 3.2, we’ve added powerful new features designed with your workflow in mind:

  • Connect using your PC’s built-in Bluetooth – No external adapter required
  • New “Magnitude Method” for stationary measurements – More ways to measure, your way
  • Automatic extrapolation – RSQ now applies extrap for stationary data, saving you a step
  • Bug fixes and performance enhancements – For a smoother, more reliable experience

You can even replay recorded files to simulate live measurements—perfect for training or QA/QC in the office.

RSQ is a state-of-the-art software platform for performing discharge measurements with the SonTek RS5 system. Developed with ease of use in mind, RSQ offers a wireless BLE5 bluetooth connection to the RS5, configurable data visualization in the form of plots and tables, real-time QA/QC warnings and feedback, and fast discharge analysis during a measurement. In post-processing, RSQ allows the user to perform unique functions, including beam switching for 3-beam solutions, sub-sectioning transects, and applying Extrap (a USGS extrapolation tool). RSQ can also be used to post-process SonTek RiverSurveyor M9/S5 data files.
