1 Introduction to SonTek RiverSurveyor M9 &S5 River Discharge Measurement SystemHoboken, NJJune 2012
2 Advancements: New Doppler engine New transducer configurations New multiple frequency configurationsNew automated cell-size switching and signal processing (SmartPusleHD)New housings and power- communications modulesNew PC and mobile softwareNew high-resolution GPS optionsNew floating platform
3 S5 & M9 Acoustic Doppler Profilers Significantly faster ping rates (20-60 Hz) - robust and accurate measurements.Integrated multiple acoustic frequencies.Integrated acoustic vertical beam transducers – for depth.SmartPulseHD – transitions water-profiling automatically.Large internal recorder (8 Gb) - Discharge processing and data storage is done inside the ADP and in software.Increased Processing Power for discharge calculations, real-time data quality checking, on-line summary tables, etc…Dramatically improved bottom tracking resolution and precision.
4 RiverSurveyor S5 & M9 Enhancements for the user SmartPage Setup – Guided setup and configuration.SmartPulseHD – automatically adjusts water velocity measurement technique to adapt to changing river conditions. Requires “NO” user-based setup or configuration.Moving-bed tests – USGS “Loop-method” and USGS “SMBA-method” included in software.Redundant depth measurements with low-frequency vertical beam.High-resolution GPS system integration – ease of use and setup.
5 RiverSurveyor “S5” Shallow range system 5 beams, dual frequency4 beam Janus for velocity (3.0Mhz)1 centered vertical beam (1.0 MHz)Velocity profiling range (0.06 m to 5.0 m*)Vertical beam range (0.2 – 15 m)Discharge Measurement Range0.3 to 5m referencing bottom tracking0.3 to 15 m referencing GPS2.4” diameter transducer housingLow-flow disturbance* Maximum profiling range can vary depending on conditions
6 RiverSurveyor “M9” Mid-Range system 9 beams, tri-frequency, dual Janus array4 beam Janus for velocity (3.0Mhz)4 beam Janus for velocity (1.0 MHz)1 vertical beam (0.5 MHz)Velocity profiling range (0.06 m – 30.0 m*)Vertical beam range (80m)Discharge measurement range0.3 to 30m referencing bottom-track0.3 to 80 m referencing GPS* Max profiling range can vary depending on conditions
7 S5/M9 Measurement Distribution The S5/M9 pings up to about 80 Hz.Pings are distributed between Bottom-tracking (BT), Water Profiling (WP), Vertical-Beam (VB) to optimize measurements.Typically BT pings at 5 Hz.WP pings depend on frequency and depth.3 Mhz pings about 55 – 60 Hz1 Mhz pings about 12 – 14 hzVB pings about 8 – 10 Hz10-Hz GPS data is easily synchronized with S5/M9 data

11 RiverSurveyor Software PC and Mobile Based “Moving-boat” methodData is stored on PC/Mobile Device and InstrumentMeasurement can be started and stopped using different devicesPC and Mobile Based “Stationary-boat” method (optional)Data is stored only on PC/Mobile DeviceMeasurement can be continues after interruptionIce-measurementsMeasurement template included (for repeated measurements)
13 RiverSurveyor Mobile Platform Windows MobileUtilizes Motorola Q phoneBluetooth telemetry – 60m rangeExtremely easy and robustComplete calculation on the fly.QA checks during data collection.Graphics for contour, ship-track, and profiles plots
14 RiverSurveyorMobile Platform Enables one person operationProtective enclosure provided for foul weather
15 S5 and M9 GPS Options For use in streams larger than 20-m in width Direct connect GPS (customer supplied)Allows use of existing GPSSpecific requirements for operation with M9/S5Differential capableRS232 output10-Hz data rate (minimum)GGA/VTG NMEA stringsSonTek Differential GPSFor use in streams larger than 20-m in widthSonTek RTK (Includes base station)For use in streams larger than 1-m in width
16 S5 and M9 GPS Options SonTek Differential Solution GPS electronics are housed in rover PCMSonTek provides antenna, mount, cable, and pole that attaches to top of S5/M9 ADP housingSetup is automatic once PCM box is powered.GPS lock time is typically within minutes.Useful in streams 20-m in width or larger
18 SonTek RTK GPS Automatic setup once PCMs are powered. Base-Station dose not require precise positioning.10-Hz sampling rateUseful in streams 1-meter in width or largerGPS contained in rover PCM with additional radio link to RTK base station PCM.1-mile range typicalRTK Base station PCM, tripod, and Radio telemetry
