1 Introduction to SonTek RiverSurveyor M9 &S5 River Discharge Measurement System Hoboken, NJ June 2012

2 New Doppler engine New transducer configurations New multiple frequency configurations New automated cell-size switching and signal processing (SmartPusleHD) New housings and power- communications modules New PC and mobile software New high-resolution GPS options New floating platform Advancements:

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 frequency 4 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 Range 0.3 to 5m referencing bottom tracking 0.3 to 15 m referencing GPS 2.4 diameter transducer housing Low-flow disturbance * Maximum profiling range can vary depending on conditions

6 RiverSurveyor M9 Mid-Range system 9 beams, tri-frequency, dual Janus array 4 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 range 0.3 to 30m referencing bottom-track 0.3 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 Hz –1 Mhz pings about 12 – 14 hz VB pings about 8 – 10 Hz 10-Hz GPS data is easily synchronized with S5/M9 data

8 Power & Communications Module Battery Compartment On/off button (w status light) Connector to M9/S5 Connector to power/com cable or dummy plug System/status lights

9 Power & Communications Module Drop-in replaceable/rechargeable 18v battery packs Battery charger Bluetooth or FreeWave 900-Mhz Communications Internal antennas Wet-mate connections 10-m cable and AC power supply for direct reading and external power Modules are fully independent of frequency and can be used with M9 or S5

10 Power and Communication Module (PCM) Telemetry Configurations Base Unit PCM Radio link only 2000-m range Base Unit Bluetooth dongle * 200-m range Base Unit Bluetooth mobile 60 m range Direct Connect to S5 or M9 Radio or Bluetooth Internal Antennas Rover PCM Rover PCM and corresponding Base unit are matched and configured at factory No possibility for data drops – internal ADP calculations and processing * Connects to laptop

11 RiverSurveyor Software PC and Mobile Based Moving-boat method –Data is stored on PC/Mobile Device and Instrument –Measurement can be started and stopped using different devices PC and Mobile Based Stationary-boat method (optional) –Data is stored only on PC/Mobile Device –Measurement can be continues after interruption –Ice-measurements –Measurement template included (for repeated measurements)

13 RiverSurveyor Mobile Platform Windows Mobile Utilizes Motorola Q phone Bluetooth telemetry – 60m range Extremely easy and robust Complete calculation on the fly. QA checks during data collection. Graphics for contour, ship-track, and profiles plots

14 RiverSurveyorMobile Platform Enables one person operation Protective enclosure provided for foul weather

15 S5 and M9 GPS Options Direct connect GPS (customer supplied) Allows use of existing GPS Specific requirements for operation with M9/S5 Differential capable RS232 output 10-Hz data rate (minimum) GGA/VTG NMEA strings SonTek Differential GPS For use in streams larger than 20-m in width SonTek 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 PCM SonTek provides antenna, mount, cable, and pole that attaches to top of S5/M9 ADP housing Setup is automatic once PCM box is powered. GPS lock time is typically within minutes. Useful in streams 20-m in width or larger

17 SonTek Differential GPS

18 SonTek RTK GPS RTK Base station PCM, tripod, and Radio telemetry GPS contained in rover PCM with additional radio link to RTK base station PCM. 1-mile range typical Automatic setup once PCMs are powered. Base-Station dose not require precise positioning. 10-Hz sampling rate Useful in streams 1-meter in width or larger
