Introduction to SonTek RiverSurveyor M9 &S5

1. Introduction to SonTekRiverSurveyorM9 &S5 River Discharge Measurement System Hoboken, NJ June 2012

2. Advancements: • 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

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 System/status lights On/off button (w status light) Connector to power/com cable or dummy plug Connector to M9/S5

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 arefully independent of frequency and can be used with M9 or S5

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

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 • 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 GPS contained in rover PCM with additional radio link to RTK base station PCM. 1-mile range typical RTK Base station PCM, tripod, and Radio telemetry
