Trimble R10 “Productivity” Beyond GNSS

1. 2. 3. 4. 5.

Trimble HD-GNSS Trimble SurePoint™ Trimble xFill™ Trimble 360 Ergonomic Design

“Pair with Trimble Access and Trimble Business Center for the most powerful total solution on the market”

1. Trimble HD-GNSS The next-generation processing technology for precise GNSS positioning that surpasses the older fixed/float technique • Precision-based measurements • Start measuring sooner • Shorter occupation times • Measure with confidence in more challenging environments


2. Trimble SurePoint™ An integrated tilt sensor enables faster measurements, increased accuracy and greater quality control  eBubble means all measurement information is in the same place  Guards against erroneous measurements due to pole tilt  Measure faster with automatic point measurement/storage  A new level of traceability in your survey data


Guards Against Pole Tilt • Guards against erroneous measurements due to pole tilt • A tilt warning appears if the pole is ever outside the user defined tilt tolerance during a measurement or at start/storage • This can be disabled


Auto Measure/Store • Hundreds of points can be stored with only one tap on the Start button • Measurement begins when tilt is within a pre-defined tolerance (default: 0.020m) • Auto-stored after two epochs – go to the next point…

0.010m

0.020m

0.030m


A New Level of Traceability • Surveyors want raw data • Tilt sensor values are stored with every point and can be reviewed in Trimble Business Center


3. Trimble xFill™

Powered by Trimble RTX™ Technology

Continue surveying without interruption when you temporarily lose connection with your base station or VRS network  More continuous surveying  Less downtime


Trimble Owned & Operated • Trimble xFill™ is a new Trimble RTX™-based technology that leverages a worldwide network of Trimble reference stations


Geo-Stationary Satellites • When you lose connection with your base station or VRS network, Trimble xFill™ uses positional information that is delivered to the Trimble R10 via overhead satellites


Specification • The Trimble xFill™ solution diverges over time – Horizontal: RTK* + 10mm / min – Vertical: RTK* + 20mm / min

• Your base station needs to be located within 1m of the WGS-84 coordinate. Using the “here” key requires an SBAS corrected position


4. Trimble 360 A powerful new tracking technology that is capable of supporting all existing and planned GNSS constellations and augmentation systems  Industry-leading 440 GNSS channel specification  More satellites means you can measure in more places  Future proof your investment


5. Built for the Surveyor A new level of precision engineering, the smallest and lightest GNSS receiver in its class  Packed with new features  40% smaller and 30% lighter  Rugged IP67 / MIL-STD-810F  Improved weight distribution  Improved handling means less fatigue after a day in the field


OmniSTAR™ • Provides real time differentially corrected positions without the need for a radio link • Included in every Trimble R10 • Requires a subscription

What is Underground Utility Mapping?  Accurately locate, map and store the position, depth and sometimes condition of a underground utility device, such as a cable, pipe ( gas, sewage, water etc )


A Historical Perspective Utility Infrastructure – 1897


“CAD” Circa 1897


Utility Mapping – 2013

Methods are distinguished between remote sensing (GPR, electromagnetic), and visual inspection


CAD 2013 (2-d)


Optimal Ranging – Spar system

Line or Sonde tracking

Capture 3-D geospatial positions

Self-documenting accuracy

Casual contact to centerline

Extended range using dual-spars


Spar Hardware  Two 3-d magnetic loop antennas  20 Hz – 10 kHz frequency  3-axis digital compass  3-axis accelerometer  Bluetooth or USB host interface  Zigbee (wireless sensor networking)  Model-based optimization processor  Quick-change 8-hr Li-Ion battery  USB software updates


Transmitter  Click to edit Master text styles  Second level  Third level  Fourth level  Fifth level

An essential element of the Optimal Ranging Utility Survey system is the transmitter. Except in the “passive” tracing of utility lines that already have current flowing (such as active AC power cables or pipelines carrying a cathodic protection signals), an “active” signal must be applied to the lines.
