    IntroductionField Tools, a field data collection software used on a hand-held

    controller for GIS data collection, is an extension of ArcPad. Field

    Tools for ArcPad is structured to provide the data collector with

    capture and update functions for geographical data in a wide range of

    GIS-related applications (Figure 1-1 on page 1-2).

    Field Tools uses the ArcPad shell from Environmental Systems

    Research Institute, Inc (ESRI) as the basis of features designed for

    Topcon receivers and controllers. Field Tools includes features for

    creating survey configurations, starting a Base Station, viewing

    tracked satellites, and switching between Bluetooth devices.

    Field Data Collection Overview

    Field data collection with the right GPS receiver can provide you with

    accurate and precise positioning, a requirement for any GIS project.

    This section gives an overview of GPS and receiver functions to help

    you understand and apply GPS principles, allowing you to get the

    most out of your receiver.

    GPS Overview

    The Global Positioning System (GPS) is a satellite-based line-of-

    sight radio navigation system run by the United States Department of

    Defense (DoD). This system offers a global, all weather, 24-hour

    positioning, velocity, and time service to any user equipped with a

    GPS tracking receiver on or near the Earths surface. At any giventime, with a standard 15 angle, up to 10 or 12 GPS satellites are

    visible from any point on earth. The Global Navigation Satellite

    System (GLONASS) is run by the Russian Federation Ministry of

    Defencea counterpart to GPS.

    Field Data Collection Overview

    P/N 7010-0824 1-3

    For information on current GPS constellation status, visit the U.S.

    Naval Observatory website (http://tycho.usno.navy.mil)/) or the U.S.

    Coast Guard Navigation Center website (www.navcen.uscg.gov). For

    information on the current GLONASS constellation, visit theGLONASS website (http://www.glonass-ianc.rsa.ru/pls/htmldb/

    f?p=202:20:1801996139495777::NO).

    Despite numerous technical differences in the implementation of

    these systems, both GPS and GLONASS have three essential

    components:

    Space GPS and GLONASS satellites orbiting approximately

    12,000 nautical miles above Earth and are equipped with a clock

    and a radio. These satellites broadcast digital information

    (ephemerides, almanacs, time frequency corrections, etc.).

    Control Ground stations located around the Earth that monitor

    the satellites and upload data, including clock corrections and

    new ephemerides (satellite positions as a function of time), to

    ensure the satellites transmit data properly.

    User The community and military that use GPS/GLONASS

    receivers and the corresponding satellites to calculate positions.

    Calculating Positions

    Each GPS satellite continuously transmits signals on two carrier

    frequencies known as L1 and L2 carriers. The L1 carrier is modulated

    with a Coarse Acquisition Code (C/A code) and a Precise Code

    (P code). The L2 carrier is modulated only with the P code. Also, a

    navigation message is modulated and transmitted on both

    frequencies.

    Once the receiver locks on to a satellite, it starts recording

    measurements and receiving the various digital information

    (ephemeris, almanac, and so on) the satellites broadcast. To calculate

    a position, receivers use the following formula:

    Velocity x Time = Distance

    Where Velocityis the speed at which radio waves travel (that is, the

    speed of light) and Timeis the difference between the signal

    transmission time and signal reception time.

    20/124

    Introduction

    Field Tools for ArcPad Reference Manual1-4

    To calculate absolute 3D positions (latitude, longitude, altitude) the

    receiver must lock onto at least four satellites. In a mixed GPS and

    GLONASS scenario, receivers must lock onto at least five satellites to

    obtain an absolute position.

    To provide fault tolerance using only GPS or only GLONASS, the

    receiver must lock onto a fifth satellite. Six satellites will provide

    fault tolerance in mixed scenarios. Usually, the number of GPS and

    GLONASS satellites in view does not exceed twenty (20).

    Once hooked onto a satellite, the receiver collects ephemerides and

    almanacs, saving this information to its NVRAM (Non-Volatile

    RAM).

    GPS and GLONASS satellites broadcast ephemeris data

    cyclically, within a period of 30 seconds.

    GPS satellites broadcast almanac data cyclically with a period of

    12.5 minutes; GLONASS satellites broadcast almanac data

    cyclically within a period of 2.5 minutes.

    GPS Positioning

    Achieving quality position results requires the following elements:

    Accuracy The accuracy of a position depends upon the number,

    signal integrity, and placement (also known as a Dilution of

    Precision, or DOP) of satellites.

    Differential GPS (DGPS) strongly mitigates atmospheric and

    orbital errors, and counteracts anti-spoofing signals the USDepartment of Defense transmits with GPS signals.

    The more satellites in view, the stronger the signal, the lower

    the DOP number, providing more accurate positioning.

    Availability The availability of satellites affects the calculation

    of valid positions. The more visible satellites available, the more

    valid and accurate the position. Natural and man-made objects

    can block, interrupt, and weaken signals, lowering the number ofavailable satellites.

    Integrity Fault tolerance allows a position to have greater

    integrity, increasing accuracy. Several factors combine to provide

    fault tolerance, including:

    Receiver Autonomous Integrity Monitoring (RAIM) detects

    faulty GPS and GLONASS satellites and removes them from

    the position calculation.

    Wide Area Augmentation System (WAAS) creates and

    transmits DGPS correction messages.

    Five or more visible satellites for only GPS or only

    GLONASS; six or more satellites for mixed scenarios.

    Current ephemerides and almanacs.

    Several algorithms to detect and correct faulty information.

    Conclusion

    This overview simply outlines the basics of GPS and GLONASS

    positioning. A number of differential positioning implementations

    exist, including post-processing surveying, real-time kinematic

    (RTK) surveying, maritime radio beacons, geostationary satellites

    (such as OmniSTAR service), and the wide area augmentation system

    (WAAS/EGNOS) service.

    DGPS Overview

    DGPS, or Differential GPS, typically uses the measurements from

    two or more remote receivers to calculate difference (corrections)between measurements, thus providing more accurate position

    solutions.

    With DPGS, one receiver is placed at a known, survey location and is

    referred to as the reference receiver or base station. Another receiver

    is placed at an unknown, location and is referred to as the remote

    receiver or rover. The reference station collects the range

    measurements from each GPS satellite in view and forms thedifferences (corrections) between the calculated distance to the

    satellites and the measured pseudo-ranges to the satellites.

    22/124

    Introduction

    Field Tools for ArcPad Reference Manual1-6

    These corrections are then built up to the industry standard (RTCM or

    various proprietary standards) established for transmitting differential

    corrections and broadcast to the remote receiver(s) using a data

    communication link. The remote receiver applies the transmittedDGPS corrections to its range measurements of the same satellite.

    Using this technique, the spatially correlated errorssuch as satellite

    orbital errors, ionospheric errors, and tropospheric errorscan be

    significantly reduced, thus improving the position solution accuracy

    of the GPS. The maritime radio beacons system is one example of this

    approach to connection GPS solutions.

    Another DGPS approach employs the geostationary satellites for the

    distribution of the corrections. One of the most widely used

    applications is the OmniSTAR Worldwide DGPS positioning service.

    RTK Service

    The real-time kinematic (RTK) method is the most precise method of

    real-time surveying. RTK requires at least two receivers collecting

    navigation data and communication data link between the receivers.One of the receivers is usually at a known location (Base) and the

    other is at an unknown location (Rover). The Base receiver collects

    carrier phase measurements, generates RTK corrections, and sends

    this data to the Rover receiver. The Rover processes this transmitted

    data with its own carrier phase observations to compute its relative

    position with high accuracy, achieving an RTK accuracy of up to 1 cm

    horizontal and 1.5 cm vertical.

    Coastal Navigation Beacons DGPS Service

    The maritime radio beacons system improve the accuracy of maritime

    navigation around harbors and critical waterways. These signals also

    cover some inland areas in proximity to the radio beacon station.

    In the United States, the coastal navigation beacons are managed by

    the United States Coast Guard and provide differential correctionservice in coastal areas and in much of the interior of the United

    States.

    addition, the geostationary satellites can be used for positioning as

    ordinary GSP satellites, improving system availability.

    WAAS provides accuracy performance of 0.60.7 meters horizontaland 0.91.0 meters vertical throughout the majority of the continental

    U.S. and large parts of Canada and Alaska. For more information on

    WAAS, visit the FAA website (http://gps.faa.gov/).

    The European Geostationary Navigation Overlay System (EGNOS) is

    a similar satellite system under development at the European Space

    Agency (ESA), the European Eurocontrol (EC), and the European

    Organization for the Safety of Air Navigation. For more information

    on EGNOS, visit the ESA website (http://www.esa.int/esaNA/

    egnos.html).

    Field Tools and GIS Systems

    Field Tools can be used with a number of data collectors, such as

    various hand-held, high accuracy receiver systems from Topcon

    (Figure 1-2). In these systems, Field Tools provides the mapping and

    GRS-1 Controller Device

    The GRS-1 hand-held controller incorporates digital imaging

    technology for capturing pictures. When capturing pictures usingField Tools for ArcPad, the image data includes GPS coordinates

    location (geo-tagged image) and other attribute information, such as

    azimuth, date and time of image capture.

    Image Capture Using the GRS-1

    Controller Device

    The GRS-1 receiver (Figure 3-63 on page 3-56) can be used as a

    stand-alone hand-held L1 device for mapping, or with the external

    PG-A1 antenna as a dual frequency RTK rover. When installing

    software or performing file transfers, the USB cable or Bluetooth

    module connects the GRS-1 to a computer for in-office processing.

    The GRS-1 can also be used as a controller for other Topcon

    NOTICE

    While creating a shapefile, the user must add a text

    attribute (length >50) for storing the path of the

    location of the image file on the GRS-1. For storing

    measured azimuth and tilt values, you must createrespective numerical attributes and set a precision

    (Figure 3-62).
