    Global Positioning System Based on a constellation of orbital satellites CDMA coding of the signal, different codes for

    civilian or military use Precision:

    Accuracy of ca. 18m technically feasible For civilians deliberately (!!) decreased to approx.

    100m accuracy at 95% probability 300m at 99.9% probability

    Used to get coordinates of visited sites during site surveys and locating measurements

    Watch out!!! Map datum and GPS datum must be THE SAME, otherwise bigger errors come out

    Digital Maps

    Layers of one block

    One pixel / unit

  • 34 NOKIA 6-60731/ RADIO NETWORK PLANNING TOOLS/ v 2.0

    Digital Map Data

    Pixel (map unit) is the smallest detail of a digital map

    Pixels are squares, defining the resolution of data

    The value of a pixel is an average over the area covered

    Typical resolution 2m... 500m

    All layers of a block have the same resolution

    A map can contain blocks with different resolutions

  • 35 NOKIA 6-60731/ RADIO NETWORK PLANNING TOOLS/ v 2.0

    Geographical Information Systems

    Computer system capable of assembling, storing, manipulating, and displaying geographically referenced information

    Layers of information

    Before the digital data can be analyzed, they may have to undergo other manipulations - projection conversions, for example - that integrate them into a GIS

    Datum (1/2) Geodetic datum (e.g. World Geodetic System 1984, WGS-84) defines

    an ellipsoid to transform potato-shaped earth surface to a plane surface. Any rectangular coord. system can then be used on a plane surface.

    Coord. transformation Lat/Long -> rectangular system: a combination of the Ellipsoid used + coordinate system used on plane surface. Most common combination (e.g. in GPS) is WGS-84 ellipsoid + UTM rectangular coord. system.

    Flat-earth models used for plane surveying

    Complex ellipsoidal models used for international applications describe the size, shape, orientation, gravity field, and angular

    velocity of the earth.

  • 37 NOKIA 6-60731/ RADIO NETWORK PLANNING TOOLS/ v 2.0

    Datum (2/2) Referencing geodetic coordinates to the wrong datum can result in

    position errors of hundreds of meters

    Different nations and agencies use different data

    The Global Positioning System is based on the World Geodetic System 1984 (WGS-84)

    Requires careful datum selection and careful conversion between coordinates in different data

    Complete datum conversion is based on seven parameter transformations

    translation parameters three rotation parameters and scale parameter

  • 38 NOKIA 6-60731/ RADIO NETWORK PLANNING TOOLS/ v 2.0

    Earth Models

    Ellipsoidal earth models are required to accurate range and bearing calculations over long distances compute position and waypoint information (Loran-C, and GPS

    navigation receivers).

    Reference ellipsoids are defined by major (equatorial radius) and minor (polar radius) semi-axes.

    Other reference ellipsoid parameters such as flattening, and eccentricity are computed from these two terms.

    The best of these models can represent the shape of the earth within about one-hundred meters.

    Lat/Long Coordinate System

    Latitude, Longitude, and Height system the most commonly used coordinate system reference planes: Prime Meridian and the Equator

  • 40 NOKIA 6-60731/ RADIO NETWORK PLANNING TOOLS/ v 2.0

    UTM Coordinate System

    Universal Transverse Mercator system defines two-dimensional, horizontal positions.

    UTM zone numbers designate 6 degree longitudinal strips extending from 80 degrees South latitude to 84 degrees North latitude.

    UTM zone characters designate 8 degree zones extending north and south from the equator.
