Geographical Positioning: Technologies and Performance / Edition 1

From stars to terrestrial networks and satellites

From outdoors to indoors

From ancient to future applications

From techniques to technologies . . .

The field of radionavigation signals and systems has seensignificant growth in recent years. Satellite systems are veryefficient, but owing to their limited exposure and/or availabilityin some environments, they do not cover the whole spectrum ofapplications. Thus, many other positioning techniques are beingdeveloped.

Now, Global Positioning presents an overview of the strengthsand weaknesses of various systems with a specific emphasis on thosethat are satellite-based. Beginning with a description of theevolution of positioning systems, the book provides detailedcoverage of the three main Global Navigation Satellite System(GNSS) constellations, discusses how to cope with indoorpositioning, defines development activities and commercialpositioning, and proposes a vision for the future of the field.

Special features of the book include:

  • Exercises to test and challenge the reader's understanding

  • Direct comparison between constellations and other positioningsystems

  • Mathematical content kept to a minimum in order to maximizeaccessibility and readability

  • Descriptions of European and U.S. discussions for Galileo

  • Historical aspects and links between the distant past andcurrent systems

  • Footnotes that provide hints and comments to the reader

At a time when the positioning domain is experiencing suchimmense transformation, it is vital to have a solid understandingof the fundamental principles, current tech-nologies, and futureimprovements that will help estimate the performance andlimita-tions of existing systems. Global Positioning fills animportant need for professionals and students in a variety offields who want a complete and authoritative overview of globalpositioning techniques.
