A propos du livre

Présentation de l'éditeur

Assisted Gps (Agps) has been developed to provide greatly improved capabilities, helping Gps work better and faster in almost any location. Offering a detailed look at all the technical aspects and underpinnings of Agps, this unique book places emphasis on practical implementation. The book reviews standard Gps design, helping you understand why Gps requires assistance in the first place. You discover how Agps enables the computing of a position from navigation satellites in the absence of precise time – a topic not covered in any other book. Moreover, you learn how to design and analyze a high sensitivity Gps receiver and determine the achievable sensitivity. The book provides detailed worksheets that show how to compute, analyze, and improve the processing gain from the input signal at the antenna to the signal after the correlators. These worksheets are used in the book to generate families of curves that completely characterize receiver sensitivity, parameterized in terms of front end noise figure, coherent and noncoherent integration times. From this work a law of achievable sensitivity is derived and explained in the book. This cuttingedge volume discusses special forms of assistance data, industry standards for Agps, and government mandates for location of mobile phones. You also find coverage of future global navigation satellite systems and how they can be designed specifically for instantfixes and high sensitivity. The book features numerous tables, worksheets, and graphs that illustrate key topics and provide the equivalent of a technical handbook for engineers who design or use Agps.
