As more and more individuals have to travel for work, travel and a myriad of other reasons, it has become somewhat of a priority to have the best technological device to help them get from one point to the next. As a result of this GPS Units have become exceedingly important, especially for those who are on the road on a daily or weekly basis. That is why "How To Pick The Perfect Portable GPS Unit" is a must for every consumer. Gone are the days when printed maps are used to find out just which way to go, not to mention that they tend to become outdated pretty quickly as more and more changes are made to the infrastructure. In this day and age electronic devices are needed to help the user to select the fastest route to their destination. They are pretty user friendly and can easily be updated.
Satellite navigation receivers are used to receive, process, and decode space-based navigation signals, such as those provided by the GPS constellation of satellites. There is an increasing need for a unified open platform that will enable enhanced receiver development and design, as well as cost-effective testing procedures for various applications. This book and companion DVD provide hands-on exploration of new technologies in this rapidly growing field.
One of the unique features of the work is the interactive approach used, giving readers the ability to construct their own Global Navigation Satellite Systems (GNSS) receivers. To construct such a reconfigurable receiver with a wide range of applications, the authors discuss receiver architecture based on software-defined radio (SDR) techniques. The presentation unfolds in a systematic, user-friendly style and goes from the basics to cutting-edge research.
Additional features and topics include:
* Presentation of basic signal structures used in GPS and Galileo, the European satellite navigation system
* Design and implementation of a GPS signal generator
* Presentation and analysis of different methods of signal acquisition-serial search; parallel-frequency space search; and parallel-code phase search-as well as code/carrier tracking and navigation data decoding
* A complete GPS software receiver implemented using MATLAB code as well as GPS and GIOVE-A signal records-available on the companion cross-platform DVD-allowing readers to change various parameters and immediately see their effects
* MATLAB-based exercises
* A hands-on method of testing the material covered in the book: supplementary front-end hardware equipment-which may be purchased at http: //ccar.colorado.edu/gnss-enables readers working on a Windows or LINUX system to generate real-world data by converting analog signals to digital signals
* Supplementary course material for instructors available at http: //gps.aau.dk/softgps
* Bibliography of recent results and comprehensive index
The book is aimed at applied mathematicians, electrical engineers, geodesists, and graduate students. It may be used as a textbook in various GPS technology and signal processing courses, or as a self-study reference for anyone working with satellite navigation receivers.
This book examines changing Soviet and Russian press coverage of the United States from the emergence of Mikhail Gorbachev as General Secretary of the Communist Party through Boris Yeltsin's re-election as Russian President and onward to the Putin Era. Becker argues that, owing to the absence of a language to support the reform strategy, the Soviet press presented positive images of its chief ideological and military opponent, the United States, as a means of supporting political, social and economic reform. Indeed, journalists were so overcome by a desire to present a 'new America' that, if anything, the United States was idealized where it was once reviled. Becker suggests that the end of the Cold War and the emergence of a more self-confident Russia means that the symbolic and discursive significance of the United States for Russia has diminished. His conclusions come from a careful reading of the Soviet and Russian press over a ten-year period and from interviews with journalists and editors.
