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Gone are the days when printed maps are used to find out just which way to go, not to mention that they tend to become outdated pretty quickly as more and more changes are made to the infrastructure.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.
Today, increasing demands and expectations are being placed on GPS systems. Assisted GPS (A-GPS) 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 A-GPS, this unique book places emphasis on practical implementation. The book reviews standard GPS design, helping professionals understand why GPS requires assistance in the first place. Readers discover how A-GPS enables the computing of a position from navigation satellites in the absence of precise time - a topic not covered in any other book. Moreover, engineers learn how to design and analyze a high sensitivity GPS receiver and determine the achievable sensitivity of a GPS receiver.
This book investigates the history of national disunity in Germany since the end of the Second World War from a linguistic perspective: what was the role of language in the ideological conflicts of the Cold War and in the difficult process of rebuilding the German nation after 1990? In the first part of the book, Patrick Stevenson explores the ways in which the idea of 'the national language' contributed to the political tensions between the two German states and to the different social experiences of their citizens. He begins by showing how the modern linguistic conflict between east and west in Germany has its roots in a long tradition of debates on the relationship between language and national identity. He then describes the use of linguistic strategies to reinforce the development of a socialist state in the GDR and argues that they ultimately contributed to its demise. The second part considers the social and linguistic consequences of unification. The author discusses the challenges imposed on east Germans by the sudden formation of a single 'speech community' and examines how conflicting representations of easterners and westerners - for example, in personal interactions, the media, and advertising - have hindered progress towards national unity. German division and re-unification were crucial to the development of Europe in the second half of the twentieth century. This fascinating account of the relationship between language and social conflict in Germany throws new light on these events and raises important questions for the study of divided speech communities elsewhere. The book will interest sociolinguists, historians, sociologists, and political scientists.
