E-BOOK EXCERPT

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 seen significant growth in recent years. Satellite systems are very efficient, but owing to their limited exposure and/or availability in some environments, they do not cover the whole spectrum of applications. Thus, many other positioning techniques are being developed. Now, Global Positioning presents an overview of the strengths and weaknesses of various systems with a specific emphasis on those that are satellite-based. Beginning with a description of the evolution of positioning systems, the book provides detailed coverage of the three main Global Navigation Satellite System (GNSS) constellations, discusses how to cope with indoor positioning, defines development activities and commercial positioning, 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 positioning systems Mathematical content kept to a minimum in order to maximize accessibility and readability Descriptions of European and U.S. discussions for Galileo Historical aspects and links between the distant past and current systems Footnotes that provide hints and comments to the reader At a time when the positioning domain is experiencing such immense transformation, it is vital to have a solid understanding of the fundamental principles, current tech-nologies, and future improvements that will help estimate the performance and limita-tions of existing systems. Global Positioning fills an important need for professionals and students in a variety of fields who want a complete and authoritative overview of global positioning techniques.

Readers find here a volume that applies positioning theory in order to achieve a fuller and more in-depth understanding of conflict and its psychological resolution. Positioning theory is the study of the nature, formation, influence and ways of change of local systems of rights and duties as shared assumptions about them influence small scale interactions. This book will thus be of interest to social psychologists and anyone interested in the development and applications of positioning theory.

This synthesis will be of interest to both administrative and technical personnel in departments of transportation (DOTs), especially in the areas of surveying, mapping, transportation planning, environmental impact assessment, design, construction control, maintenance, operations, vehicle location, and other functions that require accurate location data. This report will be useful for intermodal transportation analyses and for measurement and positioning data for inventories and geographic information systems (GIS). It can also be useful to suppliers and developers of Global Positioning System (GPS) equipment. This report of the Transportation Research Board presents a description of GPS, the major components, basic geodesy principles, how GPS functions, and how it can be applicable to the data and analysis requirements of transportation agencies. The anticipated cost effectiveness of GPS in terms of personnel, equipment, and time as related to the improved accuracies to be derived from GPS applications are described. Current and more advanced applications of GPS by DOTs to different transportation modes are presented. The report also includes a glossary of terms and a listing of GPS information sources.

E-BOOK EXCERPT

This book proposes a socio-pragmatic exploration of the discursive practices used to construe and dynamically negotiate positions in news interviews. It starts with a discursive interpretation of 'positioning', 'role' and 'challenge', puts forward the relevance of a distinction between social and interactional roles, demonstrates how challenges bring to the fore the relevant roles and role-components of the participants, and shows that in news interviews speakers constantly position and re-position themselves and each other through discourse.The discussion draws on an empirical fine-grained analysis of a 24-hour corpus of news interviews on Israeli television and a corpus of media references. The author postulates a discrepancy between interlocutors' normative expectations, which presuppose an asymmetrical division of labor, on the one hand, and real-life practice, which exhibits partial symmetry in speakers' selection of discourse patterns as well as reciprocity in the use of challenge strategies, on the other. Special attention is given to irony and terms of address, which are shown to act as the center-points of satellite challenge strategies, geared as an ensemble toward the co-construction of reciprocal positioning. The analysis of three case studies further sheds light on the negotiations of intertwined positionings in context.

E-BOOK EXCERPT

With the dissolution of the Warsaw Pact in Europe and the end of the Cold war, many of the long-standing political and ideological obstacles to minimizing force levels have been removed. The overriding issue is no longer who commands the greatest force divisions; rather, the immediate concern is to establish a minimum threshold to which nations may reduce their force levels and still retain a meaningful defense. In this book, Raj Gupta examines the geometry and positioning of conventional forces, especially at low force levels. Defense Positioning and Geometry uncovers certain spatial relationships that the defending commander must abide by for an effective defense and shows how they can be exploited to construct stable military balances and reduce forces to minimum levels. The author considers a number of important questions that must be addressed to establish a new order of low force levels, such as: What is the absolute minimum force density necessary for a coherent and robust defense? How deep can mutual cuts go without irreparably damaging defense capability and upsetting conventional stability? How should an arms control treaty that cuts deployed forces by 50 percent or more be structured? There is an urgency to develop general, universally applicable principles that dictate how conventional forces should be optimally structured. Such principles, once defined, are certainly applicable directly on the battlefieldโ€”in the civil wars in Yugoslavia and the Commonwealth of Independent States, and in the Iraqi invasion of Kuwait and the subsequent response. However, as the author demonstrates, these fundamental defense positioning rules can be employed more constructively in the task of dismantling the redundant firepower amassed by NATO, the Warsaw Pact countries, the Middle East, North and South Korea, and the China-India-Pakistan axis. The book shows how knowledge of the ideal force geometry at low force levels makes it possible to determine the arms control regimes necessary to fill any holes exposed by deep cuts.
