Ground-Based Wireless Positioning

Positioning in Wireless Communications Systems explains the principal differences and similarities of wireless communications systems and navigation systems. It discusses scenarios which are critical for dedicated navigation systems such as the Global Positioning System (GPS) and which motivate the use of positioning based on terrestrial wireless communication systems. The book introduces approaches for determination of parameters which are dependent on the position of the mobile terminal and also discusses iterative algorithms to estimate and track the position of the mobile terminal. Models for radio propagation and user mobility are important for performance investigations and assessments using computer simulations. Thus, channel and mobility models are explored, especially focussing on critical navigation environments like urban or indoor scenarios. Positioning in Wireless Communications Systems examines advanced algorithms such as hybrid data fusion of satellite navigation and positioning with wireless communications and cooperative positioning among mobile terminals.. The performance of the discussed positioning techniques are explored on the basis of already existing and operable terrestrial wireless communication systems such as GSM, UMTS, or LTE and it is shown how positioning issues are fixed in respective standards. Written by industry experts working at the cutting edge of technological development, the authors are well placed to give an excellent view on this topic, enabling in-depth coverage of current developments. Key features • Unique in its approach to dealing with a heterogeneous system approach, different cell structures and signal proposals for future communications systems • Covers hybrid positioning investigating how GNSS and wireless communications positioning complement each other • Applications and exploitation of positioning information are discussed to show the benefits of including this information in several parts of a wireless communications system

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.

Nonprofit Strategic Positioning: Decide Where to Be, Plan What to Do is the first nonprofit-oriented book to describe strategic positioning as an alternative to traditional strategic planning. Even in the nonprofit sector, strategic planning is becoming discredited as a formulaic, go-nowhere exercise. This book will take the reader on a stimulating journey through nonprofit strategy development and implementation. The book is timely because the nonprofit sector has reached a turning point where the need to be more business-like is undeniable, and the continuing retreat of the public sector has left even wider gaps in services that nonprofits will be asked to fill. Nonprofit Strategic Positioning: Decide Where to Be, Plan What to Do offers a fresh new way for nonprofits to meet the challenges of the 21st century.

Written by a researcher at the forefront of the field, this first comprehensive account of magnetoseismology conveys the physics behind these movements and waves, and explains how to detect and investigate them. Along the way, it describes the principles as applied to remote sensing of near-Earth space and related remote sensing techniques, while also comparing and intercalibrating magnetoseismology with other techniques. The example applications include advanced data analysis techniques that may find wider used in areas ranging from geophysics to medical imaging, and remote sensing using radar systems that are of relevance to defense surveillance systems. As a result, the book not only reviews the status quo, but also anticipates new developments. With many figures and illustrations, some in full color, plus additional computational codes for analysis and evaluation. Aimed at graduate readers, the text assumes knowledge of electromagnetism and physical processes at degree level, but introductory chapters will provide an overview of the relevant plasma physics and magnetospheric physics. The book will thus be of interest to entry-level and established researchers in physics of the Earth's magnetosphere and ionosphere, as well as to students, academics and scientifically literate laypersons with an interest in understanding space weather processes and how these relate to the dynamic behavior of near-Earth space.
