This book was released on 2014 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Der Inhalt dieses Buches gibt die Ergebnisse der Arbeit im Rahmen meiner Dissertation wieder. Zum ersten Mal wurde im Rahmen der vorliegenden Forschungsarbeit die Funktionalität eines GNSS-Empfängers mit der Information eines Zeitsignals kombiniert. Die vorliegende Arbeit verwendet dazu die Eigenheiten des DCF77-Signals um eine hocheffiziente kombinierte Signalverarbeitung zu ermöglichen. Die Kombination von Zeitsynchronisations- und Navigationssignalen eliminiert den größten Nachteil klassischer Assisted-Empfängerarchitekturen, den massiven Einsatz von Rechenleistung in der digitalen Signalverarbeitung. Trotzdem bleiben die Vorteile der bekannten Architekturen, eine kurze Time-to-First-Fix bei geringem Stromverbrauch erhalten. Aufbauend auf der bekannten Architektur des Single-Shot-Empfängers erlaubt die Erweiterung um die Zeitinformation zusammen mit der bereits bekannten Navigationsnachricht und der geschätzten Position eine Vorausberechnung der zu erwartenden Satellitensignale. Die Vorausberechnung der Satellitensignale resultiert in einer Reduktion des Suchfensters für die Kodephase der Satellitensignale. Neben einer Beschreibung der Grundlagen der Satellitennavigation und der Übertragung von Zeitsignalen über Langwelle, werden in diesem Buch die entwickelte Architektur vorgestellt. Außerdem sind die Ergebnisse einer komplexen Systemsimulation, Teil dieses Buches.

Book excerpt: This Handbook presents a complete and rigorous overview of the fundamentals, methods and applications of the multidisciplinary field of Global Navigation Satellite Systems (GNSS), providing an exhaustive, one-stop reference work and a state-of-the-art description of GNSS as a key technology for science and society at large. All global and regional satellite navigation systems, both those currently in operation and those under development (GPS, GLONASS, Galileo, BeiDou, QZSS, IRNSS/NAVIC, SBAS), are examined in detail. The functional principles of receivers and antennas, as well as the advanced algorithms and models for GNSS parameter estimation, are rigorously discussed. The book covers the broad and diverse range of land, marine, air and space applications, from everyday GNSS to high-precision scientific applications and provides detailed descriptions of the most widely used GNSS format standards, covering receiver formats as well as IGS product and meta-data formats. The full coverage of the field of GNSS is presented in seven parts, from its fundamentals, through the treatment of global and regional navigation satellite systems, of receivers and antennas, and of algorithms and models, up to the broad and diverse range of applications in the areas of positioning and navigation, surveying, geodesy and geodynamics, and remote sensing and timing.

Download or read book Positioning in Wireless Communications Systems written by Stephan Sand and published by John Wiley & Sons. This book was released on 2014-02-18 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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
