A GPS

Author: Frank Stephen Tromp Van Diggelen
Publisher: Artech House
ISBN: 9781596933750
Release Date: 2009
Genre: GNSS technology and applications series

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 you understand why GPS requires assistance in the first place. You 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, you learn how to design and analyze a high sensitivity GPS receiver and determine the achievable sensitivity. The book provides detailed worksheets that show how to compute, analyze, and improve the processing gain from the input signal at the antenna to the signal after the correlators. These worksheets are used in the book to generate families of curves that completely characterize receiver sensitivity, parameterized in terms of front end noise figure, coherent and noncoherent integration times. From this work a law of achievable sensitivity is derived and explained in the book.

Release Date: 2007-03-05
Genre: Science

An updated guide to GNSS and INS, and solutions to real-world GPS/INS problems with Kalman filtering Written by recognized authorities in the field, this second edition of a landmark work provides engineers, computer scientists, and others with a working familiarity with the theory and contemporary applications of Global Navigation Satellite Systems (GNSS), Inertial Navigational Systems (INS), and Kalman filters. Throughout, the focus is on solving real-world problems, with an emphasis on the effective use of state-of-the-art integration techniques for those systems, especially the application of Kalman filtering. To that end, the authors explore the various subtleties, common failures, and inherent limitations of the theory as it applies to real-world situations, and provide numerous detailed application examples and practice problems, including GNSS-aided INS, modeling of gyros and accelerometers, and SBAS and GBAS. Drawing upon their many years of experience with GNSS, INS, and the Kalman filter, the authors present numerous design and implementation techniques not found in other professional references. This Second Edition has been updated to include: GNSS signal integrity with SBAS Mitigation of multipath, including results Ionospheric delay estimation with Kalman filters New MATLAB programs for satellite position determination using almanac and ephemeris data and ionospheric delay calculations from single and dual frequency data New algorithms for GEO with L1 /L5 frequencies and clock steering Implementation of mechanization equations in numerically stable algorithms To enhance comprehension of the subjects covered, the authors have included software in MATLAB, demonstrating the working of the GNSS, INS, and filter algorithms. In addition to showing the Kalman filter in action, the software also demonstrates various practical aspects of finite word length arithmetic and the need for alternative algorithms to preserve result accuracy.

Erdmessung und Satellitengeod sie

Author: Reiner Rummel
Publisher: Springer-Verlag
ISBN: 9783662471005
Release Date: 2017-08-18
Genre: Science

Das Handbuch der Geodäsie ist ein hochwertiges, wissenschaftlich fundiertes Werk über die Geodäsie unserer Zeit und bietet anhand von in sechs Bänden zusammengestellten Einzelthemen ein repräsentatives Gesamtbild des Fachgebiets. Satelliten führten zu einer Revolution in der Geodäsie. Erst mit Hilfe von Satelliten wurde die Erdmessung tatsächlich global und dreidimensional. Ozeane und Eisschilde stellen keine Hindernisse mehr dar, sie lassen sich heute mit gleicher Präzision vermessen wie die Kontinente. Verfeinerungen resultieren aus der Kombination von Raumverfahren mit terrestrischen Messmethoden. Damit gelingt es der Erdmessung, fundamentale Beiträge zum Verständnis des Erdsystems und des Klimawandels zu liefern. Voraussetzung für diese Entwicklung sind sehr moderne Messverfahren und Auswertemethoden und deren extrem genaue Verknüpfung in einem globalen erd- und raumfesten Referenzsystem. Im Band Erdmessung und Satellitengeodäsie werden exemplarisch die historischen Wurzeln, methodischen Grundlagen, verwendeten Messverfahren sowie die Forschungstrends vorgestellt.
