Taschenbuch. Condition: Neu. Druck auf Anfrage Neuware - Printed after ordering - The high accuracy of modern astronomical spatial-temporal reference systems has made them considerably complex. This book offers a comprehensive overview of such systems. It begins with a discussion of 'The Problem of Time', including recent developments in the art of clock making (e.g., optical clocks) and various time scales. The authors address the definitions and realization of spatial coordinates by reference to remote celestial objects such as quasars. After an extensive treatment of classical equinox-based coordinates, new paradigms for setting up a celestial reference system are introduced that no longer refer to the translational and rotational motion of the Earth. The role of relativity in the definition and realization of such systems is clarified.The topics presented in this book are complemented by exercises (with solutions). The authors offer a series of files, written in Maple, a standard computer algebra system, to help readers get a feel for the various models and orders of magnitude. Beyond astrometry, the main fields of application of high-precision astronomical spatial-temporal reference systems and frames are navigation (GPS, interplanetary spacecraft navigation) and global geodynamics, which provide a high-precision Celestial Reference System and its link to any terrestrial spatial-temporal reference system. Mankind's urgent environmental questions can only be answered in the context of appropriate reference systems in which both aspects, space and time, are realized with a sufficiently high level of accuracy. This book addresses all those interested in high-precision reference systems and the various techniques (GPS, Very Long Baseline Interferometry, Satellite Laser Ranging, Lunar Laser Ranging) necessary for their realization, including the production and dissemination of time signals.

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Täglich und in immer größerer Zahl werden Kleinplaneten neu entdeckt. Angesichts des wachsenden Datenaufkommens ist die Realisierung einer automatischen Vermessung ihrer Positionen erstrebenswert. Moderne Methoden der digitalen Aufnahme- und auch der Computertechnik erlauben heute die unmittelbare Verarbeitung der am Teleskop gewonnenen Bilder. Doch wie lässt sich ein vollautomatischer Messprozess für Kleinplaneten-Positionen realisieren Welche Methoden garantieren dabei gleichzeitig höchste Präzision sowie Allgemeingültigkeit der Lösung Der Autor Ralf Langhans stellt in seinem Buch Verfahren vor, die alle Aspekte der Kleinplaneten-Astrometrie von der Gewinnung der Bildkoordinaten bis hin zu speziellen Fragen, wie z.B. der differentiellen chromatischen Refraktion, beleuchten. Praxisnah werden zudem Ansätze zur programmiertechnischen Umsetzung aufgezeigt und Vergleiche mit anderen Softwarelösungen hergestellt. Das Buch richtet sich gleichermaßen an Wissenschaftler und interessierte Amateurastronomen, die auf dem Gebiet der Positionsbestimmung von Kleinplaneten tätig sind.
