These proceedings include selected papers from the International Review Workshop on Satellite Altimetry Cal/Val Activities and Applications, held in Chania, Crete, Greece, on 23-26 April 2018. Organised in the context of the European Space Agency Project “Fiducial Reference Measurements for Altimetry” the workshop was cosponsored by the International Association of Geodesy (in particular by the IAG Commission 2, Gravity Field), the European Space Agency, the European Union (the Copernicus Programme), the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), Space Geomatica P.C., and the Municipality of Chania.

The workshop presented the latest research in the field of satellite altimetry calibration and altimetry applications for monitoring ocean changes and improving Earth observation in an objective, continuous, homogeneous and reliable manner, free of errors and biases. Further, it supported long-term monitoring of climate change by providing abetter understanding of environmental changes in the world''s oceans, terrestrial surface waters, and Arctic and Antarctic Regions. The outcome was the creation of a scientific roadmap with procedures, protocols, guidelines, and best practices to help international groups working on satellite altimetry to establish SI (Système International d''Unités) traceability of their measurements, results and data products.

The fifth edition of this textbook has been completely revised and significantly extended in order to reflect the revolution of geodetic technologies, methods and applications during the last decade. The Global Geodetic Observing System established by the IAG utilizes a variety of techniques to determine the geometric shape of the earth and its kinematics, the variations of earth rotation, and the earth’s gravity field. The societal importance of geodetic products was highlighted by the UN resolution on the Global Geodetic Reference Frame. In this context, both space and terrestrial techniques play a fundamental role. Recent space missions are monitoring climate-relevant processes such as mass transport in the Earth system and sea level changes. The analysis of the time variation of the geodetic products provides the link to neighboring geosciences and contributes to proper modelling of geodynamic processes. New satellite mission concepts and novel technologies such as quantum gravimetry and optical clocks show great potential to further improve the geodetic observing system in the future. The book especially addresses graduate students in the fields of geodesy, geophysics, surveying engineering, geomatics, and space navigation. It should also serve as a reference for geoscientists and engineers facing geodetic problems in their professional work. The book follows the principal directions of geodesy, providing the theoretical background as well as the principles of measurement and evaluation methods, which is enriched with numerous figures. An extensive reference list supports further studies.

Woher weiß Ihr Handy, wo Sie gerade unterwegs sind? Wie verändert sich unser Planet aufgrund von geodynamischen Prozessen und dem fortschreitenden Klimawandel? Wie können diese Veränderungen präzise aus dem Weltraum vermessen werden, um verlässliche Aussagen etwa über das Abschmelzen der Eisschilde oder die Bedrohung von Küstenregionen durch den steigenden Meeresspiegel zu erhalten? Das vorliegende Sachbuch gibt Antworten auf diese gesellschaftlich relevanten Fragen. Es richtet sich an interessierte Laien, die mehr über unseren faszinierenden Planeten erfahren wollen, aber auch an Fachexperten naturwissenschaftlicher Disziplinen. Sie werden mitgenommen auf eine spannende Zeitreise von den ersten Vermessungen in der Antike bis in das Zeitalter der Satelliten, die uns die weltweite Bestimmung von extrem genauen Positionen und eine globale Sicht auf unseren Heimatplaneten ermöglichen. Anhand anschaulicher Beispiele wird vermittelt, wie tief die globale Positionierung und Navigation mit Satelliten unseren Alltag durchdrungen haben, und welche fundamentalen Beiträge die Geodäsie als die Wissenschaft von der Vermessung der Erde zum Verständnis des Erdsystems und zur Bestimmung der Auswirkungen des Klimawandels liefert.
