How does your cell phone know where you are right now? How is our planet changing due to geodynamic processes and ongoing climate change? How can these changes be precisely measured from space in order to obtain reliable information about the melting of ice sheets or the threat to coastal regions from rising sea levels? This popular science book provides answers to these and many other socially relevant questions. It is aimed at interested nonprofessionals who want to learn more about our fascinating planet, but also at experts in natural sciences. You are taken on an exciting journey through time from the first surveys in ancient times to the satellite era, which is providing us with a global view of our home planet. Illustrative examples demonstrate how deeply global positioning and navigation with satellites pervade our daily life, and what fundamental contributions geodesy makes to understanding the Earth system and determining the effects of climate change.

With interview contributions by Günter Hein, Harald Lesch and Stefan Rahmstorf.
