GGOS a Masterpiece of Geodesy

GGOS is like an orchestra playing a masterpiece of music. The composer is the System Earth. The music sheets are the signals caused by changes of the System Earth. The musical instruments are the geodetic sensors detecting the signals of Earth…

Geodesy: The Cornerstone for a Comprehensive Observation of the System Earth

Geodesy provides the foundation on which all Earth observation systems are built. In this function, Geodesy is essential for Earth observation just like the foundation and frame of a house are necessary to keep it stable over time. Geodesy continuously…

A Modern Network of Geodetic Sensors for the Observation of the Earth

The wide-range of signals emitted by changes in the System Earth are not detectable by a single measurement technique. While positioning techniques (VLBI, SLR, GNSS, DORIS) have demonstrated be an efficient tool to determine the kinematics of…

High and Consistent Performance through Standardisation

Different geodetic sensors register different System Earth signals. To produce an integral and global picture of this System, all geodetic observing techniques and analysis methods should be brought together consistently. The same standards,…
