| | Summary: |
| | One of the main challenges in Geodesy is the definition and realization of stable Global Geodetic Reference Systems with geometric and physical characteristics which is necessary for applications in science and society. For that reason, International Association of Geodesy (IAG) has established the Global Geodetic Observing System (GGOS), which is integrating the three basic components: geometry, the earth rotation and gravity. The global reference frame in the GGOS is a realization of the International Terrestrial Reference System (ITRS), a world spatial reference system co-rotating with the Earth in its diurnal motion in the space. Global Geodetic Reference Systems are necessary for determining the position on Earth and in space, as well as the precise measurement of changes caused by geodynamic and climatic processes. They represent a unified basis for geospatial data, positioning, satellite navigation and other applications. The backbone of this integration is the existing global ground network, based on analysis of data from key space geodetic techniques VLBI, SLR, GNSS and DORIS. |
