Space-Time Reference Systems for Monitoring Global Change and for Precise Navigation in Space
The objective of Research Unit 1503 is to develop integrative methods and procedures for a consistent definition and realisation of reference systems on Earth and in space. In an environment of ever increasing observing capabilities as well as of social and scientific needs, a framework of reference systems will be produced which are linked consistently with an appropriate level of accuracy to guarantee a solid basis for measuring geometric effects of Global Change and for high-precision navigation near Earth and in deep space. The contributions of various groups active in geodetic, astronomical and space sciences enable a comprehensive interdisciplinary treatment of reference systems.
