Large-scale dimensional measurements for geodesy (GeoMetre)

 

Logo of EMPIR

 

Geodetic reference frames form the backbone of all georeferencing services. Observations like sea level monitoring require an uncertainty of 1 mm or better when comparing global data, significantly below the current scale uncertainty of about 4 mm at the Earth surface. This project focuses on two critical points in the complex traceability chain. Firstly, references of unprecedented accuracy for the Earth-bound verification of space-geodetic methods like Satellite Laser Ranging (SLR) or Global Navigation Satellite Systems (GNSS) are established. Secondly, the surveying capabilities for the geometric tie of co-located space-geodetic observations are systematically improved. Innovative field instrumentation and novel analysis strategies will thus be developed.
