Geodetic reference frames form the backbone of all georeferencing services. In order to compare global measurement data for observations such as sea level monitoring an uncertainty of 1 mm or better is required, significantly below the current capability of 4 mm. This project focuses on two critical points within what is a 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.
Project duration: 06/2019 - 11/2022
