Geodetic reference systems 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 in the traceability chain. First, references of unprecedented accuracy are established for ground-based verification of spatio-geodetic methods such as Satellite Laser Ranging (SLR) or Global Navigation Satellite Systems (GNSS). Secondly, it is aimed to improve the dynamic measurement of reference points for SLR and VLBI telescopes, and the geometric link between space geodesy techniques. Innovative field tools and new analysis strategies are also being developed. In the frame of the project, INRIM has developed a novel method to measure air temperature needed to obtain accurate measurements of the geodetic bases.
