One of the goals of the EC Horizon 2020 project JUMPING JIVE was to establish a geodetic path at the European VLBI Network (EVN) correlator at JIVE (SFXC). This was successfully implemented in 2019, and since then we have conducted two EVN geodetic-type experiments at K-band, EC065 and EC076, taking advantage of this new capability. The two experiments exercised all aspects of the new geodetic path, from correlation to data export in MK4 format and post-processing, using standard geodetic analysis tools. These were carried out in 2018 and 2020, and involved both geodetic and non-geodetic EVN antennas, including Sardinia, Torun, and the Jodrell Mark2 telescope, along with the e-MERLIN outstations and KVN (Korean VLBI Network) telescopes. The main goal is to obtain precise geodetic coordinates for these antennas. The project will also consider the results from similar experiments conducted previously, going back to 2000, to allow for the estimation of the station velocity. This contribution presents the current state of the project.
