The European VLBI Network (EVN) has been used in geodesy mode at K band for the purpose of determining the geodetic positions of non-geodetic EVN telescopes (i.e. without S/X receivers). The work was initiated within the context of the EC-funded JUMPING JIVE project (2017-2021). For this purpose, a number of high-quality sources spread over the sky and belonging to the third realization of the International Celestial Reference Frame (ICRF3) have been targeted. The data have allowed us to estimate the positions of the non-geodetic EVN telescopes in the ITRF2020, the terrestrial reference frame currently in use, with cm level precision. Additionally, high-resolution images of the observed ICRF3 sources have been derived. A specificity of the images is that they show increased resolution compared to those derived from the Very Long Baseline Array. The presentation will detail these results.
