We propose to measure the positions of 6 non-geodetic EVN telescopes by carrying out a non-standard geodetic-type experiment at 22 GHz. This repeats an experiment that we originally carried out at 5 GHz in November 2000 (TP001). Observing at higher frequency will be largely of benefit for reducing systematic errors caused by the ionosphere which were dominant in TP001 due to the relatively low observing frequency of 5 GHz. Knowledge of all EVN telescope positions is mandatory for phase referencing observations which require an accurate VLBI geometrical model to perform well. This experiment will also allow us to determine the velocities of Jodrell Bank and Torun by comparing the positions at the current epoch with those in 2000. The proposal is also meant to test and validate the new geodetic capability of the JIVE correlator which is developed as part of the JUMPING JIVE project.

This data is part of the archive of VLBI data maintained by JIVE on behalf of the EVN, a network of radio telescopes located primarily in Europe and Asia, with additional antennas in South Africa. The EVN archive itself has the DOI https://doi.org/10.17616/R3Z197
