title: Network of Stations of the Crimean Geodynamic Test Area: Local Ties Variations and Their Comparison with the Values Obtained in the ITRF2020 Reference Frame
abstract: The Simeiz–Katzively Crimean geodynamic test area is one of the unique site in the world, in which several space geodesy observation stations are located, namely, RT-22 radio telescope (CRIMEA, CDP no. 7332), satellite laser ranging (SLR) stations 1873 Simeiz and 1893 Katzively, permanent GNSS stations CRAO and KTVL, and the marker of mobile SLR station 7561 Simeiz. Four local survey geodetic campaigns and five GNSS campaigns were performed to determine local ties between space geodesy stations
