Ten GNSS stations were established and its coordinates were computed in ITRF and ETRF coordinates systems. The Web-site of the GNSS network of West regions was updated. The method for determination of transformation parameters between ETRF and USC2000, SC42 and SC63 was improved by the posterior optimization of measurements. The optimal method for determination of quasigeoid parameters for Vinnitska and Odesska regions by the combination of GNSS leveling on the leveling benchmarks together with satellite gravimetry information.  Product Description popup.authors Brusak Ivan V Vivat Anatolii Yo Hlotov Volodymyr M Dzhuman Bohdan B Sidorov Ihor S Savchin Ihor R Smirnova Olha M Tserklevych Anatoly L popup.nrat_date 2022-03-09 Close
