Formation, development and the current state of geomagnetic observatories of Ukraine

The development path of geomagnetic observatories of Ukraine from their foundation to the present is shown. The process of modernization of these observatories and their current state is described. The first digital magnetovariation stations at the geomagnetic observatories «Lviv» and «Odesa» were installed thanks to close cooperation with the Institute of Geophysics of the Polish Academy of Sciences. Today, the main software for preparing data in the INTERMAGNET formats is the software developed by Polish colleagues.
