National geomagnetic observatory Budkov is located near Budkov village in region Prachatice. Since 1996 observatory meets all international requirements, standards and is certified INTERMAGNET observatory.

Variations of geomagnetic field are recorded with the modern three-axis fluxgate sensor Narod, whose signal is sampled and data are stored directly. This allowing to obtain digital data in real time. Digital data are recorded together with historical analog data (system Bobrov).

The acquisition system in Budkov is capable to record variations of Geomagnetic field already in one second intervals with an accuracy of 0.1 [nT], but standart continuous registration is working in 1-minute intervals at present.

Continuous measurement is complemented by an absolute measurement of the geomagnetic field every 10 days. The absolute measurement is realized with non-ferromagnetic theodolite CARL-ZEISS, which is extended by uniaxial fluxgate sensor BARTINGTON (Flux D & I).

Traditional research is transformed into a modern way of data acquisition, and has become one of the pillars of forecasting of geomagnetic activity. The data are supplied to the World Data Center in Boulder (USA) and to international center INTERMAGNET in Edinburgh (Scotland).
