Modern HF digisonde DPS-4 D (Digisonde Portable Sounder), which is in operation at the
Pruhonice observatory of the Institute of Atmospheric Physics, Prague (IAP) from 2004, enables
us to carry out ionospheric drifts measurements. Using standard mode of automatic drift
(autodrift mode) measurements the velocity of the F region drifts is usually determined in the
vicinity of the peak of the electron density profile (N(h) profile). Since 2005 we are also
measuring ionospheric drifts at the heights of the ionospheric E region (within the altitudinal
interval of 95-145 km). Here we present the analysis of the plasma drifts of two different
ionospheric regions observed under quiet time and under moderate-to-intense ionospheric storm
conditions during the period 2005-2016. Storm effects on the electron density distribution are
also presented.
