The aim is to study the impact of the weak geomagnetic disturbances on the density of H + ions during the medium solar activity period (2015-2016). The methods of the study are the following: remote incoherent scattering technique, methods of statistical radio physics, statistical analysis of the results, and geophysical analysis of the observational results. Description of the developed techniques for analyzing of experimental data obtained using incoherent scatter radar is presented. The impact of changes in geomagnetic activity on the fraction of hydrogen ions in the topside ionosphere during the periods close to the autumnal equinox of 2015 and summer solstice 2016 are described. Hypothesis about the indirect impact (though the changes in the velocity of thermospheric winds) of the weak changes in the geomagnetic activity on the fraction of hydrogen ions is proposed, verified, and validated . The results can be used for improving of the quality of modern models of ion composition in the ionosphere and for improving of the plasmaspheric models. The use of the results may lead to a reduction of errors of estimates of the coordinates of objects when satellite positioning systems (GPS, Galileo) are used.
