© 2019 IEEE. The paper deals with the problems of the mid-latitude MSTIDs detection with low intensity of electron density, ΔN/N, using the GNSS transionospheric sounding method. To collect data, a dense network of GNSS receivers located on the territory of the Russian Federation (more than 150 pcs.) has been used. On the basis of the obtained experimental data, the selectivity of the method of transionospheric sounding towards the MSTIDs, depending on the satellite-receiver line-of-sight orientation, is shown. Thus, the use of two-dimensional maps of TEC perturbations allowed to simultaneously observe the MSTIDs signatures using the satellites R03, G18 (which have similar geometric conditions of observation) and not observe them using the satellite R18. Accounting the mutual layout of the satellite-receiver lines-of-sight and phase front of the wave made it possible to form a method for observing the low-intensity midlatitude MSTID.
