The work is devoted to a series of experiments on the study of the ionosphere simultaneously by methods of vertical and oblique sounding with the help of domestic Parus-A ionosondes in the frequency range from ~1 to 20 MHz. This is the so-called method of combined sounding of the ionosphere, in which simultaneous emission of signals by two ionosondes is performed, then the signals of oblique sounding are superimposed on the ionogram of the vertical one. Information is given about the deployed ionosphere network of Roshydromet equipped with such ionosondes. The network consists of 10 ionosonde stations located over the whole territory of Russia: from Kaliningrad to Petropavlovsk-Kamchatsky. Parus-A series ionosondes became the basis for re-equipment of ionospheric stations of Roshydromet. From 2010 to 2015, 12 units were made. Experiments on combined sounding of ionosphere were conducted on all radiotracks between Parus-A ionosondes: in central Russia, Siberia and the Far East, as well as on the Moscow-Salekhard radiotrack. The results of the combined sounding of the ionosphere are analyzed. An assumption on the possibility and expediency of remote verification of the ionosonde as a measuring instrument is made. Some prospects for the development of the experiments for the next generation of ionosondes are discussed.
