Continuous observation possibility of thin extra plasma density walls in the high-latitude ionosphere from the "ARKTIKA-M" satellites
New structure element of the Arctic ionosphere - quasivertical walls of extra p lasma density - was detected from the data of topside sounding. The importance of studying this phenomenon for geophysics and the practice of radio waves propagation in high latitudes was noted. For its study, it was proposed to use «ARKTIKA-M» hydrometeorological space complex with an onboard ionosonde. The observation and analysis possibility of all life cycle phases of this ionospheric disturbance is shown.
