Stage 1: Investigations of geospace conditions above the Ukraine using HF Doppler sounding and radioscopy of the ionosphere by signals of GNSS transmitters popup.stage_title Head Zalizovski Andriy V., Доктор фізико-математичних наук Registration Date 22-02-2019 Organization Institute of Radio Astronomy of the NAS of Ukraine popup.description2  The regular coherent vertical sounding of the ionosphere (CFSI) over the Kharkiv region using the ionosonde of own production has been started. The use of median heighte-time diagrams of ionospheric parameters is proposed for a more complete representation of ionospheric behavior during the month. Measurements of travelling ionospheric disturbances were carried out and their parameters were obtained over the Kharkiv region using simultaneously three systems: a coherent ionosonde, a 3-position Doppler system, and radioscopy of the ionosphere by the signals of GNSS satellites. A scheme was developed and operating modes were calculated for the measuring campaign with Arecibo heating facility (Puerto Rico). Measurements in the ULF-UHF bands at the Low Frequency observatory as observatory of Subsatellite System for Ionospheric Measurements and in other locations, and the data presentation on the web-page of Department of Radiophysics of Geospace of IRA NASU were provided.
