Ionosphere Reaction to the Impact of Jet Engines According to GEONET Network of GPS Stations

The present study evaluating the use of dense GEONET Japanese network to detect ionospheric response to the weak impact of the jet engines of the spacecraft "Progress" using the example of May 4, 2006. Analysis of the TEC series shows that a negative disturbance occurs in the affected area. The amplitude of the disturbance was about 0.05 TECU. The amplitude of the disturbance decreases with distance from the area of impact, and at a distance of 60–70 kilometers becomes less than the amplitude of the background variations. The duration of the observed disturbance does not exceed 8 minutes.
