| Summary: | Using GPS dual-frequency observations collected by continuously operating
GPS tracking stations in China, superimposed disturbances caused by the
integrated action of spacecraft's physical effect and chemical effect on
ionosphere during the launches of the spacecrafts Tiangong-1 and Shenzhou-8
in China were firstly determined. The results show that the superimposed
disturbance was composed of remarkable ionospheric waves and significant
ionospheric depletion emerged after both launches. Meanwhile, we found
for the first time that the ionospheric waves were made up of two periods of
wave by wavelet analysis. The first period of ∼ 4 min shows
one event in the near stations and two sub-events in the few far stations.
The second period of ∼ 9 min shows only one event in all the
observed stations. Finally, the time characteristics for ionospheric waves
and depletions were examined. |
