Abstract
Apply of the method of time-frequency
analysis allows to reveal the detailed structure of the
manifestations of the influence of the state space weather
on the upper atmosphere of the Earth. Sensitive indicators
of such changes are low-orbit satellites. The dynamics of
drag of nineteen low–orbit satellites was viewed. The
study period includes phases of declining and a long
minimum of 23rd solar cycle, phases of rise and maximum
of 24th solar cycle. In dynamic of inhibition of all the
analyzed satellite pronounced regular inhibition effects
with extended periods of 2 – 6 years and short-period
effects with periods less than one year. In the satellites:
00063, 00165, 25064, 00932 and 00746 – detected periods
with trend from 25 – 28 days to 1 – 1.7 months.
