Isi artikel
Perturbations to the orbital elements of satellite flying in Earth orbit occur because of many changes in thermospheric conditions. The changes in this region, particularly in density and wind, cause significant effect on satellite. These changes in density and wind affect the aerodynamic drag on satellite, and forced by processes that include solar activity in long and short term, gravity waves, tides, and geomagnetic storm. Aerodynamic drag acting on satellite is linearly dependent on atmospheric density and quadratically dependent on the difference between the satellite velocity and in-track wind.
