摘要

Space debris long-term orbit propagation is one of thernmain problems for the space debris environment models.rnThe evolution of space debris in low Earth orbit (LEO)rnis determined by a complex interplay of differentrnperturbations. The aim of this paper is to investigate thernlong-term effects of the most dominating perturbations:rnEarth geopotential effects, atmospheric drag, luni-solarrnperturbations and solar radiation pressure. Thernatmospheric drag is the major non-gravitationalrnperturbation in LEO. This article provides an averagernmethod of numerical integration on one revolution forrnrotating and stationary atmosphere, and then one canrnmake use of various atmospheric densities to calculaternthe orbital evolution. Using this method, we havernanalyzed the effects of rotating and stationaryrnatmospheric drag perturbation on orbital lifetime. Thernresults show the effects of solar activity andrngeomagnetic index on orbital evolution are obvious. Thernlifetime difference in rotating atmosphere is mostlyrndepending on inclinations of space debris.
