Secular variations of semimajor axis of debris particles near GEO due to solar radiation pressure

A study of long-time orbit variations of high satellite orbits due to solar radiation pressure was performed, as well as evolution of debris particle orbits near geosynchronous orbit. Debris particles are involved in all natural processes in the near vicinity of the Earth, including such as solar activity. Only the asymmetry of the scattering field is the cause of secular evolution of the orbit. Such radiation pressure leads debris particles on the geostationary orbit move along non-libration orbits instead to gather around the libration points. This proves the existence of a natural way to clean the geostationary orbit from a part of space debris fragments. We assume that a bent metallic sheet represents the debris particle. Obtained results showed that sufficient deviation of its semimajor axis occur.
