“…The dynamic evolution of space debris in the vicinity of the area of motion of satellites of global navigation systems is studied based on numerical simulation. The orbital evolution of space objects is modeled in ''Numerical Model of the Motion of an Artificial Satellites'' [12,21] developed at the Tomsk State University. The model of perturbing forces takes into account the major perturbing factors: • the gravitational field of the Earth (EGM96 model [22], harmonics up to the 29th order and degree, inclusive, for the correct description of the movement of objects in eccentric orbits and before re-entering), • the gravitation of the Moon and the Sun,…”

Orbital plane flips, a transition from prograde to retrograde motion or vice versa, is a phenomenon due to solar radiation pressure that is investigated. We consider initial near-circular orbits with different inclinations, including the vicinity of orbits of the GNSS satellites, GEO, geosynchronous orbits, and super-GEO region. Dynamical evolution of orbits is studied from a numerical simulation. Initial conditions for the objects are chosen in the GNSS orbit regions (GLONASS, GPS, BeiDou, Galileo) as well as 450-1100 km above to nominal semi-major axes of the navigation orbits, and in the vicinity of GEO, geosynchronous orbits, and super-GEO region. Initial data correspond to nearly circular orbits with the eccentricity 0.001. The initial inclination is varied from 55 • to 64.8 • . Initial values of longitude of ascending node are varied from 0 • to 350 • . High area-to-mass ratios are considered, at which orbital plane flips occur. Dynamical evolution covers periods of 24 and 240 years. The maximum inclination of the orbit is achieved when the longitude of the pericenter is sun-synchronous. Flips are possible only for objects with the area-to-mass ratio equal or more than 16 m 2 /kg (the radiation pressure coefficient is 1.44). The flips are caused precisely by solar radiation pressure. The Lidov-Kozai effect is suppressed by solar radiation pressure perturbations, affecting high area-to-mass ratio objects due to a secondary apsidal-nodal secular resonance.
