The main factor of changes of behavior of artificial satellites of the Earth on the orbit is the influence of aggregate of active processes on the Sun (so-called space weather) and their response in the near-Earth environment. The influence of heliogeoactivity on the dynamics of artificial satellites was investigated. The selected objects are the uncontrolled satellites, their elements of orbits are from the database of Ukrainian network of optical stations (УМОС). As a result a comprehensive research was established relationship between the characteristics of solar activity, their response in the near-Earth environment and variations of periods P of the orbital motion of artifical satellites. These variations mainly denote changes in the density of Earth's atmosphere caused by a solar (index F10.7) and geomagnetic activity ( ΣKpindex). The correlation coefficients of P and F10.7(–0.77...–0.91) and of P and ΣKp (–0.67...–0.89) are the evidence of significant connection between them. The obtained results are good indicator of influence of helio- and geoactivity on the periods of the satellites.
