Аннотация:The article presents the justification and results of the author’s activity increating means of modeling the motion of satellites of giant planets andsatellites of asteroids. The necessity of this activity is due to the possibilityof using planetary satellites as the most suitable places for landing spacecraftand expanding the human habitat. Therefore, it is necessary to calculate theposition of satellites in space with the most excellent possible accuracy toget there with minor energy costs. It could be done by developing satellitemotion models. Such models, also called ephemeris, are the result of studyingthe dynamics of these bodies since they are based on all our knowledge,including all available observations.The study of the dynamics of satellites byconstructing models of motion is also a means of ensuring the familiarizationof the solar system and the extraction of new fundamental knowledge. Theresult of the work was a database of observations of satellites of planets and aserver of ephemeris of satellites. All are available to any user via the internet.
