Numerical investigation of the orbit of Interball-1

Research output: Contribution to journalArticle


We investigated the motion of the Earth's artificial satellite Interball-1 by using a method suitable for the computation of large eccentricity orbits. Though the measured and the computed orbital elements differ from each other within the measured error bound, we found a slight tendency for secular decreasing in the semi-major axis, caused probably by electromagnetic drag. We analysed the dominant role of the Moon in the variations of the orbital eccentricity, leading to zero perigee height and the end of the lifetime of the satellite.
