Studies of Satellite Position Measurements of LEO CubeSat to Identify the Motion Mode Relative to Its Center of Mass

This paper addresses the possibility of reconstructing motion relative to center mass a low Earth orbit (LEO) nanosatellite CubeSat 3U standard using satellite position measurements (Two-Line Element Set (TLE)). kind task needs be performed in case where it is not possible establish radio communication with after launched into orbit. Therefore, important for developers develop some understanding what going on order able analyze current situation deployment. The study was carried out example aerodynamically stabilized SamSat-218D developed by professors and students Samara National Research University. near-circular an average altitude 486 km April 2016 during first launch campaign from Vostochny cosmodrome. Knowledge aerodynamics allows estimating nature its ballistic coefficient changes, evaluated use measurements. analysis showed that spatial rotation angular velocity more than two degree per second had 2 March 2022, when entered atmosphere destroyed.
