Attitude dynamics modeling of a dual-spin nanosatellite with an elastic longitudinal axis

The paper considers the dynamics of a dual-spin nanosatellite with an internal rotor placed into movable module on elastic connections. The nanosatellite consists of two modules - a carrier body and a mobile module with a rapidly rotating internal rotor, which classifies the nanosatellite as a dual-spin spacecraft. The movable module is connected to the main module by flexible rods. Changing the length of these rods makes it possible to carry out angular displacements of the nanosatellite and, therefore, to control the attitude dynamics of the nanosatellite.
