Abstract

The satellite moving on a very low Earth orbit (VLEO) is considered. The satellite is subjected to the influence of the gravitational field, aerodynamic drag, magnetic control torque, and different disturbing factors. Aerodynamic torque is the main restoring torque. Magnetic attitude control system provides the angular velocity damping and the rotation around the longitudinal axis. Brief models description is provided and numerical simulation results are presented including the estimation of the microaccelerations. [ABSTRACT FROM AUTHOR]

Abstract

The commented paper discusses the attitude dynamics representation using quaternions. The main idea of the paper is to eliminate angular velocity from the dynamics equations. The obtained equations are interesting. However, all applications presented in the discussed paper have plain errors in the equations derivations. This affects the main results and conclusions of the paper, which require significant corrections. • Errors in commented paper are outlined. • Quaternion dynamics equations application for the attitude control is discussed. • Control singularity is shown.
