Abstract
The motion of an uncontrolled spacecraft around its center of mass, the restoring aerodynamic moment of the spacecraft being described by an odd Fourier series in the angle of attack with the three first harmonics. The cases are investigated in which the character of motion changes during the reentry process: the rotational motion is transformed into the oscillatory one, and the oscillatory motion is transformed “by jumping” into the oscillatory motion with different amplitude characteristics. It is shown that transient modes of angular motion at the initial section of the trajectory may have essential influence on the movement of the centre of mass of the spacecraft and, as a result, cause deviation from the estimated trajectory.
