We consider a gravity-oriented rigid body on a circular Keplerian orbit in a central
gravitational field. The motion of the body is affected by a perturbation torque given by a …

This work describes the attitude determination and the gyros drift estimation using the
Extended Hю Filter for nonlinear systems. Such filter uses the Taylor series to approximate …

The objective of this paper is to analyze the stability of the rotational motion of a symmetrical
spacecraft, in a circular orbit. The equilibrium points and regions of stability are established …
