<p>This paper investigates the feasibility of employing dry friction dampers for the attitude dynamics of microsatellites and nanosatellites during gravity-gradient stabilization in circular orbits. In this configuration, the gravitational dampers consist of rigid bodies with general inertia tensors, placed inside spherical capsules that rotate with dry friction within external rings fixed to the satellite’s main body. This rotational motion dissipates kinetic energy and angular momentum associated with attitude motion in the gravitational field; consequently, under the influence of central gravity forces, the satellite proceeds to a stable attitude position along its orbit. Classical gravitational dampers for satellites typically employ rigid bodies with spherical inertia tensors rotating within cavities filled with viscous liquids. The dry friction-based gravitational damper proposed in this paper offers several practical advantages. Specifically, it becomes preferable when the damper's rigid body can also serve as a functional component of the satellite, and when hermetic sealing of the spherical capsule is unnecessary. These advantages enable the use of such dry friction dampers in microsatellites and nanosatellites as simple passive actuators for attitude stabilization and control, while simultaneously fulfilling their own function as satellite components. Mechanical and mathematical models are developed, and corresponding simulation results are obtained to demonstrate the dynamics of satellites equipped with dry friction dampers during gravity-gradient stabilization.</p>
