Hysteresis dampers are commonly used in Passive magnetic Attitude Control System (PACS). In PACS these
rods produce a damping torque and reduce the satellite angular momentum and angular velocity. In this paper, a spin
satellite was investigated which utilizes a passive magnetic damper consisting of magnetic hysteresis rods aligned with
principal axis or spin axis of satellite and de-tumbling of the satellite, and the pure spin was achieved.
An analytical model was presented to analyze hysteresis damper and a numerical simulation was performed to obtain
dynamic properties of the spin attitude. In addition, assuming a dynamic imbalance, attitude behavior and damper effect
on the spin rate of satellite were analyzed. The behavior of this passive magnetic stabilized satellite was simulated from
the initial post separation phase.
