Analysis is given for the dynamics of a spinning satellite with four radial wire antennas. In this analysis, generalized model is used, in which, mass properties of wire antennas are not equal and antennas' attachment points on the satellite have some amounts of offsets from the satellite CG (center of gravity) plane. Each antenna is modeled as a physical pendulum. They have two degrees of freedom : in-spin plane and out-of-plane motion. Lagrangian with 14 degrees of freedom is obtained, and then equations of motion are derived. A set of equations can be divided into three groups. From a modal analysis for each group, the effects of wire antennas asymmetry and their offsets on the satellite attitude motion is revealed. Numerical simulation results of GEOTALL satellite are also given.
