Abstract : The article deals with a spin stabilized platform. In order to isolate the system from external moments it is suspended through its center of mass by means of a cardan. Deviation from ideal suspension, such as friction effects in the bearings and in the surrounding environment together with external disturbances, generate vibrations in the natural frequencies of the system. These vibrations should be suppressed by means of damping effects. The damping should not impair the isolation of the platform from its environment (as in the case of damping in the cardan bearings). The simplest model of a cardan suspended gyro involves only one natural frequency, termed the nutation.
