The high precision optical beam pointing and tracking technique is one of the most critical technology issues facing the realization of optical intersatellite links. From this viewpoint, we have proposed a new tracking technique using single detector systems. This paper describes design considerations of a pointing and control system for single detector ones with suppressing optical telescope vibrations, which are necessarily caused by the acceleration and de-acceleration of the telescope jimbal mount in tracking the target satellite. This badly influences the control accuracy. The algorithms of the relative angular and angular velocity commands for the telescope to the base body of the satellite, needed for smooth tracking, are derived both in the case of earth observation data and the single detector signals. The formulation of an optimal design method in order to keep both tracking accuracy and vibration suppression of the above are also presented by applying the so called "optimal control theory".
