In optical communication links between GEO satellites, all optical beam control functions required for the transceiver may be realized without using external gimbals. Configuration of such a transceiver internal optical system can be designed considering the satellite dynamics in orbit. This paper presents a design of the transceiver internal optical systems, taking into account the accuracy of satellite station-keeping and attitude control as well as an orbital separation. An experimental optics was constructed on the basis of the results for a bidirectional link between satellites separated by about 60 deg in orbit. The attitude control accuracy of + or - 0.1 deg and the satellite station-keeping of + or - 0.1 deg were assumed. It can be utilized to develop a variety of beam-controlling schemes.
