The device for the control of the beam alignment in satellite laser communications systems has a digital signal processor (24), which has been inserted between an input interface (21) and an output interface (23), and to which a program memory (25) and a data memory (26) are separately connected, in which parameters are also stored, and which comprises sensors (171, 172, 173) and actuators (174, 175, 176) for aligning the laser beam with the counter station. The signal processor (24) contains an intermediate memory (240) for floating point and fixed point operations and further calculating units (241, 242, 243), as well as two access generators (244, 245). Highly flexible and very efficient control systems can be implemented by the employment of such a digital signal processor. By means of an adaptive control it is still possible to operate beam alignment systems at full performance levels, even after components have been degraded. The adjustment outlay for the optical components is drastically reduced because of auto- calibration.
