Abstract
The method and the device of the present invention are used for aligning a transmitted and a received beam in satellite connections for the purpose of establishing and maintaining a connection between satellites by optical communications means. The device includes a control unit (3), to which a coarse adjustment unit (7), a fine adjustment unit (6), and a lead correction unit (8) are parallel connected. The parameters of the received beam (4) and also the angular values of the transmitted beam (15, 16) can be corrected by means of various summing members (5, 12, 14) in such a way that precise tracking of the received beam is achieved.
