Device and method for aligning an optical emitter and receiver beam in satellite connections

摘要

The method involves an extra step involving the combination of a detector error signal with a control parameter, which is performed by an additional summer arrangement whose output parameter acts on a pre-hold unit. The detector error signal can also act via a fine alignment on a second summer arrangement as a fine adjustment angle. The error signal acts as a control parameter for the pre-hold angle and/or the coarse adjustment angle. The fine adjustment angle also acts simultaneously upon the first summer arrangement. The alignment and maintenance of the link are achieved iteratively using the measured parameters.
