Two tracking sensor breadbroads have been developed for the European SILEX program. Critical requirements to be met by these sensors include the determination of the 1-sigma position of the focused laser spot on the detector surface to accuracies of

Optical communication between satellites in orbit requires highly accurate tracking of an incoming laser beam, to allow the generation of necessary control signals for the pointing mechanisms. For the SILEX system planned by ESA the tracking sensor i
