Abstract

A subreflector tracking method, apparatus and system incorporating sensor feedback of the precise subreflector angular position of a nutating subreflector. The subreflector nutation generated by coupling the subreflector, off center, to a rotating support. Monitoring of the received signal strength peak during a rotation of the subreflector generatma an error vector designating a direction in which to move the subreflector to track the signal.
