Abstract
Defocussing of the radio frequency beam arises from gravity-induced structural deformations as the antenna rotates about the elevation axis. The new Subreflector Controller generates the axial (z) and lateral (y) offset corrections necessary to move the subreflector, thus minimizing the gain losses due to this defocussing. This article discusses the technique used to determine these offset errors and presents a description of the new Subreflector Controller.
