Ground Station Tracking of Dual Linearly Polarized Satellites

Abstract

A new generation of communication satellites carry traffic in both planes of linear polarization within the common carrier band. The tracking of these satellites puts a minor additional burden on the tracking system of the attending ground station inasmuch as communication signals at the beacon frequency, but in the orthogonal plane of polarization, form an additional noise source for the tracking ing system. This paper analyzes a dual channel monopulse tracking system using a simplified monopulse feed intended for tracking of dual polarized domestic satellites. In addition, trade-offs for the selection of system parameters are presented.
