Abstract :
There are many Ku band linearly polarized (LP) space assets covering different service areas for fixed satellite services (FSS). On the other hand, circularly polarized (CP) terminals are more economical in manufacturing and installations as comparing to compatible LP terminals. The presented techniques will enable satellite operators to cost-effectively service Ku band VSAT users, either fixed or mobile, via LP space assets in Ku band. A method for grouping multiple LP satellite transponders through Wave-Front (WF) Multiplexing (muxing) techniques is presented. Grouped LP transponders become accessible efficiently by CP ground terminals and vice versa. This method consists of a polarization converting processor in a ground hub with our modifications of ground user equipment and satellite assets. In addition, applications of WF muxing techniques to satellite communications offer many advantages, including improved flexibility and utility efficiency of existing space assets. Proposed methods enable service providers to service CP VSAT terminals equally well either through LP or via CP space assets, and teleport operators with greater flexibility in how they manage their assets.
