Electronic beam squint tracking for land mobile satellite terminals

Preliminary results from an investigation of the applicability of the electronic beam squint (EBS) tracking technique to land mobile satellite terminals. Two systems are described, based on the EBS technique, which use both conventional waveguide and phased-array technology. Results are presented covering the error-detection capabilities of the systems, along with some operational analysis to illustrate the dynamic capabilities of the performance of such schemes. The systems described are intended for use at L-band and Ku -band. Both techniques appear to offer a simple, and hence cost-effective, alternative to the current terminal arrangements
