Latest Patents
One of Hirshfield's latest patents is titled "Satellite communication service with non-congruent sub-beam coverage." This invention describes a method for use in a satellite communications system that includes at least one satellite with forward and reverse beams. Each beam is comprised of sub-beams that relay user communications between a ground station and user terminals. The first embodiment of this invention allows for the optimization of forward and reverse antenna systems without the need for congruence between the sub-beams at the Earth's surface. The second embodiment optimizes signal flow by determining user terminal RF signal conditions and reallocating sub-beams accordingly. This ensures that the totality of the sub-beams of the forward beam is non-congruent with those of the reverse beam while maintaining overall congruence at the surface.
