High-Precision Geocasting for Leo Satellites Using Combined Spatial Data Focusing and Beamforming
An application of spatial data focusing (SDF) for geocasting through low Earth orbit satellite communications is proposed. SDF is a high-precision solution to restrict data to a given zone, but lacks of power gain. In order to compensate for the huge path loss experienced during transmission, additional antennas are included to replicate the signal of the antennas implementing SDF. By doing so, the geocasting benefits from the high resolution of SDF and gain from beamforming. Simulations show the applicability of SDF to current system technologies, and open new perspectives in wireless geocasting.
