| Abstract(in English) | In recent years, several global network systems using non stationary satellites have been proposed. Some of them are announced to start services within years. Those global network systems should handle a lot of earth stations in the world. Above reason, most of the systems equip multiple beam antennas. Multiple beam is one of useful technique to improve system capacity for communication systems. However, LEO satellites move through the users so that on-going calls should be handed over from satellite to satellite and/or from beam to beam. In this paper, a method for reducing the number of beam-to-beam handover by changing the shape of beams is proposed. We propose beams shaped silt and directed parallel to the compound vector of velocity of the user relatively to the satellite and velocity of the earth rotation. |
