Abstract
A space diversity communications system usable with a multi-direction time division multiplex communications network which consists of a plurality of scattered satellite stations and one central station. While the central station is provided with a single antenna, each satellite station is provided with two antennas, main and supplementary. The central station, responsive to received signal, produces a control signal for each satellite station and sends it the satellite station. The satellite station selects either of two antennas in response to the control signal, thereby increasing radio transmission quality on a satellite-by-satellite basis.
