Phased array beam forming antennas are widely used in LEO satellite systems as well as in ground terminals. Those electrically steerable antennas (ESA) operate in discrete steering angles, which leads to an antenna gain fading, when the Tx and Rx pointing directions are not aligned precisely. As the pointing alignment precision varies continuously during a satellite flyover, the antenna gain will vary accordingly. In this paper we will show, how the impact on the spectral efficiency of such a system design can be mitigated by using more than one satellite. We will investigate the opportunities of multi satellites scenarios in fixed, determined distances as well as in randomly different distances and randomly different flyover paths.
