The Quality of Service (QoS) and spectral efficiency in Land Mobile Satellite (LMS) communications drops drastically in the presence of shadowing and multipath fading. The method for increasing QoS and spectral efficiency, is done by without any increasing in total transmit power, antenna gain or bandwidth by using Multiple-Input Multiple-Output (MIMO) techniques. In order to carry out the performance assessment this paper addresses related MIMO satellite propagation channel modelling issues which lead to a new mathematical model to accommodate the multi-satellite transmission. The omni directional antenna's two RHCP and two LHCP used for complete analysis.
