When satellite broadcasting programs are received on mobile in built-up urban areas, visibility of the broadcasting satellite is only about 65%. In order to obtain a high receiving rate in this situation, three diversity methods are available : space diversity of the receiving side, time diversity, and space diversity of the sending side (orbital diversity). This paper compares the ability of these methods to improve receiving rate. Time diversity and orbital diversity are superior methods; either can improve reception rate to over 90% in urban areas. It is consequently possible to provide satellite programs to people on mobile in urban areas.
