Abstract	The next generation of mobile satellite systems (MSS) will use the constellation of satellites in non-geostationary orbits for global communication, The proposed S-PCNs are Iridium, ICO, Globalstar, Odyssey and Ellipso. The first two systems propose to use a time division multiple access (TDMA) scheme and the others a code division multiple access (CDMA) scheme. It is claimed that CDMA based S-PCNs can share the allocated frequency bands due to the interference resistant property of CDMA. In this paper, we present the results of the investigation on the total system capacity achievable by totally overlapped band sharing between the two systems such as Globalstar and Odyssey under perfect and imperfect power control conditions. Results for a single satellite system operating in a band segmentation approach are also presented for comparison, again under perfect and imperfect power control.
