Compatibility of Integrated Satellite Systems with Another Satellite System Operating in Adjacent Beam

Authors: Hyemi Gam, Dae-Sub Oh, Bon-Jun Ku


This paper addresses the analysis of the interference between complementary ground component (CGC) base station and mobile earth station (MES). In the frequency sharing scenario between CGC base station and MES, the interference from the adjacent beams must be considered. In this paper, we estimated the interference to MES of an integrated satellite system and the result is presented as the carrier to interference ratio(C/I) with respect to the number of CGC base station in the adjacent beam and the ratio of satellite beam center radius to the total beam radius (R1/R). By using these results, we can determine the minimum separation distance between the CGC base stations of adjacent beam and MES for compatibility. This result can be applied to the CGC base station of an integrated satellite system for the effective frequency sharing.

Keywords: Interference, MES, Integrated satellite system, frequency reuse pattern, CGC base station, frequency sharing
