The development of bus-structure for the further GEO satellite is described. The target of the further GEO satellite is to be the satellite with 8 kW solar generation, 3650 kg launch weight, and sufficiently global competitiveness on the next decade. The target weight of the bus-structure is lower than 215 kg (lower than 5.9 % of launch weight). The design and mechanical tests of the bus structure have been successfully completed.
