The 2005SAT is designed to fit within the standard fairings for all compatible launch vehicles including Ariane IV, V and Atlas II/III. The 2005SAT configuration is compatible with single launch, upper or lower position of dual launch. Two offset-fed Gregorian antennae are located on the earth panel of the 2005SAT for Ku-band and Ka-band communication services. The 2005SAT bus is 3-axis stabilized platform both for transfer orbit and on-orbit operations. The attitude control logic is used quaternion using gyro data and have the compensation logic for gyro bias update by the ESA and the SSA data. The 200SSAT Electrical Power Subsystem (EPS) is designed a regulated directed-energy transfer configuration that minimize the losses between the solar array and loads while minimizing the complexity and mass of load power converters. The duel-mode propulsion scheme is selected for 2005SAT. TC&R subsystem is conceptually designed to determine specifications of processor speed, RAM and ROM size, command-telemetry format and data bus type
