General view of the satellite in stowed configuration in the Z-direction
efficient volume usage. So they are fixed jointly on the basis block case and the
lower frame. Hence, the fourth wall of the basis block case is employed.
One of the main objectives in the configuration process is to make the design
and mass distribution as symmetrical as possible, so the arrangement of the
remaining equipment should follow this concept. Three faces of the lower frame
have already been used as mounting surfaces, while the fourth one in negative X-
axis is partially occupied by the power subsystem electronic modules, PCU and
CLU. The first face located at the positive Y-axis carries the X-band electronic
module, while the second face located at the positive X-axis carries the ODCC,
which consists of three identical modules. Two S-band electronic modules and
