Problems in designing miniaturized satellite systems consisting of miniaturized constituent elements and missions suitable to miniaturized satellites, and subjects of technical development available for miniaturization are examined and reviewed. Results of reviews on satellite miniaturization of the following subsystems are outlined: (1) communication and data processing subsystem; (2) electric power supply; (3) sensors (optical and inertial sensors, and GPS (Global Positioning System) receivers) and actuators (wheels, RCSs (Reaction Control Subsystem)); and (4) structure and thermal control subsystem. Problems in designing the system are: (1) introduction of commercialized goods technology; (2) anti-space environment measures; (3) user friendly operation system; and (4) disposal of used satellites. Miniaturized satellite utilization missions considered are: (1) technology development mission (scientific and engineering experiments); (2) communication and positioning mission; (3) observation mission; and (4) planet exploration mission.
