Artificial satellites as a research area encompasses the scientific and engineering study of human-made objects intentionally placed into Earth or other celestial orbits for observation, communication, navigation, and experimentation. Research focuses on orbital dynamics and mission design, attitude determination and control, space environment interactions (radiation, plasma, micrometeoroids), and advanced materials and power systems for long-duration operation. It also includes development of miniaturized platforms (e.g., CubeSats), payload instrumentation for remote sensing and scientific measurements, formation flying and constellations, on-orbit servicing, autonomy and fault management, and the impacts of satellite proliferation on space traffic management and orbital debris mitigation.
Despite the complexity of the operation, ERMIS-3, an 8U CubeSat developed by the National and Kapodistrian University of Athens, has established a link with an optical ground station, marking an important step in validating ...
