CubeSat achieves challenging laser link to ground
Despite it being a complex 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 optical communications on small satellites. The demonstration, supported by the European Space Agency (ESA) and achieved using optical terminals developed by Lithuanian company Astrolight, happened only weeks after the satellite’s commissioning.
