OptiSat is a Greek technology demonstration satellite designed to test laser-based communication technologies and automatic on-orbit data processing.[1][2][3][4] The 6U CubeSat-type small satellite was developed by the Greek company Planetek Hellas[5] and includes a SCOT20 laser terminal built by the German company TESAT.[6][7] The satellite is also testing machine learning-based image processing technology intended for aiding the optical communication link by automatically selecting cloud-free ground stations.[8] The development of the satellite was supported by the EU's and ESA's Greek CubeSat In-Orbit Validation programme. It was launched on the Transporter-16 flight of the Falcon 9 rocket on 30 March 2026.[1][9][10][11][12]
