Status on laser communication activities at Tesat-Spacecom

This paper details the progress in laser communication activities of Tesat-Spacecom. Besides the EDRS program (European Data Relay System) update of in-orbit Laser Communication Terminal (LCT) performance, with more than 88.730 data relay links executed (status Aug 2024), we report on the successful inter-satellite operation of the SDA compatible SCOT80 LCTs on Kepler S/Cs and share recent results. In addition, we present the status on our access terminal SCOT30, targeting the small LEO user segment. Our intradyne development activities have been continued and the algorithms have been further optimized for the atmospheric turbulent channel. We will share the latest results and findings.
