SONATE-2 is a 6U+ CubeSat for technology demonstration developed at the University of Würzburg. It was launched on SpaceX’ Transporter-10 mission into a 527x505 km Sun synchronous orbit on March 4, 2024. Recent missions have used AI for on-board image analysis only with models trained on ground. The SONATE-2 mission introduces on-board training of the AI models, allowing new applications like anomaly detection, which are only possible by training in space using images captured on-board. This is an important feature for future interplanetary missions, where no sufficient image data is available for pre-training AI models on the ground and supervised training is difficult due to a limited communication link. The primary goal of the SONATE-2 mission is the in-orbit demonstration of a new AI processing platform, which was developed based on COTS hardware. Secondary objectives include several ADCS experiments, tests of a pulsed plasma thruster for attitude control, and the operation of an amateur radio payload. During the first weeks of its operation in orbit during LEOP and commissioning the SONATE-2 performs as expected. All systems have been checked out and the post-launch calibration of the AI payload and satellite bus has started. The amateur radio payload was activated on several days and was successfully received by radio amateurs worldwide.
