| Headline Details: A 6U+ CubeSat. As for many university satellites, the mission objectives of the SONATE-2 satellite can be divided into three different parts: - The operation of an amateur radio payload - The development and operation of the satellite is used for the education of students of our university. In cooperation with the DLR School Lab in Neustrelitz, Germany, it is planned to use the amateur radio payload for the education of high school students. - The operation of a novel payload using artificial intelligence as a technology demonstration in space. The amateur payload of SONATE-2 consists of a VHF transceiver that was already built for the predecessor mission SONATE over the curse of several student theses. For SONATE-2 additional student theses extended the transceiver functionalities. It will provide regular SSTV downlinks with images from the optical sensors included in the AI payload as well as an APRS digipeater and CW beacon. On the education side, the mission will serve as a foundation for different aspects of the university aerospace and computer science engineering program. In the context of practical courses, theses or as student assistants, students can participate in the development of all subsystems of the space and ground segment, including the amateur radio payload and the technology demonstration payload. In the context of mandatory lectures and exercises on space operations every student will also be included in the operations of the satellite. The German Aerospace Center (DLR) offers a School Lab for high school students at the location of our external ground station in Neustrelitz, Germany. Besides experiments on space and satellites, the School Lab includes amateur radio contacts to the ISS under the supervision of licensed local radio amateurs, which they wish to extend to other satellites like in this cooperation with the SONATE-2 mission. The AI payload is a newly designed payload using powerful, but power efficient computing hardware and multiple optical sensors is VIS and IR. It is capable of not only the execution of neural networks but also their training in orbit. Applications include autonomous classification of images on the pixel-level, object detection and anomaly detection. Besides the amateur and educational mission parts, the SONATE-2 mission also has a research objective for the demonstration of novel artificial intelligence technology in the space environments. While the AI payload is mainly operated using a separate up/downlink in the space operation service in S-band, the satellite bus and the amateur payloads are operated in the amateur service. Housekeeping telemetry in the amateur service also contains status information of the non-amateur payload. Proposing CW, SSTV using Martin M1 and APRS downlinks on VHF and a 9k6 G3RUH AX25 telemetry downlink on UHF. Planning a Q1 2024 launch into a 550 km SSO.
