| Headline Details: The 12U satellite is fully designed by amateur radio operators from University of Science and Technology of China, with missions of investigating advanced millimeter-wave satellite communication and UHD video transmission technologies, and provide hands-on access for amateur radio enthusiasts and students to interact with next-generation communication/remote sensing payloads Subsystem Missions UHF/VHF Transceiver Low-IF software-defined transceiver; Uplink: 146 MHz amateur radio band; Downlink: 436 MHz amateur radio band; Telemetry downlink, telecommand uplink and FM repeater; 47 GHz Transceiver SDR transceiver with ~100 MHz bandwidth; DVB-S2(X)-compliant downlink for UHD video/data transmission; DVB-S2(X)-based TDD-FDMA regenerative transponder for video call/data packets. Video Camera 8K 60 fps UHD CMOS sensor with wide-angle lens assembly and switchable bandpass filters; Observation of upper atmospheric luminous phenomena, with emphasis on Transient Luminous Events (TLEs) such as sprite lightning. Light Beacon LED-based system with >2,000 lm brightness (peak apparent magnitude +7); Low-speed Morse-coded blinking mode (naked-eye visible) and ~100 kSps modulation capability; For optical communication technology verification and high-precision orbit determination via optical beacon tracking. Payload for Children Designed, implemented, and built by affiliated secondary school students; Focuses on simplified programs with 6-month prototyping cycles. 5.5 Explain in plain text how your mission(s) complies with provisions no. 1.56, 1.57 and 25 (see Annex 1); how will your mission contribute to the advancement of the amateur satellite service; and how will amateur operators around the globe be able to participate in your mission, besides just receiving the satellite telemetry? With its 47 GHz transceiver, our mission is expected to be the world’s first mmWave amateur radio satellite, and significantly expand the range of frequencies and bandwidths practically available for amateur and amateur-satellite operations. Photos and videos captured by UHD camera will be downlinked by the 47 GHz transceiver, and attract more people to explore amateur radio satellite. Our UHF/VHF transceiver will provide FM voice transpond, for amateur radio to communicate with others. And our light beacon will provide chance of verifying optical communication technology. The payload for children will give children and youth more opportunity to explore space and satellite, and encourage more youth join in the amateur satellite activity. Global operators could participate in with controlling UHD camera via VHF uplink commands; receiving 47 GHz-downlinked UHD videos/photos; conducting video calls/data exchanges via regenerative transponder. They can use UHF/VHF transceiver to transpond FM voice,or control light beacon by VHF uplink to explore the visible light communication technology. Proposing downlinks that will use : 435-438 MHz: 25K0F3EJN 300HF1DAN 1K20F1DAN 9K60F1DAN 47-47.2 GHz: 84M4D1DDN 13M5D1DDN 2M70D1DDN 5M40D1DEN 270KD1DEN 5M40D1DAN Planning a Q3 2027 launch into a 600 km polar orbit.
