Headline Details: A 1U CubeSat mission. The main purpose of satellite mission is List and describe 1. A technology demonstration of Electrical Power Supply (hereinafter called "EPS"), On Board Computer (hereinafter called "OBC") , and other bus components. 2. HSU-SAT1 performs three-axis attitude control by combining aerodynamic stabilization and magnetic torquers. 3. The modulated infrared light emitted from our ground station is experimented as command transmission link. The command format conforms to the infrared remote-control system used in electrical appliances. 4. Camera image is downlinked by Slow Scan Television. The camera takes a photograph of the Earth. Image pixel size is 320x240. The photograph taken is converted into analog SSTV signal, transferred to Communication (hereinafter called "COM") , and sent by FM-SSTV downlink. 5. A technology demonstration of gyro sensor and magnetic sensor which has not been confirmed its operation in space. Proposing a UHF downlink using CW, FM SSTV and 9k6 GMSK. Planning an ISS deployment during FY 2020 More info at https://drive.google.com/file/d/1MHkTkzY6-Ef392tC0ZM4WiJg9GIpgpiz/view and https://drive.google.com/file/d/1ic2ldCLomB_0uOGwkq71IasNReXQw7YZ/view ** A downlink on 437.280 MHz has been coordinated**
