| Headline Details: This satellite is a 2U size CubeSat equipped with a camera for photographing the earth, a sensor for checking the state of the satellite, and an attitude control device with the following two missions. 1 camera mission In response to commands from the ground station, the satellite-mounted camera photographs the earth from space and transmits the image data to the ground. Also, in order for amateur radio users around the world to voluntarily acquire image data taken by this satellite by radio, the date and time of image transmission will be published on the website and SNS. Encouraging amateur radio operators to receive radio signals contributes to the improvement of radio technology of amateur radio users. 2 Digitalker mission Audio data is transmitted from the ground station and stored in the satellite. The voice data is transmitted from the satellite as an analog FM voice signal, and a message is broadcast from space. The date and time the message will be sent will be published on the website and SNS so that general amateur stations around the world can receive the audio signal with relatively simple equipment. Promote the use of satellite radio waves in each country and increase interest in amateur radio by providing technical cooperation for using satellite radio waves with sister schools of universities and high schools such as Lithuania, Australia, Kenya, South Korea, and Taiwan. Contribute to improvement and advancement of wireless technology. The communication and technical research that we are trying to do is mainly to conduct a demonstration experiment of transmitting image data taken by this satellite wirelessly to an amateur radio station on the ground side, encouraging amateur radio operators to receive it, Contribute to the improvement of radio technology for amateur radio users. Regarding the satellite orbit necessary for amateur satellite design, high school students around the world can receive this satellite at the same time and share the position information, so that the orbit calculation can be verified. We will work with high school students around the world to learn the technology of receiving satellite radio waves with simple amateur radio equipment and build a network to get them interested in amateur radio technology. Proposing a UHF downlink with 20 wpm CW, 1k2 AFSK, 9k6 GMSK and digitalker voice. Planning a deployment from the ISS in June 2024. More info will be available at https://gifuhs2022.wordpress.com/ **A downlink on 437.090 MHz has been coordinated** | ||||
