Headline Details: A 1U CubeSat mission. The Pleiades-Cerberus Orbiting Laboratory aims to fulfill two significant objectives in the realm of space exploration and education. The primary mission is to establish a unique, space-based laboratory platform. This initiative allows students and radio amateurs across the globe to actively engage with and gain practical insights into the space environment. By doing so, the project not only enhances educational opportunities but also provides invaluable hands-on experience in a space science mission. The Pleiades-Cerberus Orbiting Laboratory second goal is to offer flight heritage for a variety of affordable, open-source hardware components. This is a critical step towards the advancement of future educational and amateur satellites. These goals not only promote practical learning and innovation in satellite technology but also inspire students and enthusiasts worldwide to explore the potentials of radio communications and satellite development. In essence, the mission serves as a beacon, inviting participation and sparking new ideas in the field of amateur space exploration. The Pleiades-Cerberus mission represents a significant advancement for the global amateur satellite community, offering open access to a satellite in Low Earth Orbit. This satellite, equipped with various sensors and scientific instruments, is accessible to students and radio amateurs through up-and-down links in the amateur bands. Users can uplink commands, enabling functions such as instant sensor data readouts and an "echo" feature that rebroadcasts the uplinked packet as a downlink packet. The mission enhances user interaction by alternating between Long Range (LoRa) and Frequency-Shift Keying (FSK) communication modes. This approach caters to a wider range of users with different technical capabilities. Additionally, the mission repeater mode will enable monthly competitions for the amateur radio community where those who have the top three strongest signals received will be rewarded with a commemorative sticker, fostering a sense of community and achievement. Proposing a UHF downlink using LoRa and FSK. Telemetry is formatted according to TinyGS requirements. https://github.com/G4lile0/tinyGS/wiki. Planning a Exolaunch from Vandenberg NET June 1st 2024 into a 525 km sun synchronous SSO. More info at https://www.broncospace.com/ **A downlink on 437.400 MHz has been coordinated**
