| Headline Details: Pleiades - Squared has two primary missions. The first is to fly a 1U CubeSat built entirely by students at Cal Poly Pomona. The 1U CubeSat shall be based on the PROVES (Pleaides Rapid Orbital Verification Experimental System) open-source CubeSat architecture being developed for educational use. Pleiades - Squared will also contain additional scientific experiments built by students in laboratories at Cal Poly Pomona. Particularly, this satellite shall carry a low-cost gamma ray detector as part of a particle physics citizen science project known as the Cosmic Watch. Students participating in the Pleiades - Squared mission shall gain valuable experience with the integration, launch, and operation of a spacecraft as a part of their academic experiences. Students, citizen scientists, and radio amateurs who interact with the satellite will also be able to receive and analyze in-space radiation data from the Cosmic Watch experiment. The second is an expansion of the Pleiades CubeSat Cluster Initiative, which exists to develop and demonstrate distributed spacecraft technology. Pleiades - Squared intends join the existing Pleiades Yearling and Sapling Sempervirens CubeSats (previously coordinated with emission designator 125KX1DCN) in demonstrating satellite-to-satellite and satellite-to-satellite-to-ground relays. Depending on final orbital parameters, the ultimate goal will be to conduct store and forward data relay between radio amateurs across the United States. Proposing a UHF downlink using LoRa. Transmission format is LoRa with BW = 125 kHz, Spreading Factor = 12, Coding Rate = 8, Preamble Length = 8. In the event of a change of LoRa parameters, details will be published on the SSI github here: https://github.com/stanford-ssi/sapling. Telemetry is formatted according to TinyGS requirements. https://github.com/G4lile0/tinyGS/wiki Planning a Exolaunch/SpaceX launch from Cape Canaveral in April 2023 into a 525 km SSO. **A downlink on 437.400 MHz has been coordinated** | ||||
