| Headline Details: This is a 1U CubeSat mission to demonstrate CubeSat capabilities that can observe solar radiation and transmit along with beacon signal. It is purely for non-commercial purposes as a technology demonstration mission. 1. Mission Compliance: The CubeSat mission complies with IARU provisions 1.56, 1.57, and 25 by using amateur frequencies for non-commercial purposes, keeping amateur and other mission subsystems separate, and ensuring no interference with other services. 2. Advancement of Amateur Satellite Service: The mission demonstrates small satellite technology for solar radiation observation, promoting amateur satellite use for scientific research, and fostering global participation through open data sharing. This mission will have an amateur FM transponder for amateur radio operators. 3. Educational Impact: The satellite will serve as an educational tool, offering opportunities for amateur operators to engage with space technology and contribute to real-time mission monitoring and data analysis. 4. Global Amateur Participation: Amateur radio operators worldwide can track the satellite, decode its telemetry, and assist with mission success by providing feedback, contributing to satellite health monitoring, and participating in propagation studies. The FM Repeater can be used by amateur radio operators globally to establish two-way contacts. 5. Data Accessibility: The CubeSat will broadcast a beacon signal and telemetry data that amateur operators can receive, decode, and analyze, actively engaging them in the mission beyond just receiving information. Proposing a UHF downlink for telemetry using 9k6 FSK and a U/V FM transponder. Planning an ISRO launch from Sriharikota in Feb/March 2026 into a nominal 500km circular orbit. | ||||
