Design and Implementation of an Educational CubeSat Constellation

The development of satellite constellations has advanced global communication, Earth observation, and research. CubeSats have emerged as a cost-effective, scalable solution, particularly for educational applications. This Paper explores the design and implementation of an educational satellite constellation consisting of three 1U CubeSats. The constellation operates in the UHF band using the AX.25 protocol for real-time communication and telemetry transmission. The design process for the satellite subsystem s includes commercial off-the-shelf (COTS) components explicitly selected to meet design requirements . The Paper also examines inter-satellite communication, mission design, and system performance , adding to the growing field of low-cost satellite deployments emphasizing their educational potential.
