This paper describes the design and implementation of a multi-mission CubeSat user interface for the SAGE Mission, a student-led CubeSat program. The system includes a web-based interface that provides telemetry visualisation, automated job scheduling, and real-time monitoring. Its architecture is designed to be modular, scalable, and accessible, allowing integration with multiple ground stations and support for various mission configurations. Input from stakeholders played a crucial role in shaping the interface through user evaluations, expert feedback, and digital twin simulations. Our findings highlight the significance of user-centred design in space mission software, particularly in educational and resource-constrained settings. The CubeSat SAGE mission control software enhances the accessibility of multi-mission operations and offers valuable insights into the future of space system interfaces.enconference paper
