Abstract

Academic CubeSat missions face significant challenges in developing robust flight software with limited resources. This paper addresses this issue by presenting a case study on the development and validation of the software for the On-Board Data Handling (OBDH) system of Aldebaran 1, a 1U CubeSat. The software architecture, adapted from the open-source FloripaSat-2 platform with FreeRTOS, is designed to manage antenna deployment, process telecommands, and persistently store mission data. System validation was performed through end-to-end system tests, utilizing ground stations to simulate a complete operational cycle. The tests confirmed the correct implementation of the architecture, including the deployment timeline, command processing, and data persistence across reboots. Notably, the power management strategy was simplified to remote radio control due to hardware limitations. This work presents a pragmatic and successful development cycle, serving as a technical reference and a set of lessons learned that provide valuable contributions to other university-led CubeSat projects.
