Overview (resum en anglès):
This thesis presents the integration of the existing 3Cat-8 software logic with a new On-Board Computer (OBC) developed by EnduroSat. The work focuses on implementing robust task management to support the satellite's operational modes, along with establishing a reliable communication interface between the OBC and the Command & Control Segment on Earth. To enhance mission performance, the software was expanded beyond its baseline functionality, incorporating real-time task scheduling, memory management, and hardware-level communication. The development relied on low-level programming and embedded system principles, with significant effort dedicated to understanding and adapting to EnduroSat's proprietary SDK and protocol stack.

The result is a modular and reusable Command & Control API designed to streamline satellite operations and simplify future mission integrations. In parallel, a full implementation of the OBC's Concept of Operations (ConOps) was developed, aligned with EnduroSat's updated SDK structure. This includes autonomous mode handling, fault detection integration, and the operational logic necessary for real-time satellite state transitions. Together, these components form a comprehensive, scalable control framework that enhances both ground and onboard software coordination for the 3Cat-8 mission.
