Abstract

This paper presents the design and implementation at the hardware level of the OBC-OBDH subsystem (On-Board-Computer On-Board Data Handler) to meet the requirements of the CubeSat QB50 project, in addition, different tasks are performed at the software level to simplify the subsequent development (the implementation of the FreeRTOS real-time operating system has been carried out, and a simple example has been prepared that involves the use of all the necessary modules). The development of this module is justifiable at an academic level, since the QB50 project impacts on different aspects the academy (development of satellite systems), it must be taken into account that the QB50 challenge is presented to all the universities of the world and has a great impact on third world countries, providing the possibility of massive development and low launch costs.
