Designs and implementations for CubeSat Colombia 1 satellite power module

Abstract

This article contains the results of the research process, analysis, and EPS (Electrical Power Subsystem) design for the small satellite CubeSat Colombia 1, Project CubeSat UD, Telemedicine and Telemetry, of the Universidad Distrital Francisco José de Caldas. Initially, a theoretical Preliminary Design of the Power Module was established, determining components and topologies of the Module; after the Version 1 of the Critical Design was completed based on the first implementation of the Preliminary Design, the results led to the Final Version of Critical Design. Electrical and physical tests were performed on the Printed Circuit Boards (PCBs), manufactured by specialized companies, with designs of students and teachers in Altium Designer software. For tests, it was necessary to use power supplies, multimeter, oscilloscope, scales, among others. Due to these electrical tests, it can be stated that the Final Version of the Critical Design is reliable; however, it is still important to adequately validate the delivery of the necessary power to the users in orbiting conditions, for future works.
