Computer-aided design, manufacturing and engineering technologies (CAD/CAM/CAE) are
a mainstay in today's industry and therefore they should be an important part in the current …

This paper presents the development of the UPMSat-2 sun sensor, from the design to on-
orbit operation. It also includes the testing of the instrument, one of the most important tasks …

Accurate and simple mathematical models are usually required to assess the performances
of photovoltaic devices. In particular, it is common practice to use explicit models to evaluate …

Solar panels are a key component for most spacecraft as they provide energy to the vehicle.
However, their possible use is not limited only to power generation, as they can also be …

In this paper, the first work carried out at the IDR/UPM Institute within the frame of the
educational innovation project PIRAMIDE is presented. This work is related to photovoltaic …

In this work, a new and low-cost Arduino-Based Data Acquisition System (ABDAS) for use in
an aerodynamics lab is developed. Its design is simple and reliable. The accuracy of the …

In the present work, a new model for Li-ion battery performance is proposed. This model is
based on the energy discharge level (in relation to full capacity), and was developed after …

The thermal modeling of small satellites (up to 100 kg) is crucial for predicting and managing
their operation, and may present significant differences when compared to the thermal …

Abstract Space systems require technologies intended for power generation and
management most of the time. Within the Electric Power Subsystem, one or a group of …

This paper describes an accurate model of the Electrical Power Subsystem (EPS) of the
Thermal Analysis Support and Environment Characterization Laboratory (TASEC-Lab), a …
