“…The basic parameters usually considered to develop a simulation model of a battery are the capacity , voltage , current , temperature , state of charge , load and internal resistance , to mention a few (Acharya et al, 2019). Notice that, among the various configurable parameters of the above mathematical models, the capacity, , is usually considered of particular interest for its ability to drive the battery behaviour and being associated to its degradation (Dominguez-Jimenez et al, 2020).…”

At the European Space Agency (ESA), Modeling and Simulation (M&S) plays a fundamental role during the lifetime of a spacecraft, being used from the design phase to the testing and during operations in space. In particular, the European Space Operation Center (ESOC) makes use of M&S tools for various tasks such as monitoring and control, procedure validations, training, maintenance, planning and scenarios investigation, to mention a few. Moreover, moving towards the digital twin paradigm, simulation models are gaining growing attention with the expectation to provide ultra-fidelity capabilities to represent the live status and dynamics of flying spacecraft. In this respect, M&S tools embed general physics-based models and disciplines characterized by configurable parameters which have to be calibrated in order to mimic the behavior of the actual flying spacecraft. However, their calibration requires a large number of simulations which are unfeasible to be obtained through computationally expensive highfidelity simulation models. In this light, the present work proposes the use of a surrogate model-based approach for the calibration of simulation models of spacecraft. The approach integrates a computationally inexpensive deeplearning-based surrogate model. The approach's effectiveness is shown by its application to real flying Earth observation satellite data and simulation models.

“…Calculation of β is given in (1) and the parameters are defined in the nomenclature [24]. The rate of change of Γ with time can be calculated using the approximation of earth's circular orbit around sun, which is 2π/365.25 rad/day, while the time rate of change of Ω is calculated in (2). The eclipse time in LEO is calculated in (3) where the orbital period of the satellite orbiting the earth with radius R o is also provided.…”

“…Satellite missions have increased in recent years thanks to CubeSats, which made possible a variety of exploratory and scientific space applications [1][2][3][4][5][6]. For example, satellites have improved solar power predictions and aid in planning of PV plants for economic viability by providing irradiation data [7,8].…”

“…El sistema de energía eléctrica (EPS, por sus siglas en inglés) es el responsable de gestionar la generación, almacenamiento, regulación y distribución de la energía eléctrica en el satélite (Gonzalez-Llorente, 2016). Por esta razón se hace esencial el uso de baterías para el almacenamiento de energía eléctrica y de esta forma poder complementar el abastecimiento de energía eléctrica del mismo (Acharya et al, 2019). Además, el EPS se encarga de la regulación de energía eléctrica para mantener la tensión y corriente eléctrica a niveles adecuados para que los dispositivos electrónicos del CubeSat, y también distribuye la alimentación de energía eléctrica a los demás subsistemas (Aung et al, 2020).…”

Un satélite es un dispositivo que se sitúa en órbita alrededor de la Tierra con fines científicos, militares, educacionales o de comunicaciones. Se pueden clasificar según su peso como: satélites grandes, que pesan más de 1,000 kilogramos (kg), satélites medianos, que pesan entre 500-1,000 kg, y satélites pequeños, que pesan menos de 500 kg. Dentro de los satélites pequeños se encuentran los nanosatélites, los cuales pesan entre 1-10 kg. La principal ventaja que poseen los nanosatélites es que son capaces de realizar misiones complejas a un menor costo. Dentro de las limitaciones que estos presentan es que tienen poca capacidad para captar y almacenar energía debido a su tamaño. Considerando la importancia del sistema de energía durante el funcionamiento de los satélites, este artículo analiza los modos de fallos que se presentan en el sistema y cómo estos afectan a los sistemas de generación y almacenamiento de energía. Para la simulación de estos sistemas se determinaron la cantidad mínima de paneles solares y baterías necesarios para su correcto funcionamiento. Los resultados obtenidos muestran que con este análisis se logra dimensionar correctamente el sistema de gestión de energía, reduciendo el tamaño de estos y a su vez el peso dentro del satélite.
