Energy Harvesting System for aerospace application

[ANGLÈS] The Energy Harvesting is really interesting concept nowadays because it consists in get energy from the environment that is already there. Nowadays application and commons such as nodes of a wireless network self-powered, the flexibility to locate them give an interesting advantages to allocate the network in strategic points or even to difficult places. Alternatively, it can be set out from this energy source a sub-system inside the other sub-system more big, that can be self-powered, like it could be an RF beacon for aerospace mission. For this reason the aim of this project is to study, design and implement a Harvesting system, with a thermo-electric principle that will be allocated behind the solar panels of a satellite designed by the UPC, the CubeCat1. The system consist in a thermo-electric generator block, a Power Management stage, and a sensors / process stage of information and at last a communication stage. Once the system is described, the results under nearly space environment are showed, as well the downlink test with the Ground Station are shown. The last part also includes a treatment of the signal capable to detect and identify the word sent under a noisy environment of the open band transmission. In this sub-system, built in the CubeCat-1, can works independently from the rest of the satellite how it integrates all the electronics systems to monitories, self-power it and transmit the signal. In this way is really interesting in the capability to miniaturize the experiments and the low power system that it could be implemented. [CASTELLÀ] El concepto Energy Harvesting es muy interesante ya que consiste en la obtención de energía a partir del ambiente que ya está presente. Algunas aplicaciones actuales y comunes son por ejemplo los nodos de una red Wireless autoalimentados, su facilidad de colocación la hacen interesantes para completar una red capaz de llegar a puntos estratégicos. Alternativamente, se puede plantear que a partir de esta fuente de energía, subsistema dentro de otros sistemas más grandes, se puedan auto alimentar, como podría ser una baliza RF en una misión aeroespacial. Por este motivo se ha realizado el estudio, diseño y implementación de un sistema Harvesting, con un principio termoeléctrico que se situará detrás de las placas solares de un satélite diseñado por la UPC, el CubeCat-1. Este sistema consiste en una etapa de termogeneración, una etapa de Power Management, una etapa de sensado y procesado de la infor
