The creation of the nanosatellite standard called Cubesat caused an increase in the number of missions based on small satellites. One of the problems faced during the development of projects with Cubesats is related to the effects caused by the radiation on the electronic components of the satellite. This requires the development of on-board control software to detect and correct errors in orbit so that the mission is not compromised. In this context, this article presents the on-board control system that has been developed for the CONASAT project's Cubesats, a partnership between the Northeast Regional Center (CRN) of the National Institute of Space Research (INPE) and the Federal University of Rio Grande do Norte (UFRN). In addition, some tests and results are also presented, as well as some final considerations.

Um dos problemas enfrentados durante o desenvolvimento de projetos com Cubesats está relacionado com os efeitos causados pela radiação sobre os componentes eletrônicos do satélite. Isso faz com que seja necessário o desenvolvimento de um software de controle de bordo capaz de detectar e corrigir erros eḿ orbita, de modo que não haja um comprometimento da missão. Diante desse contexto, este artigo apresenta o sistema de controle de bordo que tem sido desenvolvido para os Cubesats do projeto CONASAT, uma parceria entre o Centro Regional do Nordeste (CRN) do Instituto Nacional de Pesquisas Espaciais (INPE) e a Universidade Federal do Rio Grande do Norte (UFRN). Além disso, alguns testes e resultados também são apresentados, bem como, algumas considerações finais.

This paper deals with the discussion of the analysis of remote sensing data on onshore oil exploration occurring in the Potiguar Basin, in the state boundaries of Rio Grande do Norte -Brazil, from the perspective of changes in albedo index, surface reflectance and surface temperature associated with to those aspects. The albedo is considered a significant variable in understanding the energy balance that makes up an important element of the analysis of global climate change. Through the use of remote sensing tools and GIS, based on surface reflectivity algorithms and surface temperature from GEObia (GEOgraphic-Object-Based Image Analysis) from the sequence -Pan-sharpened composite, Radiance with atmospheric correction, Reflectance with atmospheric correction, and Surface temperature with emissivity correction, used in scenes produced by OLI sensors (Operational Land Imager) and TIRS (Thermal Infrared Sensor) Landsat-8 satellite, it was possible to determine the variations in surface reflectance and surface temperature, and compare them to index albedo therein the oilfield based on the method 6S + Liang (2000). The research indicates, with the determination of processed values, which areas of oil exploration to the analyzed time, present significant change rates, with a tendency to increase in reflectance and temperature associated with albedo changes, as well as other areas of renewable energy exploration.
