Systems Engineering of a Brazilian Amazon Imaging CubeSat Constellation: FritzSAT Mission

Abstract

The FritzSAT mission aims to develop a constellation of nanosatellites dedicated to imaging the Brazilian Amazon, addressing the strategic importance of the region and the growing demand for precise environmental data. Despite the presence of existing monitoring systems, significant gaps persist in coverage, revisit frequency, and, notably, the autonomy of private companies in acquiring environmental data. This lack of autonomy hampers these companies' ability to effectively meet their operational and strategic needs, resulting in a dependency on external data sources and limiting innovation in the sector. This study details the initial phase of systems engineering for the FritzSAT mission, and was structured into four key stages: analyzing the environmental monitoring scenario in the Amazon, identifying and analyzing stakeholders, defining mission goals and objectives, and estimating potential system configurations. The scenario analysis involved a comprehensive evaluation of the primary entities responsible for monitoring the Amazon, their data requirements, and relevant data suppliers. A subsequent feasibility analysis of the proposed configurations led to the identification of a constellation of nanosatellites with segmented missions and the definition of operational concepts and system interfaces. This structured framework serves as a guide for the ongoing development of the project, providing a solid foundation for the subsequent phases of the FritzSAT mission, which aims to enhance the autonomy and effectiveness of environmental monitoring efforts in the Brazilian Amazon.
