 \chapter{Introduction} \label{ch:introduction}
 
-The FloripaSat-2 is a satellite project of a 2U CubeSat (10$\times$10$\times$22,70 cm). This nanosatellite is the sequence project of the FloripaSat-1 CubeSat \cite{floripasat}, both developed by SpaceLab \cite{spacelab}. This second project is being developed in partneship with INPE\nomenclature{\textbf{INPE}}{\textit{Instituto Nacional de Pesquisas Espaciais.}} (\textit{Instituto Nacional de Pesquisas Espaciais}), who is supplying the main payload of the mission: The EDC board (\textit{Environmental Data Collection}) \cite{edc}. This project is part of the ``GOLDS\nomenclature{\textbf{GOLDS}}{\textit{Global Open Collecting Data System}}'' constellation (``Global Open Collecting Data System''), a collaborative CubeSat constellation for environmental data collection planned as part of the Brazilian space program \cite{golds}.

 This project started just after the launch of FloripaSat-I (first half of 2020) and is planned to be launched in 2022. Most of the embedded electronics is partially or totally based on the FloripaSat-I satellite, with the same and/or improved versions of the modules. In other words, this project has at some level a flight heritage.

 \subsection{Working Breakdown Structure}
 
+The Working Breaking Structure (WBS\nomenclature{\textbf{WBS}}{\textit{Working Breakdown Structure.}}) is presented as a diagram in \autoref{fig:wbs}. The WBS is divided in work-packages (WP\nomenclature{\textbf{WP}}{\textit{WP.}}) as can be seen in the diagram. The description of each WP is detailed below.
