             abstract = "Extreme weather events are one of the major character in climate 
                         change. Predicting these complex meteorological phenomena requires 
                         high-resolution numerical weather prediction (NWP) models and the 
                         maximum amount of observational data available. Nowadays, in 
                         Brazil, several networks composed by different types of sensors 
                         provide these measurements, including electromagnetic passive 
                         sensors which are capable of detecting the lightningproducing 
                         radiation. Advanced processing units collect these data, locate 
                         the lightning discharges, integrate all the information, and store 
                         them in high-capacity and high-performance databases. These data 
                         are then assimilated into the NWP models to improve the forecast 
                         of extreme weather events. The RaioSat project intends to detect, 
                         for the first time, intra-cloud and cloud-to-ground lightning 
                         flashes simultaneously, the so-called total lightning data, using 
                         an optical sensor and a VHF antenna onboard a CubeSat platform. A 
                         dense network of surface sensors that detect and locate total 
                         lightning data in Brazil, named the BrasilDAT dataset, will be 
                         used to validate the RaioSat data as a ground-truth reference. The 
                         RaioSat mission is expected to be in a LEO orbit at 650km and it 
                         will use a 3U-CubeSat aluminum frame (10x10x30cm) to accommodate 
                         the main platform and its payload. The main platform shall be 
                         solar and battery powered, have telemetry, commanding and 
                         housekeeping capabilities via an on-board computer, 3-axis 
                         attitude control and a GPS. The payload shall have a VHF passive 
                         antenna, ranging from 50 to 200MHz, and a spectral imaging camera 
                         (SIC) with high-performance image processing capacity and large 
                         data storage memory. SIC resolution shall be 2,048 x 1,536 pixels 
                         leading to a surface imaging of 80 m/pixel at 650km altitude. Also 
                         SIC shall have a spectral range from 700 to 900nm using a 
                         band-pass optical filter. Additionally, this paper also analyses 
                         upfront the stages of the space mission over the system life-cycle 
                         which consists basically of: (a) mission analysis, (b) life cycle 
                         analysis, (c) functional analysis, (d) design architecture 
                         analysis and, (e) concept of operations among others.",
