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.",
