S.A.L.U.S 1U COTS CubeSat Mission

Due to the increase of greenhouse gas emissions caused by the rapid expansion of human industrialization over the past century, Mission S.A.L.U.S (Surrounding Atmospheric Logging Utilization Satellites), as a technology demonstration, aims to gather data on greenhouse gases, solar radiation, and magnetic fields to monitor climate change and help deduce new strategies to decrease the rate of global warming. To achieve its purpose, four 1U COTS (commercial-off-the-shelf) CubeSats (GreenSat, SolarSat, DataSat, and MagnoSat) are designed, assembled, and integrated with Raspberry Pi 4 Models and BerryGPS-IMUs equipped with accelerometers, gyroscopes, barometers, magnetometers, temperature sensors, and global positioning systems. The GreenSat monitors the greenhouse gas concentrations in the thermosphere; the SolarSat monitors the solar radiation inputted into Earths atmosphere by the Sun. The MagnoSat monitors atmospheric pressure and magnetic fields to deduce climate changes in Earths upper atmosphere; the DataSat receives data and information collected by the other three CubeSats and sends the data to ground control. Each CubeSat has five main subsections for the electronics: command and data handling (CDH), communication (COMMS), altitude determination and control (ADCS), electrical power system (EPS), and the corresponding sensors. All four CubeSats sensors are tested on the ground and preliminary results from data analysis will help determine feasibility of the mission, as well as the best sensors to use. Therefore, this mission lays the groundwork for a multitude of future COTS CubeSat missions involving the collection of data related to Climate Change.
