ABSTRACT
Space Weather profiling is the concept of modeling the changing environmental conditions in near-Earth space in the form of a mathematical model. Solar Activity, Inconsistent variations in radiation level, total electron count, water vapor profiles are some of the parameters measured using the on board devices of the micro-satellite that we shall be discussing here. The module consists of a Geiger Muller Tube/counter, a Radiometric IR camera and a GPS Receiver. The Geiger Muller Tube takes radiation readings when there is ionizing radiation incident on its mica window. The radiation reading is in the form of dose rates. The second device i.e. the Radiometric IR Camera takes a thermal image of the temperature fluctuations because of this ionizing radiation. The data from these two devices are then plotted onto the same map to give 3D Predictive Model of radiation which can then be extrapolated depending on our purpose. The GPS receiver takes in the signal from the GPS satellite which passes through the atmospheric limb path and it’s bending takes place due to the various factors like change in pressure, temperature, water vapor, TEC. The angle of bend can be measured to obtain the profile of these factors causing the bend by using Abel transforms and other mathematical models. The data collected from the
