The IITMSAT satellite is a student satellite that has been designed around a specialised payload, called SPEED.
Space based Proton Electron Energy Detector (SPEED) is a scintillator detector system for measuring the energy spectrum, background flux, and fluctuations in the flux of protons and electrons in the upper ionosphere. The detector is being developed as a payload for IITMSAT. The study made using the detector will help verify and improve current trapped particle radiation models and analyze the dynamic nature of the radiation belts.
The particle environment in space changes continuously and is affected by various phenomena including solar flares, magnetic field fluctuations, etc. A record of this information is important for understanding the effects such phenomena may have on the dynamic nature of the belt. Understanding the dynamical nature of the belts is crucial for the success of Low Earth Orbiting systems and manned space missions. Scientists involved in areas of research such as space radiation, solar physics, ionosphere and atmospheric studies, and geo-magnetism will directly benefit from the data gathered by SPEED.
