This paper aims to provide a detailed description of the problems concerning the radiation environment faced while designing a microsatellite at the University of Rome. Although main features of the microsatellite, as well as the environment characteristics expected in candidate orbits are detailed, emphasis is given to expose a generally appropriate procedure for this class of spacecraft. The sector...
Orbital break-ups produce a large number of fragments, which constitute an obvious hazard for other satellites in nearby orbits. Of these fragments, many are too small to be detected by ground-based facilities: this leads to the need for mathematical modelling as a tool for adequate risk analysis. In this paper an average spatial density model is presented. It is based on the Gauss analogy and,...
