Orbital Lifetime Analyses of Pico- and Nano-Satellites

摘要: In recent years, orbital debris has been a growing concern for the space industry due to its potential risk of causing collisions. Several agencies and organizations, such as National Aeronautics Space Administration (NASA), United Nations Committee on Peaceful Uses Outer (UNCOPUOS), have involved in studying developing mitigation guidelines. 2004, Federal Communications Commission (FCC) began requiring plan all non-government States radio communication satellites be launched into orbit. Orbital lifetime analysis satellite is important development complying with Factors that must taken consideration include environmental perturbations, solar radiation pressure, Earth?s oblateness, atmospheric drag. Other factors affect prediction are satellite's physical properties. this research, these perturbations their effects lifetime, Earth-orbiting satellites, were investigated. study, lifetimes determined using Lifetime tool Analytical Graphics? Satellite Tool Kit (STK) software, focusing pico- nano-satellites. The focus two classes perceived rapid growth difficulty adhering FCC requirements mitigation. effect cycle different density models also explored during analyses. results indicate pico-satellites can significantly reduced by increasing drag area. For instance, changing area 1-kg from 0.01 0.1 meters squared decreased 22 3 an 86% reduction. At 600 km above surface, areas had minimum lifetimes during years highest activity. Our implies passive de-orbiting devices chutes effective addressing Meanwhile, nano-satellites used our study between 11 28 kg, 0.08 0.2 squared, which led centuries when at 750 altitude. Values additions needed fulfill 25 year requirement set FCC. ( en )
