Abstract
Since many years the Group of Astrodynamics of University of Rome "La Sapienza" (GAUSS) established a fruitful collaboration with Keldysh Institute for Applied Mathematics of Russian Academy of Sciences in Moscow. The GAUSS established the UNISAT program achieving experience in design, manufacturing and operating in orbit microsatellites. This program starts in early nineties at School of Aerospace Engineering with the aim to design, realize and launch small educational satellites involving students, researchers and professor in a real space project. All the satellites were realized with terrestrial off-the-shelf components in order to keep low the costs and make them affordable for university budgets. In the framework of this program three satellites have already been launched (respectively in 2000, 2002 and 2004) from Baykonour Cosmodrome with DNEPR launch vehicle and a fourth satellite is ready to be launched. On the other hand the Keldysh Institute of Applied Mathematics with the industry achieved good experience in Hyperspectometer design and realization. Different experiences and knowledge found a common project in HypSat. HypSat is a project, supported from FILAS (Finanziaria laziale di sviluppo of the Lazio region), to design a microsatellite capable to monitoring natural disasters, (fires, Earthquakes,..). The HypSat bus will be designed and manufactured from GAUSS on the basis of its past experiences and it will board, as primary payload, an enhanced version of Hyperspectrometer developed by the Keldysh Institute of Applied Mathematics of RAS. The paper deals with the HypSat main subsystems design. Moreover a coverage analysis for Lazio region has been carried out and results are discussed, taking into account the effectiveness of expected access time with respect to different natural calamities and considering the possibility to use a constellation of satellites to reduce the gap time. The Hyperspectrometer is also deeply depicted giving relevance to its main capabilities and constraints and evaluating expected results in Earth disasters monitoring.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
