Abstract
  • We present the results of a large scale simulation, reproducing the behaviour of a data centre for the build-up and maintenance of a complete catalogue of space debris in the upper part of the low Earth orbits region (LEO). The purpose is to determine the performances of a network of advanced optical sensors, through the use of the newest orbit determination algorithms developed by the Department of Mathematics of Pisa (DM). Such a network has been proposed to ESA in the Space Situational Awareness (SSA) framework by Carlo Gavazzi Space SpA (CGS), Istituto Nazionale di Astrofisica (INAF), DM and Istituto di Scienza e Tecnologie dell'Informazione (ISTI-CNR). The conclusion is that it is possible to use a network of optical sensors to build up a catalogue containing more than 98% of the objects with perigee height between 1100 and 2000 km, which would be observable by a radar system as envisaged for the ESA SSA project. It is also possible to maintain such a catalogue within the accuracy requirements motivated by collision avoidance, and to detect catastrophic fragmentation events. However, such results depend upon specific assumptions on the sensor and on the software technologies. (literal)
