Contents I. Introduction
Space debris monitoring is usually performed by a variety of different techniques and instrumentation, such as radar and laser ranging and optical observations by means of groundbased telescopes. On this purpose, optical observation is usually exploited for improving the precision of satellite orbit determination. The observations can be scheduled for surveillance tasks, in order to identify and track new orbital debris, or for tracking known objects and improving their position estimation. The orbit and position estimation of a satellite or a debris is achieved by performing astrometric measurements on the images acquired by the telescopes [1]. The data analysis mainly relies on the determination of the observed object celestial coordinates. These are determined by recognizing the background stellar field in the images by comparison with stellar catalogues [2]. The integration of a larger multiplicity of data (e.g. acquired with a telescope network dislocated over a larger area, or by a single telescope over a longer observation campaign) allow to improve the orbit determination of the tracked orbital debris.
