Accuracy analysis of different orbit catalogues through calibrated optical observations in LEO

Traditionally, different catalogues (TLEs, SP, CPF) have been used as reference for orbit propagation and observational ephemerides generation, to which different degrees of accuracy and reliability have been attributed.
This study aims, through the use of an optical sensor undergone iterative calibration adjustments, for the acquisition of an aleatory sample of objects measurements in LEO regimes, and the comparison and analysis with the positions generated from the different catalogues. Due to a fine calibration of the telescope sensor, observed positions are considered the ground truth, and discrepancies affecting the propagated orbits are shown and discussed for the different catalogues and the orbital characteristics.
