Abstract For the on-orbit flight missions, the model of orbit prediction
is critical for the tasks with high accuracy requirement and limited computing resources of spacecraft. The precession-nutation model, as the main
part of extended orbit prediction, affects the efficiency and accuracy of
on-board operation. In this paper, the previous research about the conversion between the Geocentric Celestial Reference System and International
Terrestrial Reference System is briefly summarized, and a practical concise
precession-nutation model is proposed for coordinate transformation computation based on Celestial Intermediate Pole (CIP). The idea that simplifying
the CIP-based model with interpolation method is driven by characteristics of… More >
