Methods of calculating low-orbit satellite visibility statistics

Orbit models are typically propagated in time and space using special perturbation methods. This is performed by first modeling the orbit as a Keplerian orbit. Then perturbations are added to the model to account for the various perturbations that affect the orbit. Special perturbations can be applied to any problem in celestial mechanics, as it is not limited to cases where the perturbing forces are small. Special perturbation methods are the basis of the most accurate machine-gen… WebJul 18, 2024 · Predicting the orbital displacement time interval involves two orbital methods, namely Cowell method and Encke method.
