WebDec 4, 2016 · The incompleteness of orbital propagation model can cause model errors during orbital propagation. If we can get the orbital true value at the initial time, model errors may bring about orbital propagation errors, refer to Fig. 2.4. The diffusion of initial errors and model errors may be coupled with each other. Orbit is a Python package for Bayesian time series forecasting and inference. It provides afamiliar and intuitive initialize-fit-predict interface for time series tasks, while utilizing probabilistic programming languages under the hood.
