We propose a data-driven framework for simultaneous system identification and global linearization of both the Two-Body Problem and Circular Restricted Three-Body Problem via deep learning-based Koopman Theory, i. e., a framework that can identify the underlying dynamics and globally linearize it into a linear time-invariant (LTI) system.
