cr3bp

An almost fully automated MATLAB CR3BP library.

Halo orbit solver with modern Fortran

A computational toolkit for the Circular Restricted Three-Body Problem

Indirect optimization for energy-optimal Lyapunov-to-Lyapunov transfer using heteroclinic connection as initial guess.

Validated, Python-native toolkit for CR3BP / cislunar mission design and trans-Neptunian-object discovery. Standard gravity, real DE440 ephemerides, cross-validated against NASA GMAT.

Low-energy Earth–Moon transfer design via invariant manifolds of CR3BP halo orbits. Differential correction, pseudo-arclength continuation, Poincaré section intersection search, and ΔV budget. Python + LaTeX paper.

High-performance Rust astrodynamics engine for Near-Rectilinear Halo Orbit (NRHO) simulations, featuring CR3BP physics and orbital rendezvous.

Multiple-shooting design of impulsive transfers between L1/L2 Lyapunov orbits in the Earth-Moon CR3BP, using invariant manifold theory and Poincaré section analysis to construct low-cost initial guesses.

This project has codes available for construction of lyapunov orbit and their invariant manifolds, and hence finding the intitial conditions for certain trajectories in non-dimensionalized 3 body problem. This projects is carried out to better understand the three-body dynamics.

Code for CR3BP project. Includes all figures + raw code.
