About SemPy

SEMpy is an open source Python 3 library (AGPLv3) providing user-friendly tools for advanced astrodynamics studies and mission analysis in non-Keplerian environments. These include (but are not limited to) orbit construction in Circular Restricted Three-Body Problem environments, numerical integration and trajectory design in High-Fidelity environments, Rendezvous operations in non -Keplerian dynamics, Lowthrust trajectory design ...

SemPy is maintained by the Space Advanced Concepts Laboratory (SacLab) of ISAE-Supaero (Toulouse, France). It is a community-driven project, hosted on Gitlab.
