pystrodynamics is a spacecraft dynamics library and simulation framework in Python. It is intended to work akin to NASA's GMAT or Orekit, but by virtue of being written in Python, is more accessible to a wider range of users who can more easily extend and modify it to their needs.
pystrodynamics is a library built on the shoulders of others. Heavily used are Skyfield and astropy, alongside the ever-present numpy and scipy libraries.
