The OpenAstrodynamics Intiative

OpenAstrodynamics is a collaboration between open source astrodynamics and space engineering projects to share resources, ideas, and to improve code.

Core Principles

We believe in…

  • Interoperability through open standards and protocols
  • Sharing validated algorithms
  • Contributing test cases and reference scenarios
  • Diversity in implementations and technologies


  • Astrodynamics.jl is an MPLv2-licensed framework for building astrodynamics applications in Julia.
  • openastro is a collection of C++ libraries for astrodynamics and space engineering.
  • poliastro is a python package for Astrodynamics and Orbital Mechanics problems, such as orbital elements conversion, orbital propagation, plotting, planetary ephemerides computation, and more.
