poliastro is an open source pure Python package dedicated to problems arising in Astrodynamics and Orbital Mechanics, such as orbit propagation, solution of the Lambert’s problem, conversion between position and velocity vectors and classical orbital elements and orbit plotting, focusing on interplanetary applications. It is released under the MIT license.

Examples

mybinder

In the examples directory you can find several Jupyter notebooks with specific applications of poliastro. You can launch a cloud Jupyter server using binder to edit the notebooks without installing anything. Try it out!

Requirements

poliastro requires the following Python packages:

  • NumPy, for basic numerical routines
  • Astropy, for physical units and time handling
  • numba (optional), for accelerating the code
  • jplephem, for the planetary ephemerides using SPICE kernels
  • matplotlib, for orbit plotting
  • plotly, for 2D and 3D interactive orbit plotting
  • SciPy, for root finding and numerical propagation

poliastro is tested on Linux, OS X and Windows on Python 3.6, 3.7 and 3.8 against latest NumPy.

FAQ

What’s up with the name?

poliastro comes from Polimi, which is the shortened name of the Politecnico di Milano, the Italian university where I was studying while writing this software. It’s my tiny tribute to a place I came to love. Grazie mille!

Can I do <insert awesome thing> with poliastro?

poliastro is focused on interplanetary applications. This has two consequences:

  • It tries to be more general than other Flight Dynamics core libraries more focused on Earth satellites (see Related software for a brief list), allowing the algorithms to work also for orbits around non-Earth bodies.
  • It leaves out certain features that would be too Earth-specific, such as TLE reading, SGP4 propagation, groundtrack plotting and others.

What’s the future of the project?

poliastro is actively maintained and receiving an influx of new contributors thanks to the generous sponsorship of Google and the European Space Agency. The best way to get an idea of the roadmap is to see the Milestones of the project.
