The eos3d-mpl library is a lightweight orbital mechanics calculation and visualization suite based on matplotlib. It includes orbit visualization, SPACETRACK Two-Line Element retrieval and current satellite position visualization, Solar System orbits and planetary position visualizations and real-time n-body simulations.
eos3d-mpl runs on Python3 versions starting from 3.4 and requires the following libraries for full functioning:
matplotlibscipynumpypandaspycurl(otional for getTLE)python-sgp4(optional for SGP4 propagation)
For quick installation use the following pip command:
$ pip install matplotlib pandas scipy numpy pycurl sgp4For starters, a simple orbit can be created using the following command:
from eos3dmpl import eos_core
# Initialize Eos class and viewport
eos = eos_core.Eos()
eos.view_init()
# Add orbit with semi-major axis of 10000 km, eccentricy of 0.2 and inclination of 30 degrees
eos.orbit(a=10000,e=0.2,i=30)
# Add previous orbit to viewport and view result
eos.kepler()
eos.view()Many more examples can be found in the attached Jupyter notebook (WIP).
For more in-depth information on eos3d-mpl, be sure to check out the docs/documentation.pdf file (still a work-in-progress).
NOTE: The documentation refers to eos3d-mpl as EOS, as it was envisioned to be the final form of the library at the time. Now, however, an OpenGL python3-based implementation of the library, with extended capabilities, is being developed. Its name is slated to be EOS3D.
An exhaustive documentation page is planned in the future.
