A Python satellite astrodynamics library meant for use in spacecraft guidance, navigation, and control work.

Current high-fidelity satellite GNC modeling software generally runs into the following pitfalls:

1. It is commercially licensed and closed-source code, making it difficult, if not impossible, to be used by hobbyists and academic researchers.
2. Large open-source projects with a steep learning curve making correct use for small projects difficult
3. Out-dated API leading making it hard to incorporate into modern projects.
4. Hard to get up and running with.

These challenges make it an unfortunately common occurance that spacecraft engineers and researchers will frequently reimplement common astrodynamics libraries for each new project or analysis.

With these deficienties in mind, brahe aims to provide a open-source, MIT-licensed, high fidelity astrodynamics toolbox to help make it easy to perform high-quality simulation and analysis of satellite attitude and orbit dynamics.

This is the sister repository of SatelliteDynamics.jl, a Julia language implementation of the same functionality. In general, the functionality supported by each repository is interchangeable. The main differences between the repositories come down to the underlying repositories. The Julia implementation tends to be more performant, while the Python implementation can take advantage of the larger package ecosystem.

The documentation for the package can be found here: https://duncaneddy.github.io/brahe/

This package is distributed from PyPi, and can be installed simply with:

pip3 install brahe

The brahe package is licensed and distributed under the MIT License to encourage usage and to make it easy to integrate with other tools.

The only thing asked is that if you do use the package in your work, or appreciate the project, either send a message or star the project. Knowing that the project is being actively used is a large motivator for continued development.

If you use brahe for your research or work, I'd love to know about it. Please message me, or let me know. If there are
