Plyades: A Python Astrodynamics Library¶

Plyades is an MIT-licensed astrodynamics library written in Python. It aims to provide a comprehensive toolset for fast development of performant mission analysis applications. The API provides powerful high-level objects for pythonic ease-of-use while the low-level functional building blocks can also be used independently.

Warning

This library is currently a proof of concept and has not been validated or used within an operational context. As soon as this changes the validation results will be documented here.
