This branch is the special branch containing the modifications needed for the Orekit Python Wrapper.

An accurate and efficient core layer for space flight dynamics applications

Orekit is a low level space dynamics library written in Java. Orekit is designed to be easily used in very different contexts, from quick studies up to critical operations. As a library, Orekit provides basic elements (orbits, dates, attitude, frames, ...) and various algorithms to handle them (conversions, propagations, pointing, events detection, orbit determination ...).
