OREKIT

Orekit aims at providing accurate and efficient low level components for the development of flight dynamics applications. It 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…)... As a a low level library, Orekit aims at being used in very different contexts which cannot be foreseen, from quick studies up to critical operations.
