An accurate and efficient core layer for space flight dynamics applications
Orekit, a low level space dynamics library written in Java, has gained widespread recognition since it was released under an open source license in 2008.
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...).
Orekit is freely available both in source and binary formats, with all related documentation and tests.
Orekit is distributed under the Apache License version 2.0, a well known business-friendly license. This means anybody can use it to build any application, free or not. There are no strings attached to user code.
Airbus Defence and Space (ADS) uses Orekit in Quartz, its new generation flight dynamics software. In addition, ADS actively contributes to Orekit and is member of its Project Management Committee (PMC).
Orekit is used for various studies by the U.S. Naval Research Laboratory (NRL). In addition, the NRL actively contributes to Orekit and is member of its PMC.
Orekit has been successfully used during the real time monitoring of the rendez-vous phase between the Automated Transfer Vehicle (ATV) and the International Space Station (ISS) by the Centre National d'Études Spatiales (CNES) and the European Space Agency (ESA).
Orekit is used for several studies and ground systems developments by various industrial actors such as EUMETSAT.
Exotrail uses Orekit as a low-level astrodynamics layer for its mission analysis and constellation design software spacestudioTM, and its constellation operation software spacetowerTM.
Orekit has been in development since 2002 inside CS GROUP and is still used and maintained by its space dynamics experts. Several major actors of space research and industry are now involved into this project.
This project follows the Free and Open Source Software (FOSS) development best practices identified by the Core Infrastructure Initiative:
We do our best to provide you with a quality code:
The Orekit project is driven according to an open governance model, involving representatives from different space field actors in a Project Management Committee (PMC).
