OREKIT

An accurate and efficient core layer for space flight dynamics applications

Orekit 10.3.1 released, get it!


WHAT IS IT?

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.


SPACE DYNAMICS LIBRARY

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,
...).


FREE (OPEN SOURCE) SOFTWARE

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.


WHO IS USING IT?

 * CS GROUP develops ORaaS (Orekit-as-a-Service), an Orekit-based web service
   including demos, tools and a REST API to access services such as orbit
   determination.

 * 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.

 * Swedish Space Corporation (SSC) uses Orekit for various studies. SSC has
   created and maintains the Orekit Python wrapper for years. SSC is member of
   Orekit PMC.

 * Thales Alenia Space uses Orekit for the flight dynamics software of its new
   geostationary electric platform SpaceBus Neo (within ESA's NEOSAT program)
   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.

 * You may discover other usages of Orekit in the presentations made by several
   space sector actors during the Orekit Day 2017 and Orekit Day 2019.


WHO IS BEHIND IT?


DEVELOPMENT

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:




OPEN GOVERNANCE

The Orekit project is driven according to an open governance model, involving
representatives from different space field actors in a Project Management
Committee (PMC).
