Orekit is designed to be easily used in very different contexts, from\nquick studies up to critical operations. As a library, Orekit provides basic\nelements (orbits, dates, attitude, frames, ...) and various algorithms to\nhandle them (conversions, propagations, pointing, events detection, orbit determination ...).\n\n[![](http://img.shields.io/:license-apache-blue.svg)](http://www.apache.org/licenses/LICENSE-2.0.html)\n[![](https://sonar.orekit.org/api/project_badges/measure?project=orekit%3Aorekit\u0026metric=alert_status)](https://sonar.orekit.org/dashboard?id=orekit%3Aorekit)\n[![](https://sonar.orekit.org/api/project_badges/measure?project=orekit%3Aorekit\u0026metric=coverage)](https://sonar.orekit.org/dashboard?id=orekit%3Aorekit)\n[![DOI](https://zenodo.org/badge/DOI/10.5281/zenodo.7249096.svg)](https://doi.org/10.5281/zenodo.7249096)\n\n\n\n## Download\n\n### Official releases\n\n[Official Orekit releases](https://gitlab.orekit.org/orekit/orekit/-/releases)\nare available on our [Gitlab instance](https://gitlab.orekit.org/).
