Orekit 9.2.0

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, ...).

Recent Releases

9.2.001 Jun 2018 08:16 minor feature: Version 9.2 is a minor release of Orekit. It introduces several new features and bug fixes. New features introduced in version 9.2 are Kalman filter for orbit determination, loading of RINEX, ANTEX and SP3 files, on-the-fly decompression of .Z files, code measurements, phase measurements, specific attitude laws (GPS, GLONASS, GALILEO, BEIDOU) with midnight/noon turns, possibility to use backward propagation in LS orbit determination, support for any ITRF version, attitude overriding in constant thrust maneuvers, filtering mechanism to insert specific decompression or deciphering algorithms during data loading frames for Lagrange L1 and L2 point for any two related celestial bodies. This version depends on Hipparchus 1.3.
9.1.018 Dec 2017 09:11 minor feature: Version 9.1 is a minor release of Orekit. It introduces a few new features and bug fixes. New features introduced in version 9.1 are some frames in OEM parser, retrieval of EOP from frames, ground station displacements modelling (both displacements due to tides and displacements due to ocean loading), retrieval of covariance matrix in orbit determination. This version depends on Hipparchus 1.2.
9.0.108 Nov 2017 09:49 security: The Orekit team has released version 7.2.1, 8.0.1, and 9.0.1 of Orekit to fix a security vulnerability. Orekit versions 5.0, 6.0, 6.1, 7.0, 7.1, 7.2, 8.0, and 9.0 are vulnerable to a XML External Entity (XXE) attack when loading XML format Earth Orientation Parameters (EOP) or Tracking Data Messages (TDM) from an untrusted source, possibly resulting in denial of service or data theft. The Orekit team recommends that all users update to one of the newly released versions as quickly as possible. Security fix versions were not released for the 5.x and 6.x series because these versions are considered to be obsolete. If you cannot upgrade from these obsolete version please email the Orekit developers (orekit-developers@orekit.org) to discuss creating a security fix release. A CVE number has been requested.
