Releases: CS-SI/Orekit
9.1
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.
Several bugs have been fixed.
This version depends on Hipparchus 1.2.
9.0.1
8.0.1
7.2.1
9.0
Version 9.0 is a major release of Orekit. It introduces several new features and bug fixes. New features introduced in version 9.0 are:
- Taylor algebra propagation (for high order uncertainties propagation or very fast Monte-Carlo studies)
- multi-satellites orbit determination
- parallel multi-satellites propagation
- parametric accelerations (polynomial and harmonic)
- turn-around measurements
- inter-satellite range measurements
- rigth ascension/declination measurements
- Antenna Phase Center measurements modifiers
- EOP estimation in precise orbit determination
- orbit to attitude coupling in partial derivatives
- parsing of CCSDS Tracking Data Messages
- parsing of university of Bern Astronomical Institute files for Klobuchar coefficients
- ITRF 2014
- preservation of non-Keplerian orbits derivatives
- JB2008 atmosphere model
- NRL MSISE 2000 atmosphere model
- boolean combination of events detectors
- ephemeris writer
- speed improvements when tens of thousands of measurements are used in orbit determination
- Danish translations
Several bugs have been fixed.
This version depends on Hipparchus 1.1 released in March 2017.
8.0
Version 8.0 is a major release of Orekit. It introduces several new features and bug fixes as well as a major dependency change. New features introduced in version 8.0 are:
- orbit determination,
- specialized propagator for GPS satellites based on SEM or YUMA files,
- computation of Dilution Of Precision,
- new angular separation event detector.
Several bugs have been fixed.
A major change introduced with version 8.0 is the switch from Apache Commons Math to Hipparchus as the mathematical library, which also implied switching from Java 6 to Java 8.
7.2
Version 7.2 is a minor release of Orekit. It introduces several new features and bug fixes. The most important features introduced in version 7.2 are handling of GLONASS and QZSS time scales, support for local time zones according to ISO-8601 standard, and finer tuning of short period terms in DSST propagator.
Version 7.2 depends on version 3.6.1 of Apache Commons Math, which also fixes a bug related to close events detection.
