2022-10-25  Orekit 11.3 released

The Orekit team is pleased to announce the release of Orekit version 11.3.

This is a minor version, including both new features and bug fixes.

Highlights in the 11.3 release are:

• The unscented Kalman filter (numerical version),
• The semi-analytical unscented Kalman filter (DSST version),
• A new PVCoordinatesProvider modelling waypoints on an ellipsoid following a loxodrome (commonly, a rhum bline),
• A new method to compute hyperbolic anomaly based on Gooding and Odell algorithm,
• A new built-in additional state for covariance propagation (linear method based on the state transition matrix computation),
• With a new state covariance object allowing covariance transformation between frames and orbit types,
• The extrapolation of the state covariance matrix using a Keplerian model,
• And the ability to extrapolate a state covariance matrix using a Keplerian model,
• The migration of all JUnit tests from JUnit 4 to JUnit 5,
• The ability to estimate measurement parameters (station position or clock biases) from an ephemeris,
• New methods to convert from/to Orekit frames and CCSDS frames,
• Improvements of CCSDS CDM (Collision Data Message) parsers,
• Improvements in date handling and aggregate bounded propagators,
• Several bug fixes and documentation improvements.

This release also include a new tutorial for maneuvers’ thrusts and dates estimation.

This version depends on Hipparchus 2.3.
