1.5 2019-05-06 This is a maintenance release, it includes only bug fixes.
1.4 2018-11-17 This is a maintenance release. The main changes since last version are the introduction of accessors for state transition matrix, Jacobian matrix H, innovation covariance matrix and Kalman gain in Kalman filters.
1.3 2018-05-08 This is the first release of the filtering module. The module features both Kalman filter for linear processes and Kalman filter for non-linear processes.

Release 1.8 – 2020-12-05

Type Changes By
No changes directly in this module. However, lower level Hipparchus modules did change, hence a new release was needed. luc

Release 1.5 – 2019-05-06

Type Changes By
Nullify corrected state after predict in abstract Kalman filter. Note that this affects only custom extensions of AbstractKalmanFilter because the implementations provided by Hipparchus (LinearKalmanFilter and ExtendedKalmanFilter) always call correction step after having called prediction step, so the nullified corrected state is reset properly at the end. This was initially reported as https://gitlab.orekit.org/orekit/orekit/issues/540. Thanks to Hao Peng. luc

Release 1.4 – 2018-11-17

Type Changes By
Added accessors for state transition matrix, Jacobian matrix H, innovation covariance matrix and Kalman gain in Kalman filters. GitHub: fixes #43. Fixes issues/43. luc

Release 1.3 – 2018-05-08

Type Changes By
Added linear and extended Kalman filters, with support for outliers rejection. Fixes issues/32. luc
