Package org.orekit.estimation.sequential

The sequential package provides an implementation of a Kalman Filter engine to perform an orbit determination.

Users will typically create one instance of this object, register all observation data as measurements with their included modifiers, and run the kalman filter. For each processed measurement, a fully configured propagator will be available, as well as all estimated parameters individually.
