                                        KalmanFilter<MeasurementDecorator> filter,
                                        List<ObservedMeasurement<?>> observedMeasurements,
                                        AbsoluteDate referenceDate)

Simple constructor.

Parameters:

model - semi-analytical kalman model

filter - kalman filter instance

observedMeasurements - list of observed measurements

referenceDate - reference date

Method Detail

init

public void init(SpacecraftState s0,
                 AbsoluteDate t)

Initialize step handler at the start of a propagation.

This method is called once at the start of the propagation. It may be used by the step handler to initialize some internal data if needed.

The default method does nothing

Specified by:

init in interface OrekitStepHandler

Parameters:

s0 - initial state

t - target time for the integration

handleStep

public void handleStep(OrekitStepInterpolator interpolator)

Handle the current step.

Specified by:

handleStep in interface OrekitStepHandler

Parameters:

interpolator - interpolator set up for the current step
