Package org.orekit.propagation.sampling

Interface FieldOrekitStepInterpolator<T extends CalculusFieldElement<T>>

Type Parameters:

T - type of the field elements

All Superinterfaces:

FieldPVCoordinatesProvider<T>

public interface FieldOrekitStepInterpolator<T extends CalculusFieldElement<T>>
extends FieldPVCoordinatesProvider<T>

This interface is a space-dynamics aware step interpolator.

It mirrors the StepInterpolator interface from commons-math but provides a space-dynamics interface to the methods.

Method Details

getPreviousState

FieldSpacecraftState<T> getPreviousState()

Get the state at previous grid point date.

Returns:

state at previous grid point date

getCurrentState

FieldSpacecraftState<T> getCurrentState()

Get the state at previous grid point date.

Returns:

state at previous grid point date

getInterpolatedState

FieldSpacecraftState<T> getInterpolatedState(FieldAbsoluteDate<T> date)

Get the state at interpolated date.

Parameters:

date - date of the interpolated state

Returns:

state at interpolated date the date

isForward

boolean isForward()

Check is integration direction is forward in date.

Returns:

true if integration is forward in date

restrictStep

FieldOrekitStepInterpolator<T> restrictStep(FieldSpacecraftState<T> newPreviousState,
 FieldSpacecraftState<T> newCurrentState)

Create a new restricted version of the instance.

The instance is not changed at all.

Parameters:

newPreviousState - start of the restricted step

newCurrentState - end of the restricted step

Returns:

restricted version of the instance

Since:

11.0
