Interface FieldAbstractIntegratedPropagator.MainStateEquations<T extends RealFieldElement<T>>

Enclosing class:

FieldAbstractIntegratedPropagator<T extends RealFieldElement<T>>

public static interface FieldAbstractIntegratedPropagator.MainStateEquations<T extends RealFieldElement<T>>

Differential equations for the main state (orbit, attitude and mass).

Method Summary

Modifier and Type	Method and Description
T[]	computeDerivatives(FieldSpacecraftState<T> state) Compute differential equations for main state.
void	init(FieldSpacecraftState<T> initialState, FieldAbsoluteDate<T> target) Initialize the equations at the start of propagation.

Method Detail

init

void init(FieldSpacecraftState<T> initialState,
          FieldAbsoluteDate<T> target)
   throws OrekitException

Initialize the equations at the start of propagation. This method will be called before any calls to computeDerivatives(FieldSpacecraftState).

The default implementation of this method does nothing.

Parameters:

initialState - initial state information at the start of propagation.

target - date of propagation. Not equal to initialState.getDate().

Throws:

OrekitException - if there is an Orekit related error during initialization.

computeDerivatives

T[] computeDerivatives(FieldSpacecraftState<T> state)
                throws OrekitException

Compute differential equations for main state.

Parameters:

state - current state

Returns:

derivatives of main state

Throws:

OrekitException - if differentials cannot be computed
