Method Summary

Modifier and Type	Method	Description
default void	finish(SpacecraftState finalState)	Method called at end of propagation.
Vector3D	getImpulse(SpacecraftState state, boolean isForward)	Method returning the impulse to be applied.

Method Details

getImpulse

Vector3D getImpulse(SpacecraftState state,
 boolean isForward)

Method returning the impulse to be applied.

Parameters:

state - state before the maneuver is applied if isForward is true, after otherwise

isForward - flag on propagation direction

Returns:

impulse in satellite's frame

init

default void init(SpacecraftState initialState,
 AbsoluteDate targetDate)

Method called at start of propagation.

Parameters:

initialState - state at start of propagation

targetDate - target end date

finish

default void finish(SpacecraftState finalState)

Method called at end of propagation.

Parameters:

finalState - state at end of propagation

of

static ImpulseProvider of(Vector3D forwardImpulse)

Get a provider returning a given vector for forward propagation and its opposite for backward. The attitude comes from the state directly.

Parameters:

forwardImpulse - forward impulse vector

Returns:

constant provider
