getDate
public FieldAbsoluteDate<T> getDate()
Get the date.- Specified by:
getDate
in interfaceFieldTimeStamped<T extends CalculusFieldElement<T>>
- Returns:
- date attached to the object
-
shiftedBy
public TimeStampedFieldPVCoordinates<T> shiftedBy(double dt)
Get a time-shifted state.The state can be slightly shifted to close dates. This shift is based on a simple linear model. It is not intended as a replacement for proper orbit propagation (it is not even Keplerian!) but should be sufficient for either small time shifts or coarse accuracy.
- Specified by:
shiftedBy
in interfaceTimeShiftable<T extends CalculusFieldElement<T>>
- Overrides:
shiftedBy
in classFieldPVCoordinates<T extends CalculusFieldElement<T>>
- Parameters:
dt
- time shift in seconds- Returns:
- a new state, shifted with respect to the instance (which is immutable)
-
shiftedBy
public TimeStampedFieldPVCoordinates<T> shiftedBy(T dt)
Get a time-shifted state.The state can be slightly shifted to close dates. This shift is based on a simple linear model. It is not intended as a replacement for proper orbit propagation (it is not even Keplerian!) but should be sufficient for either small time shifts or coarse accuracy.
