      • dependsOnPositionOnly

        public boolean dependsOnPositionOnly()
        Check if force model depends on position only at a given, fixed date.
        Specified by:
        dependsOnPositionOnly in interface ForceModel
        Returns:
        true if force model depends on position only, false if it depends on velocity, either directly or due to a dependency on attitude
