public class TargetPointing extends GroundPointing
This class represents the attitude provider where the satellite z axis is pointing to a ground point target.
The target position is defined in a body frame specified by the user. It is important to make sure this frame is consistent.
The object TargetPointing
is guaranteed to be immutable.
