Class BodyCenterPointing

  • All Implemented Interfaces:
    AttitudeProvider

    public class BodyCenterPointing
    extends GroundPointing
    This class handles body center pointing attitude provider.

    This class represents the attitude provider where the satellite z axis is pointing to the body frame center.

    The object BodyCenterPointing is guaranteed to be immutable.
