The Vehicle Body Frame is defined as the right-hand orthogonal coordinate system with
its origin at the vehicle’s centreline. Its three axis are referenced to the vehicle’s vertical
and horizontal planes where the:
 X-axis is parallel to the horizontal plane and extends towards the front - called the
vehicle longitudinal axis any rotation about this axis is called ‘roll’.
 Y-axis is parallel to the horizontal plane and extends towards the starboard (right)
side - called the vehicle lateral axis, any rotation about this axis is called ‘pitch’.
