A flightpath guidance system and method is disclosed for using moving
waypoints for a curved route plan such as a Bezier curve. The actual
location of a vehicle and a leading target point along the path are used
to provide commanded guidance of the vehicle along the path and to
correct for disturbances from the intended route. Waypoints along the
path may be moving with respect to the reference frame in which the
vehicle is measured. Curved flightpath guidance using moving waypoints
may be used for aerial rendezvous and refueling, multiple vehicle
applications such as formation flying and battlefield formation grouping,
and carrier landing. Further application includes air traffic control and
commercial flight guidance systems.
