A guidance system for unmanned air vehicles

Unmanned air vehicle system is composed of control station, payload, air vehicle, navigation and communication subsystems. Among these, navigation and guidance are most important subsystems. By using the lateral and vertical navigation guidance systems, the planned flight transition of the UAV can be realized from departure waypoint to the target. In this study, the air vehicle which deviates from the route due to the wind and other aerodynamic conditions is placed to the required route in the original flight plan and necessary softening is provided for the rotations of the air vehicle.
