  • Control Phase: The operation is divided into phases in which the UAV has a specific performance. Each of this phases is called a control phase.
  • Control Channel: It is each of the signals used to control a behaviour or action.
  • Control Mode: It is possible to make a manual control of the UAV by stick, assisted control and fully automatic control.
  • Actuator: It is a mechanic device to provide force to move or “act” another mechanical device.
