An unmanned aerial vehicles take-off system may include at least one winch, at least one towline, at least one dolly on which at least one aircraft is mounted, and at least one battery of the at least one winch. At least one micro-controller unit is connected to the at least one winch, wherein the at least one microcontroller unit is configured to control the activation/deactivation of the at least one winch. An unmanned aerial vehicle take-off method is also disclosed that includes operating the at least one winch by means of at least one microcontroller unit connected to said at least one winch.

A method and apparatus for launching unmanned air vehicles (UAVs) includes supporting the unmanned air vehicle on a surface vehicle, such as a dolly cart, for riding along a surface such as ground or water. A towline is connected to the surface vehicle and the towline is pulled to force the unmanned air vehicle in a forward direction at a speed sufficient for take-off. The towline may be pulled by a winch system. In some embodiments the UAV is positioned with a nose down angle on the surface vehicle. The nose down angle permits overspeed of the UAV and cart as it is pulled along the ground, as well as controlled take-off.
