The mobile air platform contains a container 1, the design of which is adapted for transportation in the body of a pickup truck. This is ensured by the shape of the container having a ledge above the pickup cab and ledges above the sides of the body. This form also allows transportation in the back of a truck and on a car trailer. For the possibility of prompt dismantling from the car and installation on the car, the container is equipped with jacks 2 and quick-release fastening devices. Quick-release fasteners are eyelets 3 and lanyards 4. Another option for quick-release fastening devices can be eyes and straps for securing cargo equipped with a ratchet mechanism. The mobile take-off and landing module can be used in autonomous mode, both with and without a car. For quick dismantling from the car, the lanyards or belts are loosened and removed from the eyelets. Next, the container is lifted with the help of jacks, and the car drives out from under it. For installation on a vehicle, the operations are carried out in reverse order. When using a container with a car without prompt dismantling, jacks, quick-release fasteners and these operations are not required.

A runway platform 5 is installed in the container for takeoff and landing of the UAV 6 connected to the ground part by a cable-cable 7.

The landing platform includes a base 8 and a frame 9. A landing pad 10 is installed on the frame 9. The frame with the landing pad is extended by means of a gear motor 11 by means of a rack-and-pinion transmission.

The cover of the container opening 12 is installed on the frame. The cover is equipped with seals 13 along the contour and is fixed in such a way that, with the landing platform fully extended, the opening cover fits snugly against the container opening with the container door open. In the cover of the opening of the container, there is a hole 14 for the cable-rope, which is closed with brush seals 15, which protect against drafts and dust ingress. Also, the cover of the container opening is equipped with visors 16, which provide protection from atmospheric precipitation of the hole for the cable-rope and the lower part of the container opening.

To ensure the operability of all systems of the mobile air platform at high values of negative ambient temperatures, the container can be additionally equipped with an autonomous heater. In conjunction with the cover of the container opening, which provides protection from atmospheric precipitation, dust and drafts, pre-heating is provided and the temperature inside the container is maintained suitable for stable operation of the equipment.

An automated cable layer 17 is mounted on the retractable frame. The cable layer is located behind the opening cover, and the cable-rope passes through the hole, which is closed with brush seals, thus the automated cable layer is protected from external influencing factors. During operation, when the UAV is in the air, the power to the UAV and the payload is continuously supplied through the cable from the power supply system. The power supply system can operate from an external network, and in the absence of such, from a generator, which can also be installed in a container.

The proposed invention allows to achieve a technical result due to the following:

- the cover of the container opening, fixed on the retractable frame, provides improved protection of the product from external influencing factors when the landing site is extended, when the UAV is in the air;

- landing platform, which has the shape of a grid, ensures the safety and reliability of landing, as well as the exclusion of snow, foliage and dirt from entering the container;

- a container with a ledge above the car cabin and ledges above the sides of the body, which can be equipped with jacks and quick-release fastening devices, expands the functionality to provide the possibility of prompt dismantling from the car and mounting on the car in order to be able to use it offline without a car.

The operation of the mobile air platform is carried out in the following order.

Upon arrival at the deployment site, if such a need arises, the container is unloaded from a vehicle or trailer. To do this, the lanyards or belts for fastening the container 4 are loosened and removed from the eyelets 3, with the help of jacks the container is lifted above the car, avoiding distortions. Next, the vehicle drives out from under the container. If there is no need to unload the container, the specified actions are not performed.

Next, the power supply system is connected to the external network; if this is not possible, the generator is started.

After opening the container door, the operator from the control panel gives a command to extend the frame 9 with the landing pad 10. The motor-reducer 11 extends the landing pad at full speed, until the limit switch of the open position is activated. The position of the limit switch is set in such a way that the cover of the container opening 12, with the landing pad fully extended, is firmly pressed against the container wall and closes the container opening.

UAV 6 is installed on the landing site, to which cable-rope 7 is connected, laid on an automated cable-layer 17. The cable-layer is located behind the cover of the container opening, and the cable-rope passes through the hole closed by brush seals 15.

At the command of the operator, the UAV takes off to the required height and the UAV switches to the automatic mode of holding the altitude and coordinates. The cable layer unwinds during the takeoff of the cable-rope on commands from the automated control system, which makes decisions based on the readings of the cable tension sensor mounted on the retractable frame. In the mode of holding the height and coordinates, the cable layer automatically maintains the necessary tension of the cable-rope so that the latter does not sag or get tangled.

The cable-rope continuously supplies power to the motors of the UAV, as well as charging the backup batteries of the UAV, which, in the event of a power failure, will provide an emergency landing. In addition, the cable-rope provides power to the payload and data transmission if necessary.

Upon completion of work, the operator gives a command to land and the UAV lands on the landing site in automatic mode. At the same time, the cable layer automatically winds the cable rope. After that, the landing pad slides into the container until the limit switch of the closed position is activated, the container door closes, the generator or the external network is turned off. Loading on the car (if necessary).
