Check location Example  One

The unmanned aerial vehicle may identify the location by the plurality of location information providing units 110 located at predetermined intervals. Here's how to check the location:

Each location information providing unit 110 transmits a signal including individual ID information. The unmanned aerial vehicle receives a signal from each location information providing unit 110, measures the strength of the signal, and calculates a position of the main body based on the strength of the signal.

When the strength of a radio signal propagates in space, the signal strength decreases with distance. The strength of the decreasing signal depends on the frequency characteristics and the space, which is known information.

The unmanned aerial vehicle calculates the position of the unmanned aerial vehicle by measuring the plurality of input signal strengths based on the signal strengths by measuring the distance of the inputted DB in advance, and calculating the position of the unmanned aerial vehicle. .

When the position information providing apparatus 100 is installed in only one axis, the correct position can be confirmed with respect to the installed axis. However, for the other axis, each position information providing unit 110 is based on the strength of the largest signal. The relative position of the other axis can be known.

That is, Example 1 may be a method for the unmanned aerial vehicle to know its location.

In addition, the unmanned aerial vehicle includes a separate communication device, and has a function of transmitting its own location to the outside, and can control the unmanned aerial vehicle or transmit and receive data using the communication device. .

Location Example  2

There is also an embodiment in which the unmanned aerial vehicle can transmit and receive simultaneously instead of receiving. When the unmanned aerial vehicle transmits a signal, the location information providing apparatus 100 may receive the signal and check the position of the unmanned aerial vehicle based on the timing of the signal.

In order to implement such a function, calculation may be performed in the location information providing unit 120, and a plurality of aircraft ID receivers (not shown) may receive signals, and calculate the strength of the signal in a separate device. You can check the location of.

In addition to receiving only the aircraft ID receiver (not shown), it may be a method of transmitting a signal again. When the dominant vehicle is operated as in the second embodiment, when the unmanned aerial vehicle performs a full autonomous flight without any person's control or adjustment in a predetermined space, the unmanned aerial vehicle is directly or indirectly used by the location information providing device. There is an advantage to monitor the position of.

That is, the second embodiment is a method that can know the position of the unmanned aerial vehicle using the location information providing apparatus 100.

The signal used to identify the position may be a continuous signal or may be a pulse type signal.

Each embodiment in the plurality of embodiments of the present invention may be carried out independently, each embodiment may be carried out in combination. That is, the first embodiment (method of confirming the position of the unmanned aerial vehicle) and the second embodiment (method of confirming the position of the unmanned aerial vehicle) may be performed simultaneously or individually, and each of the embodiments Functions can also be performed sequentially.

Although the present invention has been described by specific embodiments such as specific components and the like, but the embodiments and the drawings are provided to assist in a more general understanding of the present invention, the present invention is not limited to the above embodiments. For those skilled in the art, various modifications and variations can be made from these descriptions.
