A disadvantage of the known system should be recognized as its complexity, as well as the high cost of its implementation due to the need to create new expensive nodes.

Also known (RU, patent 2117394) is a method and system for tracking a mobile device. When implementing the method, information about the initial location of this mobile device is generated, an information message about the initial location of this mobile device is transmitted from the mobile device, and an information message describing the border corresponding to the border of the territory under the relevant jurisdiction is received on the mobile device, when the mobile device is outside the border, after which the information message is transmitted eniya current location of the mobile unit. The known system comprises a mobile device and a control device, and a location sensor, a transceiver, a memory unit and a processor connected to a location sensor, a memory unit and a transceiver are introduced on the mobile device, and the control device contains a transceiver for exchanging data with the transceiver of the mobile device, block memory and a processor connected to the transceiver and to the control unit.

A disadvantage of the known technical solution should be recognized its scale, because it is able to work effectively only in large areas.

The technical problem solved by the proposed technical solution is to develop a universal system for monitoring the location of an object moving on the Earth’s surface.

The technical result obtained by the implementation of the proposed technical solution consists in reducing the cost of determining the location of a moving object while simplifying it, as well as simplifying the system used.

To achieve the technical result, it is proposed to use a method for determining the location of a moving object, characterized by the presence of a device placed on the object and containing a microprocessor connected to a power supply, as well as a transceiver unit whose output is connected to the antenna and the input to the microprocessor, wherein the specified microprocessor is configured to periodically generate a transmission command by a specified part of the transmitting unit of the specified part of the receiving unit uniquely identifiable and identifying the carrier object of the device, the call signal, the registration of the specified signal by at least one tower, a repeater, preferably GSM communication, followed by radio transmission to the base station of the operator, preferably GSM communication, followed by broadcasting the specified signal through the INTERNET network to users interested in determining the location of the specified object. When implementing the method, a person, an animal or a bird can be used as an object, as well as a moving or moving technical device (car, motorcycle, plane, watercraft, etc.). When a device is placed on a person, he, depending on the task to be solved, can be informed about it or not informed. In particular, when controlling the movement of a socially dangerous person, the placement of the device can be carried out without his knowledge. With an increase in the number of relay towers capable of detecting a pick-up signal transmitted by the device, the accuracy of determining the location of the object increases, because when using n relay towers that record a signal and m relay towers that do not register a signal, the object will be in the intersection zone of the indicated n towers - repeaters, from which areas of their suppression with the indicated m towers - repeaters are excluded. It is also possible to determine the speed of movement of an object using the determination of the time it moved from one zone to another zone, since the geometric dimensions of the zones and, therefore, the common parts of the zones are previously known. In the case of using towers - GSM relays of communication of various operators, roaming services can be used.

Also, to obtain the indicated technical result, it is proposed to use a system for determining the location of a moving object, characterized by the presence of a device containing a microprocessor connected to a power supply unit, as well as a transceiver unit whose output is connected to an antenna and the input to a microprocessor, and the specified microprocessor is made with the ability to periodically generate a command to transmit the specified part of the transmitting unit to the specified part of the receiving unit uniquely identifiable and identifying the device of the call signal of at least one tower-repeater connected via a radio channel from at least one base station of the operator and at least one personal computer connected via the INTERNET network to the specified base station of the operator. As a power supply, it is desirable to have a tool that provides recharging the battery (from solar panels, thermocouples, etc.). A device for generating and receiving a radio signal, in a preferred embodiment, is a means configured to create a self-calling zone around itself, which is a closed call signal from the device itself. The purpose of sending this signal is to leave a mark of your presence at least in the nearest repeater, which will then be transmitted to the operator’s base station, where it will be marked in the operator’s database (CDR - Call Data Record). In a preferred embodiment, the pickup signal should be fixed by the maximum possible number of repeaters, which will increase the accuracy of determining the location of the object.

A call to itself is handled by the operator’s equipment in the same way as a regular “correct” address call. But since in a telephone network such a self-call is logically meaningless, there is no connection and, therefore, such a call does not load the network and is not charged by the operator.

Using similar services, you can easily track all the movements of an object in the coverage area of a given cellular network according to the tag calls left by it in the CRD database, using a computer with Internet access.

Technically, the means of self-dialing is a simplified to the necessary “minimum” scheme of a standard GSM module (or similar device), of which all the possible functions are only those that allow it to send a call in a standard way (ring) to itself with a given frequency: a transmit-receive unit, antenna, microprocessor and battery.

Sim card data is recorded (flashed) in the microprocessor, as is the software timer for the periodicity of the self-call. After turning on the power, the beacon autonomously sends signals to the pickup network after set periods of time.

There are no bulky items in the device, such as a display and keyboard / dialer. The number for self-dialing is registered in the microprocessor along with the data of the SIM card. Therefore, the device can be completely placed in a compact microcircuit (“on a chip”) and then built into a monitoring (geomonitoring) object, or made into a portable wrist / pocket module for monitoring people and animals.

In the future, the essence of the proposed technical solution will be disclosed using examples of implementation.

To determine the migration paths of gazelles across the steppes, 5 young individuals were captured using a soporific shooting. In a sleepy state, they wore devices using leather ties that contained transceivers connected to an antenna and to a microprocessor capable of generating a control signal for a transceiver that provided a self-ringing signal with a frequency of 30 minutes. In this case, the transceiver and the microprocessor are connected to a power receiver containing a solar battery. The generated self-dialing signals from each device were received from one to six towers - repeaters, transmitting the signal to the operator’s base station and broadcasting the specified signal through the INTERNET network to the work customer - the agricultural department. The received signals characterizing the location of the animal were superimposed on a map with the determination of the zone of movement of animals. With minimal expenses for creating devices for transmitting self-calling signals, the migration routes of gazelles were determined, which allowed minimizing the loss of agricultural products by removing crops from the migration zone.

A group of tourists who embarked on a route through a sparsely populated area had one device for generating a pick-up signal, the microprocessor of which provided a pick-up signal with an interval of 1 hour. Throughout the route, the tourist club on the Internet received information about the whereabouts of the tourist group.

The application of the proposed system differs from the existing similar systems in GSM networks by the absence of payment for traffic. Existing systems operate mainly through tags via SMS messages, which, with a high frequency of sending tags, necessitates the payment of significant amounts as payment for outgoing SMS messages.

In addition, the proposed system can also work for free not only in the "native" network, but also through roaming, which makes it at the current level of development in the world of GSM networks and roaming between them a truly universal means of cheap geomonitoring of objects.

For the proposed system to work, there is no need to make a special monitoring site, as in his work he uses the services of mobile operators available on the market. There is also no need to create additional repeaters and operator systems, since the existing systems were used to implement the invention.

The proposed system for monitoring the movement of objects can be widely used in various areas of modern life: from monitoring parents for children to monitoring transport and cargo, up to monitoring the migration of wild animals or monitoring prisoners in prison.
