The block for transmitting information messages through the voice messenger is connected to a geographically distributed network of centers for operational response. At the same time, vehicle owners are equipped with transponder cards (TC), on which secret codes are written in certain fields: blocking, beacon and settlement, and the subscriber’s identification code is recorded in the digital memory of the TC. On each vehicle in the immobilizer control unit, a remote identification code reading unit with a TC and a manual unlocking code input unit are installed, connected to the corresponding inputs of the immobilizer control unit, as well as an indicator of the operation modes of the security sensors associated with its corresponding output.

The disadvantage of this system is the low accuracy of determining the coordinates of controlled moving objects, significantly limiting the scope of practical application of the system.

The principle of operation of the claimed satellite telematic complex is based on the principle of determining the location of a moving object using signals from GLONASS / GPS space navigation systems (GPS) and on the principle of monitoring a moving object using a telematics server using Inmarsat D + / GPRS communication channels.

When supplying voltage to the satellite telematics terminal (2), the signals emitted by the SSC are received by the GLONASS / GPS antenna (3). From the output of the GLONASS / GPS antenna (3), the amplified and filtered signal is fed to the input of the GLONASS / GPS navigation receiver (6), which receives, converts, processes the signals of navigation spacecraft (NSC) and outputs the results of solving the navigation problem - navigation parameters ( time, coordinates, ground speed vector) of a moving object. From the output of the GLONASS / GPS navigation receiver (6), the navigation parameters go to the input of the receiver module (10) and then:

- through a module for working with a GSM modem with an antenna (13) to the input of a GSM modem with an antenna (17) and then to a telematics server (22) or through a module for working with a satellite modem Inmarsat D + with an antenna (14) to the input of a satellite modem Inmarsat D + with antenna (18) and further to the telematics server (22);

- to flash-memory (4) (in the absence of communication with the telematic server (22));

- to the slot for a flash memory card (24) for recording on a flash memory card. The use of a three-axis mechanical accelerometer (5) integrated in the satellite telematics terminal (2) allows independent of the signals of the GLONASS / GPS navigation receiver (6) to determine the presence or absence of movement of the tracked object. Thus, due to this property of a three-axis mechanical accelerometer (5), in the case of prolonged immobility of the tracked object, the GLONASS / GPS navigation receiver (6) can be turned off to save energy. Subsequent activation of the GLONASS / GPS navigation receiver (6) will occur upon a signal from a three-axis mechanical accelerometer (5), which will appear when the moving object resumes movement.

Simultaneously with the operation of the GLONASS / GPS navigation receiver (6), when power is supplied to the satellite telematics terminal (2), the GSM modem with the antenna is turned on and initialized (17), the Inmarsat D + satellite modem is turned on and initialized with the antenna (18) and registered in GSM Networks or Inmarsat D + Networks.

Using GPRS technology allows for packet data transmission via GSM-communication and significantly reduces the cost of tracking a mobile object.

The TCP / IP protocol stack built into a GSM modem with an antenna (17) makes it possible to significantly simplify the exchange of information carried out by a GSM modem with an antenna (17) over the Internet.

Communication with the telematics server (22) is carried out using the TCP / IP protocol, which is supported by all modern networks, provides greater reliability (checking for errors and exchanging confirmation messages). Data in the protocol is sent in packets (TCP segments), which consist of TCP headers and TCP data.

Monitoring errors in the transmission of information in the protocol is achieved by using checksums to verify the integrity of the data and send receipts with information about the reception and transmission of data without violating their integrity.

Using a satellite channel operating in the Inmarsat D + standard as a backup communication channel allows packet data transmission in the event of a GSM connection failure.

If it was not possible to establish communication with the telematics server (22) via GSM and Inmarsat D + channels, the navigation parameters received from the GLONASS / GPS navigation receiver (6) are accumulated in the internal flash memory (4), as well as on the external flash card memory, if available, in the slot for connecting a flash memory card (24). When establishing communication with the telematics server (22), the transmission of accumulated navigation parameters about the movement of a moving object to the telematics server (22) begins. It should also be noted that data can be written to flash-memory (4) at the command of a user from the dispatch center (23) with established communication with the telematic server (22).

The transfer of navigation parameters about the movement of a moving object to a telematics server (22) can occur in one of the following modes:

- “on-line” mode - regular sending of navigation parameters about the movement of a moving object;

- “on-line” mode - sending navigation parameters and sensor parameters upon the completion of a certain event;

- automatic transmission of navigation parameters about the movement of a moving object from the flash memory of the "black box".

The choice of the transmission mode of the navigation parameters is set by the user by applying special control commands to the inputs of the satellite telematics terminal (2).

The navigation parameters of the monitored moving object transmitted to the telematics server (22) using GSM or satellite communication channels are used by the CyberFleet ^® / CyberWeb ^® cartographic software (software) to display the location of the monitored moving object on an electronic map (on the user's monitor screen). The display of the location of the monitored moving object on the electronic map can be either graphic or textual (the history of the movement of the moving object).

User control of a moving object can be carried out in two ways:

a) using a portable communicator connected to the Internet;

b) using a personal computer connected to the Internet.

Data from the telematic server (22) can be received and displayed in two ways:

a) through the CyberWeb® Web access service (when using a portable communicator);

b) through the special client software CyberFleet® (when using a personal computer).

CyberFleet® software provides a three-level level of protection and allows automatic updating of used programs using the Internet (21). The multilingual software interface allows the user to translate any word in the interface. Database backup and cleaning tools used in CyberFleet® software provide the user with a wide range of possibilities when working with the program.

The claimed satellite telematic complex provides accurate navigation and reliable operation through the use of a powerful computing core, a highly informative graphical interface and an expanded software help system, an integrated database of navigation data.

PC dispatch center (23) is configured to:

- monitoring the location of moving objects in real time;

- use of a multi-level cross-reference help system built into the interface;

- use of context-sensitive help in all interface windows;

- receiving and processing data from a telematic server.

- determination of coordinates and motion parameters (speed, direction of the velocity vector, distance traveled, etc.) from the signals of the GLONASS / GPS satellite navigation systems;

- monitoring various sensors and determining whether one or more sensors are triggered;

- the ability to connect additional external short-range radio devices (WiFi), digital cameras;

- exchange with the vehicle information bus (CAN) using special adapters;

- information exchange with a personal computer (PC) via the USB port;

- transfer of information about coordinates, motion parameters and triggered sensors to the telematics server of the vehicle monitoring system (SMTS) in automatic mode;

- receiving information from a telematics server to control digital outputs.

LED indicators (16) provide LED indication of the status of the satellite telematics terminal (2) and display the following:

- the presence of supply voltage;

- GLONASS / GPS receiver initialization mode;

- search mode for navigation satellites;

- satellites found, data from the GLONASS / GPS receiver reliable;

- initialization mode of the GSM modem;

- readiness of the GSM modem for work, check;

- GSM network search mode and registration in it;

- analysis of the presence of SMS commands in the memory of the SIM card;

- the GPRS connection is initialized and the PPP session is established with the operator’s GPRS gateway;

- installation of the PPP session is completed;

- the modem is in data transfer mode;

- The modem is in voice mode.

Thus, the use of the claimed satellite telematics complex GLONASS / GPS using Inmarsat D + / GPRS communication channels allows you to:

- determine the coordinates and motion parameters of the moving object from the signals of the GLONASS / GPS satellite navigation systems (with the GLONASS system taking precedence);

- display the location and movement routes of a moving object for any period of time on a detailed map of the city on the screen of a personal computer or portable communicator connected to the Internet;

- control the location of a moving object in a predetermined area or movement along a predetermined route.

The principle of operation of the module working with a GSM modem in the implementation of the intelligent roaming function is that before starting the data exchange between the satellite telematics terminal and the telematics server via a GSM network, the satellite telematics terminal will register in the GSM network. At the beginning of the registration process, a determination is made of the type of available GSM network ("home" or "roaming") - operation 43 in FIG. 3. If a home GSM network is available, then registration takes place in it - operation 45 in FIG. 3 and subsequent data exchange with the telematics server via the GSM channel. If it is established that among the available GSM networks there is no “home” GSM network, and all available GSM networks - “roaming” - to ensure optimal roaming, the following occurs:

1) the presence of the found GSM networks is checked in the available list of prohibited networks (no more than 10 networks (operators) recorded in the satellite telematics terminal memory) - operation 44 in FIG. 3; If all available (currently found) networks are in the forbidden list, the registration process stops and a second search for suitable networks begins - step 40 in FIG. 3.

2) after checking in the list of prohibited GSM networks, the presence of the found GSM networks in the existing list of allowed GSM networks is checked (no more than 10 networks (operators) recorded in the satellite telematics terminal memory) - operation 47 in FIG. 3;

3) after the list of available allowed GSM networks is formed, this list selects the GSM network that has the highest priority (lowest number on the list) - step 50 in figure 3 and, if such a network is found, the subscriber terminal is registered in a GSM network. If the found networks / network are not found in the list of prohibited networks and they are not found in the list of allowed networks, they receive the lowest priority for operation (virtual No. 11 in the list of allowed networks) - operation 48 in figure 3, after which the subscriber terminal is registered in this network, operation 45 in FIG. 3.

Depending on which GSM network in the “home” or “roaming” network the subscriber terminal was registered, two algorithms for further operation of the GSM module are possible.

The first - when registering in the "home" network, a mileage counter is started, which calculates the distance traveled by the subscriber terminal from the moment of registration in the "home" network. Upon reaching the set value of the distance traveled (the value is set approximately equal to the distance between neighboring base stations of the GSM network), a check is made to see if there is an automatic registration in the "roaming" network. If this happened, then the registration algorithm in the "roaming" network is launched, which was discussed above. If the subscriber terminal is still registered in the "home" network, then the mileage counter is reset and starts again.

The second - when registering in a "roaming" network, a mileage counter is started, which counts the distance traveled by the subscriber terminal since registration in the "roaming" network. Upon reaching the set value of the distance traveled (the value is set approximately equal to the distance between neighboring base stations of the GSM network), a check is made to see if there is an automatic registration in the "home" network. If this happens, then the algorithm for exchanging data with the telematic server is started when it is in the "home" network. If the subscriber terminal is still registered in the "roaming" network, then the mileage counter is reset and starts again.

When in a roaming network, there are two modes for exchanging data with a telematic server:

1) The mode of data transfer is “container” (by filling the container) - accumulated, transmitted, save further, etc. - the number of communications is not regulated.

2) The data transfer mode is “economical” (with communication several times a day) - each time a data volume less than or equal to the size of the container is transmitted, the rest of the data is stored in a “black box”. Under the condition of working in the Beeline network, the daily costs are equal: 28 rubles. multiply by the number of communication outputs.

In addition, interruption of operation in the "economical" mode for urgent events is provided.
