The utility model relates to the field of navigation, and in particular to systems for determining the location of moving objects (vehicles) by signals from space navigation systems and their monitoring in order to control and track their movement using Inmarsat D + / GPRS communication channels. As the areas of application of the satellite telematics complex, there may be areas for dispatching public or special vehicles, security systems for private vehicles, search systems for stolen cars, etc.

The prior art system for monitoring, information services and protecting vehicles from unauthorized exposure (see patent of the Russian Federation for the invention RU No. 2155684, publ. 05.04.2000), containing a telephone communication network and data transmission connected to a paging communication network containing operator data transmission unit and subscriber receivers installed on vehicles, configured to activate immobilizers and launch beacon-type transmitters when sensors are not activated authorized impact on the object or when receiving blocking and beacon codes on a paging communication network, respectively. Also, stationary transceivers geographically distributed on the road network, configured to receive alarms from beacon-type transmitters and with the ability to transmit messages to at least one of the base stations associated with the information center. The information center contains serially connected reception unit and primary processing unit, the outputs of which are connected respectively to the registration unit and to the display unit, while stationary transceivers are capable of direction finding beacon transmitters and measure the power of signals received from them, and the information center contains a reception unit and processing messages from external sources, a block for transmitting information messages, a secondary processing unit connected to the outputs of the primary processing unit The operation of the registration unit, the display unit and the unit for receiving and processing messages from external sources and made with the possibility of determining the coordinates of vehicles from the aggregate data on the location of stationary transceivers that received alarms from beacon type transmitters, as well as with the ability to determine and account for the number of transmitter starts beacon type for financial settlements with the owner of the vehicle. 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.

This drawback is eliminated in systems and complexes using combined reception of signals from satellite radio navigation systems: American - GPS and Russian - GLONASS.

The prior art security system, control and navigation for cars (see US patent for invention US No. 5504482, publ. 02.04.1996), containing a storage device for storing roadmaps in digital form, a device for entering a destination, a device for forming digital signals of the vehicle’s speed and acceleration for indicating an emergency situation and an antenna for receiving signals from the satellite radio navigation system GPS and signals carrying information about the traffic stream and transmitting alarm signals. Received signals are converted to digital form. The processing device determines the current location of the car based on GPS signals and signals carrying speed and acceleration information, determines the first route between the current location and destination, and the second route at a high traffic density on the first route, transmits alarms encoded based on the current location if the acceleration of the car is outside the specified limits, and controls the car by electronic means.

The operation of this system is limited to the navigation of a mobile object, while the system does not allow for precise determination of coordinates, monitoring the health of the system’s hardware, collecting and storing information about the consumer’s travel route (logging events).

The prior art system for determining the location of moving objects (see the patent of the Russian Federation for utility model RU No. 63094, publ. 12/27/2006). The system contains a GSM modem, a GSM antenna, a SIM card from a mobile operator, a GPS receiver, a GPS antenna, a non-volatile memory controller, a controller programming port, a power supply, an integrated accelerometer, a motion detector, an off accelerometer power supply voltage regulator that can be turned off GPS receiver power supply voltage stabilizer, GSM-modem switch-off power supply voltage stabilizer, photosensitive element and LED status indicator and chemical current source. In this case, the first, second and third outputs of the controller are connected to the control inputs of the voltage stabilizer of the accelerometer, the voltage stabilizer of the GPS receiver and the voltage stabilizer of the GSM modem, respectively. The fourth controller output is connected to the module status indicator. A chemical current source is connected to the controller and to the inputs of all three voltage stabilizers. The output of the accelerometer supply voltage stabilizer is connected to an integrated accelerometer, the first and second information outputs of which are connected to the first and second inputs of the motion detector. The detector output is connected to the first input of the controller. The output of the power supply voltage stabilizer of the GPS receiver is connected to the GPS receiver, the serial port of which is connected to the first serial port of the controller. The output of the voltage stabilizer of the GSM modem is connected to the GSM modem, the serial port of which is connected to the second serial port of the controller. A GPS antenna is connected to the radio frequency input of the GPS receiver, and a GSM antenna is connected to the GSM modem. The SIM card is connected to the second serial port of the GSM modem. A photosensitive element is connected to the second input of the controller.

The disadvantages of the known system are:

- the lack of the possibility of periodic self-testing of navigation equipment installed on a moving object, obtaining reliable information about the health of the device with recording test results in the device event log.

- the lack of the ability for the user to conduct remote technical diagnostics of navigation equipment installed on a moving object using control commands;

- the dependence of navigation equipment installed on a moving object from the presence of voltage on-board network of the vehicle.

The technical result of the utility model is to increase the accuracy of navigation and increase the speed of response processes and interaction.

At the same time, the technical result in terms of improving navigation accuracy is achieved through the use of a two-system navigation receiver GLONASS / GPS and additional communication channels Inmarsat D + / GPRS ”. When using the GLONASS / GPS navigation receiver as part of the satellite telematics terminal, it becomes possible to determine the location where this is not possible if only one of the systems is used. In the event that communication with the telematics server via the GSM channel - the main channel could not be established, communication is established via the backup Inmarsat / D + communication channel, which increases the level of vehicle monitoring security. In the absence of communication via the backup Inmarsat / D + communication channel, the navigation parameters received from the GLONASS / GPS receiver are accumulated in the internal non-volatile FLASH memory. When establishing a connection with the telematics server, the transfer of accumulated navigation parameters about the movement of the moving object and the information of the triggered sensors of the moving object to the telematics server begins. Communication with the telematics server is carried out using the TCP / IP protocol, which provides greater reliability, since this protocol checks for errors and exchanges confirming messages. Data is sent in packets (TCP segments), which consist of TCP headers and data. TCP is a “reliable” protocol because it uses checksums to verify data integrity and send acknowledgments to ensure that the transmitted data is received without distortion.

The technical result "improving the responsiveness and interaction processes" is achieved through the use of CyberFleet and CyberWeb software, which is intended for monitoring and control in real time and functioning on the Internet in order to monitor moving objects.

The technical result of the claimed utility model is achieved by a combination of essential features, namely: GLONASS / GPS satellite telematics complex using Inmarsat D + / GPRS communication channels contains: satellite telematics terminal, including: GLONASS / GPS antenna, flash-memory, three-axis mechanical accelerometer, GLONASS / GPS navigation receiver, console port, redundant power supply, external power supply module, control microcontroller, satellite telematics term power supply control module ala, sensor, GSM modem to an antenna module for connecting interface devices, LED indicators, and satellite modem Inmarsat D + to the antenna, a data collecting server, a means of ensuring GPRS-exchange telematics server; PC of the dispatch center, while the GLONASS / GPS antenna receives signals from the spacecraft of the GLONASS / GPS navigation systems, the output of the GLONASS / GPS antenna is connected to the input of the GLONASS / GPS navigation receiver, the input-output of which is connected to the second input-output of the control microcontroller, the input - the flash memory output is connected to the first input-output of the control microcontroller, the input-output of the console port is connected to the third input-output of the control microcontroller, the output of a three-axis mechanical accelerometer is connected to the input ohm of the control microcontroller, the output of the thermal sensor is connected to the second input of the power control module of the satellite telematics terminal, the first input of which is connected to the output of the external power supply module and the backup power source, the output of the control microcontroller is connected to LED indicators, the fifth input-output of the control microcontroller is connected to the input-output a module for connecting interface devices, the sixth input-output of the control microcontroller is connected to the input-output of the joint venture Inmarsat D + modem with antenna, the seventh input-output of the control microcontroller is connected to the input-output of the GSM modem with the antenna, the output of the power module of the satellite telematics terminal is connected to all devices included in the satellite telematics terminal, the telematics server is connected via the Internet to the collection server data, from the PC of the control room and through the means of providing GPRS - exchange with a GSM modem with an antenna, the Inmarsat D + satellite modem with an antenna over the communication channels is interconnected via Inmarsat D system spacecraft and ground-based interface with the data collection server.

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 (SPS) 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), using the asynchronous serial UART (Universal Asynchronous Receiver / Transmitter), the navigation parameters are input to the control microcontroller (10) and then:

- through a GSM modem with an antenna (13) or a satellite modem Inmarsat D + with an antenna (16) to a telematics server (22);

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

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 (13), the Inmarsat D + satellite modem is turned on and initialized with the antenna (16), and it is 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 TSRLR protocol stack integrated into a GSM modem with an antenna (13) can significantly simplify the exchange of information carried out by a GSM modem with an antenna (13) over the Internet.

Communication with the telematic server (22) is carried out using the TSRLR 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 communication with the telematics server (22) via GSM and Inmarsat D + channels could not be established, the navigation parameters received from the GLONASS / GPS navigation receiver (6) are accumulated in the internal flash memory (4). 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.
