摘要： The invention relates to road traffic safety systems. A microprocessor (8) transmits navigational information about the location of a vehicle via the input/output port of a standard UART interface (10) to a GSM/GPRS modem (15) which authenticates a tracking tachograph in the GSM network with the aid of a SIM card (12) and then transmits the information obtained to a control center. Information from a GLONASS/GPS/GALILEO satellite navigation receiver (14) is sent using a standard NMEA protocol to the microprocessor (8), where it is converted, and the navigational component containing information about ground speed, latitude and longitude is subsequently transmitted to the control center. At the same time, the tracking tachograph time is synchronized with the UTC time used in the GLONASS/GPS/GALILEO satellite navigation system. The microprocessor (8) also receives information from an accelerometer (4), which supplements the information from the GLONASS/GPS/GALILEO satellite navigation receiver. The technical result is: an increase in the operational accuracy of the tracking tachograph as a result of synchronization with the UTC time used in the GLONASS/GPS/GALILEO satellite navigation system; a reduction, at no additional expense, in the labor intensiveness of installing and calibrating the tracking tachograph; a significant reduction in the cost of the tracking tachograph as a result of the exclusion of an encrypted sensor and encryption software; and also an increase in usability as a result of the ability to function in the GSM global system for mobile communications.
