A method switching a car GPS-module includes issuing command by a microcontroller to the GPS-module. With the help of an accelerometer the signal is fed to the system microcontroller, where it is processed and a signal for switching the GPS-module is shaped, with which is received a signal of the satellites of a navigation system and the information about the location of the vehicle is transmitted to the microcontroller, from which the information is transmitted to the GSM-module, with which through the GSM-antenna is performed the communication over radio frequency channel with the nearest base GSM-station of GSM-network. After that, from the GSM-station using batch communication service over GPRS- channels the information about the state of the system and data with the coordinates of the location of the vehicle is transmitted to the user’s mobile phone. |
