Vehicle tracking and accident alert system

Abstract

Initially the GPS continuously takes the data from the satellite and stores the latitude and longitude positions in microcontroller's buffer. If we want to know the path of vehicle .we need to send a message to GSM which gets activated by receiving our message. If system detects the accident occurred to the car even then it is activated .At the same instant the GPS gets deactivated with the help of relay .As soon as the GSM gets activated it takes the last received latitude and longitude positions from the buffer and sends a message to the particular number which is executed in the program. After the message has been sent to the user the GSM gets deactivated and GPS gets activated. This is cyclic process.
