STEVAL-IEG001V2 2/12 docid026581 rev 1 description the STEVAL-IEG001V2 implements a smart vehicle tracking system reference design based on gps/gsm/gprs. the system is built around the cortex-m3 stm32f20x microcontroller series. today, tracking and navigation systems for vehicles are extensively used all over the world by public transportation units, fleet owners as well as by individuals, and are an essential component of vehicle telematics systems. the system consists of a vehicle unit (installed inside the vehicle) and remote web server application where the vehicle status and movement data can be viewed in an intuitive way on the map. the vehicle unit is built around cortex-m3 stm32 microcontroller, telit gps (sl869) module and sagem gsm/gprs module. the vehicle unit gathers gps information such as location coordinates, time, date, speed, in-journey distance traveled and satellites fixed and sends the data over gprs to the web server application. this web application displays the current location and status information of the vehicle in openstreetmaps. the same information is displayed locally on the graphical lcd display. this unit features the following mems sensors: lis331dlh 3-axis accelerometer and yaw/pitch/roll gyroscope l3gd20. this unit also serves as theft a detection unit and senses car lift using mems. in case of vehicle crash (detected using mems), the vehicle status and location parameters are logged within the microsd card and the same information is sent to the admin by text message, thereby implementing black box functionality.
