AVL system with wireless access
Automatic Vehicle Locating (AVL System) is an advanced method of remote vehicle tracking and monitoring. Each vehicle is equipped with an AVL unit that receives signals from the GPS satellites. The GPS receiver determines its current location, speed and heading. Most popular Automatic Vehicle Location (AVL) system is based on GPS (Global Positioning System) and GSM (Global standard of mobile communication). Tracking data can be stored inside the AVL unit and can be as downloaded later via RS232 by connecting the unit to a PC. If the geographical position of all stops is not needed, the system can run without GPS receiver. All driven kilometres and times are calculated by the odometer interface and the internal real time clock.
AVL system based on GSM and GPS
GSM is the the most popular cellular communications network. There are 400 GSM operators in 170 countries. GSM offers the best value regarding price and performance compared to other cellular or wireless network systems.
