    • ByCH. RAJUO8Q61A0514
    • Introduction Automatic vehicle location (AVL) is a computer –based vehicle tracking system The actual real –time position of each vehicle is determined and relayed to a control center AVL systems include: computer -aided dispatch software, mobile data terminals, emergency alarms, and digital communications
    • About GPS: The GPS was specifically engineered so that at least four of the 24 satellites would be positioned on the horizon at all times. GPS Satellite
    • What is AVL technology? AVL systems use satellite and land communications to display each vehicles  location  status  heading  speed on the computers screen.
    • Navigation Technologies Four Navigation Technologies. They are 1. Global Positioning System 2. Dead-Reckoning System 3. Signpost/Odometer Systems 4. Radio Navigation/Location
    • TRACKING SYSTEMS There are two types of tracking systems  PASSIVE TRACKING  REAL TIME TRACKING
    • PASSIVE TRACKING: It refers to stand-alone GPS Receivers, which stores data for further process Passive Tracking systems are limited to vehicle tracking only It stores the location, time, velocity and heading data
    • REAL TIME TRACKING: It is based on mobile stand-alone terminals which combine GPS and GSM to transmit their position GPS Receiver
    • WORKING OF A GPS BASED AVL:It contains the following GPS SATELLITES RADIO SYSTEM COMMUNICATION CENTER DISPATCH SECTION CUSTOMER ASSISTANCE UNIT
    • WORKING OF SIGNPOST BASED AVL:It contains the following Optical scanners Magnetic strips Beam emission Short-range radio
    • SIGNPOST BASED AVL:
    • GROUND BASED RADIO AVL:.The system can operate with one or moreantennas that broadcast a signal
    • DEAD-RECKONING:
    • AVL Benefits:
    • Uses Of AVL Vehicle location display in real-time. Recording of arrival and departure times (proof of delivery etc). Monitoring of driving practices (speed). Alerts if vehicle leaves or enters a defined area
    • Applications Of AVL In Military Geo-Caching Track Anything In Cargo In cargo
    • Conclusion By using GPS we track the location of the vehicle It is a cost effective and efficient technique It gives protection to the vehicles and also the accident alerts
