automatic vehicle location

  1. 1. ByCH. RAJUO8Q61A0514
  2. 2. 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
  3. 3. 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
  4. 4. What is AVL technology? AVL systems use satellite and land communications to display each vehicles  location  status  heading  speed on the computers screen.
  5. 5. Navigation Technologies Four Navigation Technologies. They are 1. Global Positioning System 2. Dead-Reckoning System 3. Signpost/Odometer Systems 4. Radio Navigation/Location
  6. 6. TRACKING SYSTEMS There are two types of tracking systems  PASSIVE TRACKING  REAL TIME TRACKING
  7. 7. 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
  8. 8. REAL TIME TRACKING: It is based on mobile stand-alone terminals which combine GPS and GSM to transmit their position GPS Receiver
  9. 9. WORKING OF A GPS BASED AVL:It contains the following GPS SATELLITES RADIO SYSTEM COMMUNICATION CENTER DISPATCH SECTION CUSTOMER ASSISTANCE UNIT
  10. 10. WORKING OF SIGNPOST BASED AVL:It contains the following Optical scanners Magnetic strips Beam emission Short-range radio
  11. 11. SIGNPOST BASED AVL:
  12. 12. GROUND BASED RADIO AVL:.The system can operate with one or moreantennas that broadcast a signal
  13. 13. DEAD-RECKONING:
  14. 14. AVL Benefits:
  15. 15. 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
  16. 16. Applications Of AVL In Military Geo-Caching Track Anything In Cargo In cargo
  17. 17. 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
