Introduction Automatic Vehicle Locator (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

What is AVL Technology? AVL systems use satellite and land communications to display each vehicle's  location  status  heading  speed on the computer's screen.

AVL System

Navigation Technologies There are four types of NAVIGATION TECHNOLOGIES:-  Global Positioning System  Dead-Reckoning System  Signpost Systems  Radio Navigation Systems

About GPS: The Global Positioning System (GPS) is a space-based satellite navigation system that provides location and time information in all weather, anywhere on or near the Earth, where there is an unobstructed line of sight to four or more GPS satellites.satellite navigationlocation GPS Satellite

MORE ABOUT GPS….. There are six different orbiting patterns that the GPS satellites follow, making a complete trip around the earth every 12 hours.

MORE ABOUT GPS…..  The best position for any GPS antenna is generally as high as possible with the best unrestricted view.  The information regarding the location of the transit vehicle is calculated by TRILATERATION method.

TRACKING SYSTEMS There are two types of tracking systems  PASSIVE TRACKING  REAL TIME TRACKING

WORKING OF A GPS BASED AVL:  GPS SATELLITES  RADIO SYSTEMS

Working continued ….  COMMUNICATION CENTER  DISPATCH SECTION  CUSTOMER ASSISTANCE UNIT

A GPS BASED AVL sYSTEM

MAPPING  Maps allow a tangible, understandable view of vehicles location and will also allow operators to apply local knowledge.

CURRENT LIMITATION OF EXISTING METHOD  User compulsory needs a computer to access lost vehicle information.  User cannot decode GPS coordinates by himself.

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 Track Anything In Cargo In cargo

Conclusion By using GPS we can 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
