AUTOMATIC VEHICLE LOCATOR
ByShubham GOELECE-III yearxyz
IntroductionAutomatic 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.
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 SYSTEMSThere are two types of tracking systems
PASSIVE TRACKING
REAL TIME TRACKING
WORKING OF A GPS BASED AVL:
GPS SATELLITES
RADIO SYSTEMS

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 AVLVehicle 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 AVLIn Military
Track Anything
In Cargo
In cargo
ConclusionBy 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
