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

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
