AUTOMATIC VEHICLE LOCATOR
Introduction :
Automatic vehicle location (AVL) is a computer -based vehicle tracking system by using the satellite and land communication.
This system use GPS technology in tracking vehicles and protect the precious goods
This system send the information regarding actual location, heading and status of vehicle is determined and relayed to control center
Technologies employed for AVL
GPS (global positioning system)
dead reckoning
Odometer system
Radio navigation

AVL system architecture
Working of a GPS based AV L:
1.GPS satellites:
GPS satellites calculate The information regarding the location of the transit vehicle is by TRILATERATION method.
The GPS unit in the vehicle absorbs the signals from GPS satellites And send those signals to the RADIO system.
2.Radio system:
The RADIO systems receive the vehicle GEO -LOCATION coordinates and transmits this radio signals to Communication center
3.Communication center:
The communication center receives the information from radio system. uses it to determine the location of transit vehicle and sends this to customer assistance unit through wire line or wireless networks.
4. Customer assistance unit:
This section use vehicle location map to help and provide traffic information for other road way driver.

TRACKING SYSTEMS
The AVL tracking system consists of a GPS receiver inside the vehicle
.
There are two types of tracking systems are there
1.Passive tracking system
2.Real time tracking system
1.Passive systems are refers to stand alone GPS receivers
Passive systems are typically limited to vehicle tracking only.
When a passive systems are installed in the vehicle the location, time status and heading of the vehicle data are usually transferred to their base station
Real time tracking systems:
Real time tracking systems are based on mobile
terminals which combine GPS and GSM technology to determinate and transmit their vehicles position.
In this two-way wireless communication page link connects the GPS unit with the control center at all times.
APPLICATIONS IN OTHER FIELDS:
In cargo
Child Tracking
1.IN CARGO :
A small GPS receiver inside the cargo can know exactly
where it is, how far it is from the destination, and where to
find even it if it is stolen.
Child Tracking:
Ëœchild tracking', giving the possibility for children to wear or carry some sort of GPS/GSM tracker. Such a device could provide valuable information if a child is abducted or lost.
Signals could be sent from the tracker to a central site when a Ëœpanic buttonâ„¢ was pressed by the child.
BENEFITS:
1. Vehicle location display in real-time.
2. Recording of arrival and departure times vehicles
3. to the know position of cargo where it is
4. Alerts if vehicle leaves or enters a defined area
5.Child Tracking
conclusion
If we are using this AVL technology we can protect our vehicles ,cargo sand child's.
we know about the vehicle actual location ,status and speed.
THANK YOU
