AUTOMATIC VEHICLE LOCATION
ByCH. RAJUO8Q61A0514
IntroductionAutomatic 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
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
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.
Navigation Technologies Four Navigation Technologies. They are
1. Global Positioning System
2. Dead-Reckoning System
3. Signpost/Odometer Systems
4. Radio Navigation/Location
TRACKING SYSTEMSThere are two types of tracking systems
PASSIVE TRACKING
REAL TIME TRACKING
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
REAL TIME TRACKING:It is based on mobile stand-alone terminals
which combine GPS and GSM to transmit their position
GPS Receiver
WORKING OF A GPS BASED AVL:
It contains the following
GPS SATELLITES
RADIO SYSTEM
COMMUNICATION CENTER
DISPATCH SECTION
CUSTOMER ASSISTANCE UNIT
WORKING OF SIGNPOST BASED AVL:
It contains the following
Optical scanners Magnetic strips
Short-range radio
Beam emission
SIGNPOST BASED AVL:
GROUND BASED RADIO AVL:
. The system can operate with one or more antennas that broadcast a signal
DEAD-RECKONING:
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 MilitaryGeo-CachingTrack AnythingIn Cargo
In cargo
ConclusionBy 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
