Vehicle Tracking System - GPS :
A vehicle tracking system is an electronic
device installed in a vehicle to enable the owner or a third party to track the vehicle's location.
Most modern vehicle tracking systems use Global Positioning System (GPS) modules for
accurate location of the vehicle. Many systems also combine a communications component
such as cellular or satellite transmitters to communicate the vehicle’s location to a remote
user. Vehicle information can be viewed on electronic maps via the Internet or specialized
software. Current vehicle tracking systems have their roots in the shipping industry.Corporations with large fleets of vehicles required some sort of system to determine where
each vehicle was at any given time. Vehicle tracking systems can now also be found in
consumers vehicles as a theft prevention and retrieval device. Police can follow the signal
emitted by the tracking system to locate a stolen vehicle. Many vehicle tracking systems are
now using or a form of automatic vehicle location (AVL) to allow for easy location of the
vehicle. The GPS satellite system was built and is maintained by government and is available
at no cost to civilians. This makes this technology very inexpensive. Other AVL systems do not
require the antenna to be in direct line of sight with the sky. Terrestrial based systems such as
LORAN and LoJack tracking units use radio frequency (RF) transmitters which will transmit
through walls, garages, or buildings. Many police cruisers around the world have a form of
AVL tracking as standard equipment in their vehicles. Some vehicle tracking systems charge
the user a monthly subscription for a bundle that includes mapping software, hardware,
installation, and tracking service. Other companies offer units that are paid for upon
installation and will continue to work for the life of the vehicle. The decision to adopt an active
technology based on RF (e.g. LORAN), satellite or public carrier (e.g., CDMA) is driven by the
quantity of information, the frequency of updates, and the physical environment of the device.
For example a fleet manager may want 5 minute updates, telling whether a vehicle is on or off,
or may want 30 second updates tracking engine vitals, brake status, container status, vehicle
speed and direction and so on. |
