Types Of GPS Devices
Author: Michelle Bery


The Global Positioning System – or GPS – has transformed how
the world finds its way. It's no secret that the popularity of
GPS has made it a standard feature in many a car. But in truth
there are quite a number of GPS devices that are used in today's
modern society. What began as a government experiment and then a
standard device used by the military, is now more popular than
ever in civilian society.

When Russia launched Sputnik in the late 1950's we had our
first glimpse into the role that satellites would play in our
future. Those who were monitoring Sputnik found that they were
able to pinpoint its location based on the radio waves it
provided. The seeds of GPS were born.

In the 1960s the U.S. Navy began experimenting with the
technology, using the positioning of six satellites to help
missile-carrying Navy submarines pinpoint their location. But
the Global Positioning System that we know today was designed
and implemented by the United States Department of Defense; the
first operational satellite was launched in 1978 and by the mid
1990s there were 24 satellites – all of which are still in
operation today.

The byproduct of this new technology has been GPS devices,
designed to harness the power of satellite navigation to offer
the highest level of convenience. It seems as though every year
more GPS devices hit the shelves and in so doing they become
part of what's expected in society. The types of GPS devices are
varied and your choice to use them depends largely on your
frequency of need.

One of the more popular GPS devices is GPS mapping that allows
you to visit any number of websites and enter any address in the
world. If satellites have access to this area, you are
immediately given a satellite picture showing the precise
location you requested. For mapping trips, these GPS devices can
take information downloaded from your computer and put it to use
in your car, giving you detailed directions for the most
expedient trip.

Another one of the more popular GPS devices is a GPS
navigational unit. These units can either be mounted in your car
or come in a portable system that you can transfer from vehicle
to vehicle. Once a destination is entered into the GPS
navigational system, it can literally walk you through your trip
telling you where to turn and the time and distance relative to
each portion of the drive. Some navigational units offer a
feature whereby you can find restaurants, shopping, hospitals,
and accommodations regardless of where you are; this can be
incredibly useful when hunting services in a town with which you
are unfamiliar.

GPS tracking, another of the GPS devices, allows you to track
another person or thing. Many parents use GPS tracking in the
cars of their teenage drivers. Others use this system to help
protect precious items that are in danger of being stolen.

No matter which of the GPS devices you choose, you will no
doubt find GPS to be an essential part of your life before long.
