GPS Auto Navigation Systems
By: Cooper Miller
Over the past couple of years, the cost of installing a
GPS auto navigation system has fallen considerably, and
as an inevitable result of this, more and more people are
taking advantage of it in order to make it easier to find
out where they are going, plan their journeys, and keep
track of where they are.
Satellite navigation dates back a lot longer than many
people realize. The principles behind SatNav were first
tested back in 1967, but it took nearly 30 years before
the NavStar GPS System first began operation as a
military application in the mid 1990s. Civilian use of
GPS navigation was made available soon after the military
launch, but the initial costs of using the system were
very high, and required ongoing subscriptions to be paid.
The first people who took advantage of GPS were pilots,
and surveyors, who needed to be able to measure distances
with pinpoint accuracy. In the early days , an affordable
GPS auto navigation system was out of reach for the
average car owner.
Over time, the costs of GPS auto navigation system has
fallen considerably, and there are increasing numbers of
applications for them and the data that they provide in
our daily lives. Manufacturers such as Garmin and TomTom
have combined GPS signals Data with existing map
information and complex mathematical algorithms to create
systems that can be used for navigation on the roads and
highways.
These GPS auto navigation systems can be installed into
any car in a matter of minutes, and then be used to plan
journeys, and keep track of where you are to stop you
getting lost on the roads. By being combined with other
data, such as traffic news feeds, GPS auto navigation
systems can warn drivers about road congestion, and
provide alternative routes in real time to ensure that
no-one who has such a GPS needs get stuck in a queue
again.
There are a number of different styles of GPS auto
navigation systems available to suit the needs of the
individual, from basic models through to expensive and
highly accurate systems able to manage large amounts of
data and provide information to the users in order to
give feedback about where they have been.
The simplest kind of auto navigation GPS system is a
removable gadget that stores the map data internally, and
uses a satellite signal to pinpoint the position of the
unit. By combining the map data and the satellite signal,
routes can be planned, and the user can find their way,
while seeing a graphical representation of their route on
a small screen. These GPS auto navigation systems can be
either removable, or fixed into the car. Many new models
actually integrate the GPS into the dashboard, while non
fixed systems can either be mounted on the dash, or
attached to the windshield using a suction cup.
As well as dedicated auto GPS devices, it is also
possible to buy a large number of other gadgets with GPS
as a built in feature. Some GPS PDAs can have a GPS
module plugged in to them, and used in cars, and an
increasing number of cell phones have GPS as a standard
feature. On the whole, although these devices have GPS
built in, it is not of the same standard as a dedicated
system, and wile it may help you know where you are, it
will not provide such accurate data or be able to plan
routes on the go as well as one of the custom systems
from Garmin or Magellan.
At the top end of the list of auto navigation GPS
systems, there are a number of fantastic options
available. Many of the high end GPS auto navigation
systems include a range of features to make getting
around as simple and convenient as possible.
Aside from the standard information about maps and
positions, these GPS systems can also provide information
about local amenities such as gas stations, motels, and
even speed control cameras in certain countries. More
expensive GPS auto navigation systems come with the
ability to upload additional map systems so they can be
used in different countries, and through the use of local
radio services, provide comprehensive traffic information
to the driver wherever in the world he is.
Whether you want a simple auto navigation GPS system to
help you avoid the traffic problems in your home town, or
are a cross country driver who needs the long distance
planning flexibility for getting from a-to-b as
efficiently as possible, there is a GPS system available
that will suit your needs.
