Automotive GPS Helps Keeps You On Course
More than two dozen satellites orbiting Earth at about
12,660 miles are able to tell you where you are and which way to turn to get to
where you are going. That may be over-simplifying the process, but essentially that
is how automotive GPS works. Technically, it is the software in a GPS unit in
your vehicle that reads the information transmitted from the satellites, that
determines where you are located. Additionally, software storing pre-programmed
information concerning locations that merges with your location to give you
navigational directions to reach your destination.
Information from four or more satellites received at the
same time by the automotive GPS unit in your vehicle, determines your current
location. Most navigational units have the ability for the user to input
specific geographic locations to help the unit determine where on the globe
your car is located. Many vendors offer computer downloads for automotive GPS
systems of various locations to enable turn-by-turn directions to be given to a
set destination.
While most automotive GPS systems are accurate, pinpoint
accuracy is not possible due to some variables such as weather or other
conditions that may interfere with the signal getting through. An accuracy of
three to 10 feet is typical for most automotive GPS units.
Keep Tabs On Vehicle If Stolen
Depending on the service you have for your automotive GPS
unit, it is possible to locate your vehicle regardless of where it is located.
If stolen, a quick check on your computer or with your GPS service provider can
usually help locate the car. Many vehicles equipped with an automotive GPS
tracking device are eligible for discounts on their insurance premiums.
One of the advantages of an automotive GPS unit is when you
are traveling through new areas. Knowing where you are headed before you leave
you can download information into your automotive GPS system and then rely on
the unit’s navigation system to help you if you get lost. Simply enter the
location where you want to end and the system will show you how to get there.
While the information being sent from the satellites is
free, paid for through taxpayer money, processing information received through
units such as navigation systems and stolen car locator services, are typically
charged by a vendor. Usually a monthly fee is assessed the amount depending on
the services to which you subscribe.
