Things you won't be told about Auto Navigation Systems
Auto navigation systems have come such a long way since
their inception. It's hard for many to see the product that
exists now and realize exactly how far these devices have come
since their origins in the U. S. Armed Forces. The thing to
keep in mind and remember is that they still have a long way to
go. These devices are far from infallible and still have some
serious faults that prohibit us from canning the compass and
maps all together.
One thing to keep in mind is that there are almost always
problems of some sort with electronic equipment. This is
especially true when it comes to equipment that is run by
software. If anyone doubts the validity of this statement,
check out a computer that is run by Windows? We often find
ourselves at the mercy of the limitations of the software we
are using. The same holds true when it comes to software driven
auto navigation systems and GPS devices. This fact alone makes
them a little unreliable. For those times when reliability
isn't at its best keep in mind that for the most part the
system works well. It's just difficult when the times you need
it to work well are the times when it is malfunctioning. The
good news is that the units themselves are often quite
resilient and even able to withstand the manhandling a typical
rough and tumble two year old can dish out.
It is also important to keep in mind that GPS technology
isn't meant to replace the use of maps or of common sense when
driving. You can only store so much information on a GPS device
and roads are constantly being built, changes, constructed,
improved, and moved. For that reason alone it is nearly
impossible to guarantee that any device will have 100% accurate
information at all times. You should however, choose a device
or auto navigation systems that allows frequent and simple
upgrades to the maps provided. Updating regularly and
immediately prior to any large trips will go a long way towards
saving some serious hair pulling while you travel.
Another thing to keep in mind with your auto navigation
device is that it isn't all that reliable whenever you don't
have a clear view of the sky. For that reason there may be
times when you aren't able to get a clear signal. Tunnels are a
great example of one of those times. It's not just about one
signal, the device must be able to lock onto three satellites
at the very least in order to be 'seen'. A fourth satellite is
usually required for verification of the data. This means that
in some situations where you have a clear view of the sky, you
may not be in a position where all four satellites have a clear
view of you and more importantly your device.
GPS and auto navigation systems are still a far cry better
than trying to read dusty old maps for most of us. Despite
that, it is always a good idea to go into a buying situation
with all the facts in hand rather than thinking you've
discovered the next best thing to sliced bread only to find out
that the crust is a little hard and crumbly at times. This
technology is wonderful and affords many benefits to those who
are willing and able to make use of it. It will never sacrifice
common sense or map reading skills however and that is
important to understand.
