What My Satellite GPS Can Do That Your Road Atlas Can't
Television is not the only "cool" thing using satellites these days. For
anyone who likes to travel or wander, the GPS satellite navigation
systems that have been on the market for a few years are handy
on-the-road companions. Some automotive manufacturers offer GPS in select
car models however GPS can also be purchased after market and can be
operated outside of the car as well. Satellite GPS navigates through
signals received from the myriad of satellites orbiting earth and is
extremely accurate using the maps that are loaded into its memory.
So what does a satellite GPS device offer that a road atlas doesn't? GPS
satellite systems provide directions while traveling, generally through
voice instructions which allow the person to keep their eyes on the road.
No more pulling off to the side of the road to study a map, struggling to
read illegible print, or trying to find just the right spot with only a
dome light for illumination.
Satellite GPS devices are also "smart" as many can also provide updates
on weather and traffic information and then assist in mapping an
alternate route when barriers exist in the pre-planned route. This
flexibility and problem solving make it an invaluable tool when traveling
in an unfamiliar area.
Satellite GPS devices are also great to use when hiking, camping, cross
country skiing, and participating in similar outdoor activities. Their
small size and light weight make them a great tool outside of the car and
are often recommended by outdoor enthusiasts and organizations for safety
purposes.
Most satellite GPS devices sold in the US contain maps and points of
interest such as airports, hospitals, and so forth to the tune of over
one million locations. However, these devices aren't limited to the
boundaries of the US obviously. For those who wish to use the device when
traveling outside the country, many devices have flash cards which can be
used to download the appropriate maps corresponding with their
destination making satellite GPS a great travel companion.
For many potential users an important consideration is ease of use. Many
satellite GPS devices, such as the portable Sony Nav-U, are ready to use
right out of the box. It has maps and over 1.6 million points of interest
loaded into its memory. It offers a full color 3.5" touch screen display
and 2-way speaker system. Cost of an average satellite GPS device is in
the range of $400 to $600 dollars but given years of good service and
flexibility of use it would seem an excellent investment.
In the world of navigation or route finding, it seems that satellite GPS
devices will eventually put basic road maps and compasses into the same
realm as typewriters and carbon paper.
