Got GPS?

Having a GPS these days is just super handy. If you don't already have one or aren't sure how it can really benefit you, then here is some information that might help you decide if you should get one.  GPS was developed by the US department of defense as early as 1973. It became fully operational in 1994. GPS devices calculate position based on the precise timing of signals sent and received by satellites in orbit. The early GPS units were quite primitive compared to todays and provided very limited function and a relatively large range of error.

            Today's GPS units are very sophisticated and much easier to use than the earlier models. They are also much more accurate and provide myriads of additional useful information. If you are getting ready to go on a trip, then all you need to do is enter the address or location you are planning to visit and the GPS will calculate the route. You can also set a variety of options in your trip planning. If you happen to be driving through a beautiful landscape then you might prefer to set the route to 'scenic'. You won't get there as fast but you will find lots of interesting and beautiful things along the way. You can also set the GPS to avoid things like toll roads, highways, and hazardous areas. Almost all GPS units today feature turn by turn directions with audible voice instruction.

            A GPS's other features though are well worth learning about. If you find yourself running low on fuel (we've all been there!) then you can easily find the nearest gas station and continue on your route. This feature is also great for finding food along the way or other points of interest that you might otherwise be unaware of. Some units also have weather and traffic alerts. The traffic alert is simply awesome. It can prevent you from being stuck in a jam due to accident, road construction or some other type of obstruction. The value of this kind of real time information cannot be overstated. Some units even go beyond this and provide speed warnings, maintenance alerts, or even have MP3 capabilities.

            Once you have arrived at your destination, the GPS's uses are far from over. Often times you won't know much about the area surrounding you, so all of the gas, food, and points of interest information the GPS provides is still extremely useful. Many GPS units even provide telephone numbers so you can call ahead to find out more about a place you are considering. It really can turn a relatively dull and uninspiring trip into a fun filled and memorable experience for everyone.

            If you think a GPS is out of your budget then you will be delighted to know that the cost of GPS ownership is very minimal these days. The units themselves can be picked up for around $100 to start and still come with many of the options mentioned above. Try to find a unit that offers lifetime traffic and map updates, included in the purchase price. The ease of use, low cost, and myriads of information at your fingertips make owning a GPS today a sheer pleasure and once you have made the decision to get one, you'll probably wonder how you ever lived without it.
