GPS System: Advantages & Disadvantages

Global Positioning System also known as GPS. The U.S. Department of Defense created GPS for the U.S. military, in order to allow them to navigate under any conditions, all over the world. The GPS systems which are available to the consumers today use the same satellite signals as the one used by the military.

There are many key advantages offered by the consumer GPS devices, however on the other hand there are few disadvantages that every one should be aware.


1. Easy Navigation System

Now you don’t need worry about deviating from your path while you are hiking or if you are lost in a strange town and don’t know the way out just relax because you have the GPS. The navigation system in a GPS device can provide you with turn-by-turn directions even if you are in a car as there are GPS devices available for cars as well and it could be a very useful feature in a strange town or place.

2. Nearby Area Search

There are some GPS systems that can allow you to search the area around you for nearby services like restaurants, hotels and gas stations. This feature is extermily useful in situations like if you are driving cross-country and suddenly realize that your car is braking down, you can always search for the m=nearby auto mechanics and select the one that is along your way. Your GPS system will show you exactly how to get there.

3. Navigation over Water

GPS devices can work perfectly for water navigation. In the past, boaters had to use a compass and a map in order to determine where exactly they are heading and with somewhat vague results as there were no landmarks in the large bodies of water. However, the arrival of GPS systems allowed them to find out their exact location on the map. Underwater hazards are always a problem; here GPS devices can allow boaters to steer around hidden dangers under water.


1. Potential Failures

You should always carry a backup directions and maps in case your GPS fails due to some reason. For example, if you are driving down a city street, the buildings may block the satellite signal, preventing you from receiving position updates. If you are hiking in the wilderness, your handheld GPS receiver’s battery may die, leaving you with no way to navigate. It’s always a good idea to bring a compass along while going for hiking.

2. Ambiguity

GPS signals are not always completely accurate. Hindrance like buildings and trees can avert the signal, causing your position on the GPS screen to be off by as much as 100 feet. Atmospheric conditions (such as geomagnetic storms caused by solar activity) may also affect GPS accuracy. For highway driving, this can cause you to miss a turn or exit.
