My grandpa loves Harry Potter, because this boy has a magical stick. And me, I love myself because in my pocket I have a ‘magical stick’ that I called GPS.
GPS (Global Positioning System) is my best friend. I don’t need spend money for him. GPS operates in any weather and temperature- from the snowy mountain to the tropical equatorial regions like Bali Island. Some of the reasons GPS is my best friend are:
Worldwide coverage: My GPS that I buy in Indonesia can be used in Texas, India, or Philippines - the same equipment for anywhere.
Accurate three-dimensional positioning: GPS provide horizontal and vertical positions accurate.
Accurate timing: I know not only where, but also when because GPS signals provide very accurate time.
24-hour availability: GPS is not ambulance, but satellite data is available continuously 24 hours a day. But best of all, GPS signal are free to all users. Hmm, it's nice to hear it? Maybe, this is a reason that GPS becoming the international standard for navigation. It's a powerful system, available to everyone, especially for you! In internet, you can find any free GPS software. The best place to find them is in http://www.free4map.com/Today, GPS receivers are fast becoming small enough and cheap enough to be carried. You can find GPS in cigarette-box size. You can put GPS in your pocket and go anywhere.
