What is GPS

The Global Positioning System (GPS) is a space-based satellite navigation system that provides location and time information in all weather, anywhere on or near the Earth, where there is an unobstructed line of sight to four or more GPS satellites. It is maintained by the USA government and is freely accessible to anyone with a GPS reciever.

Uses of GPS

Positives and Negatives GPS.

Positive effects: Fewer plane crashes as GPS makes it easier for ATCs to tell where they are.
Several lives have been saved by GPS used in search and rescue operations.
GPS gave us geocaching (I view that as a pro, some others would say it's a con).
Navigating unfamiliar roads is much easier with GPS than with a traditional map.

Negative effects: Privacy concerns (there's a rumor that there's a way to pinpoint your location via a GPS enabled phone)
Dependence (People are forgetting how to use a normal map as more and more get used to GPS).

Apps that use gps.

AmaZe is a free turn-by-turn voice GPS app for the iPhone. You can view in 2D or 3D, and it offers many of the features of expensive GPS apps!

The graphics are decent, and the voice part is really helpful when you are driving.

Even though AmAze pops up a screen to buy the full version, there really is no need to do it. Simply tap on “keyword” or “local search” and you will get what you request
