Answer 1

maybe this might help you better:The GPS (Global Positioning System) is a "constellation" of approximately 30 well-spaced satellites that orbit the Earth and make it possible for people with ground receivers to pinpoint their geographic location. The location accuracy is anywhere from 100 to 10 meters for most equipment.

Answer 2

Hello! The GPS does not study weather patterns or take photographs with planes or balloons. Therefore, B and C are eliminated. The GPS is a tool where it can point out where you are at and how far you are from a particular place getting satellites from above Earth. A is the only one that summarizes this. The answer is A.
