GPS Intro

What is GPS? 

The Global Positioning System (GPS) is a space-based satellite navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites.

Facts About GPS

•There are always at least 24 active GPS satellites circling Earth, although today there are more than 30, including a couple of spares. Their orbits are spread out so that no matter where on Earth you are, you will have at least six of them in your line of sight.

•Each GPS satellite goes around the world once every 12 hours. The satellites travel 12,500 miles (20,000 km) above us at roughly 7,000 miles per hour (11,000 km per hour). They have small boosters so they can adjust their path when needed.
