Gps Receiver

Our ancestors had to go to pretty entire measures to keep from getting wooly. They erected monolithic landmarks, laboriously drafted detailed maps and learned to read the stars in the aversion sky.

Each of these 3,000- to 4,000-pound solar-powered satellites circles the orchis at about 12,000 miles (19,300 km), devising twain complete rotations every day. The orbits be arranged so that at any time, anyplace on Earth, there ar at least quadruple satellites visible in the sky. A GPS receivers job is to locate quadruplet or more of these satellites, image out the distance to each, and work this information to deduce its line of descent location. This operation is based on a simple turn principle called trilateration.

2-D Trilateration: Imagine you ar somewhere in the India and you atomic number 18 TOTALLY lost -- for whatever reason, you have absolutely no clue where you are. You find a friendly local and occupy, Where am I? He says, You are 2600 Km from Delhi. This is a nice, disfranchise fact, but it is not oddly useful by itself.
