One of the best apps on a phone is the GPS, and it is used to know your exact location and take you to your destination. Global Positioning System is known as GPS. This process allows GPS to determine your location with high precision. The American government currently owns this technology which was originally created by the U.S navy and is being operated by the Air force. This technology was first launched on February 22, 1978 and it has improved a lot since then.
GPS works by putting satellites up in space revolving around earth. The satellites receive and send signals to you phone. Three or more satellites will see the signal your phone sends and will know your general location, but then the others satellites will find your exact location. These are called receivers. The receivers receive signals from any phone, car, or computer, and they are as small as a pocket calculator. No matter what model your phone is, this processes works the same way to pinpoint your location. You might be located based on many different factors, typically with incredible accuracy. The program will use the most effective strategies to find you. Even though you might not use GPS everyday, it is still very important and useful.
