Global Positioning Systems (GPS) Essay Example

Global Positioning Systems (GPS) Essay GPS, or Global Positioning Systems, is a system of many satellites orbiting around the earth. The U.S at first developed this system of satellites for military advantages in the war, but was later released for civilian usage. GPS took the place of maps and became more effective than 813paper maps. Citizens now can obtain a GPS just by buying a new car or cell phone. Citizens can buy a mobile GPS, which allows you to take it anywhere. Traveling in the 21st century is safer and quicker for citizens that own a GPS. Global Positioning System provides citizens with positioning, navigation, and timing services. The system is made up of at least twenty-seven radio satellites owned by the U.S government. Three of those satellites are replacements for any satellite that becomes dysfunctional. These satellites fly in space and orbit the planet two times a day. The U.S built solar panels to allow them to power themselves while they orbit the earth. (Baehr) The solar panels also help direct the satellites orbit. As the satellites orbits the earth, they send out microwave signals to receivers on earth .Then receiver breaks down the signals to find a precise destination or location of more satellites to triangulate your exact location on earth. This operation is based on a simple mathematical principle called trilateration. Devices on Earth such as a receiver can access at least four satellites. (Baehr) Receivers on earth are very common in cell phones, cars, and navigational systems. The receiver picks up a microwave signal from the satellite and uses the data to calculate how far away the satellites are.( Baehr) The receiver, now having the data, does this again with 3 or more satellites. The receiver knows its exact, precise location and stores the information gathered from the satellites signals. Receivers not only track the exact location, but they can also compute velocity and time. Receivers can even compute a satellites microwave signal i We will write a custom essay sample on Global Positioning Systems (GPS) specifically for you for only $16.38 $13.9/page Order now We will write a custom essay sample on Global Positioning Systems (GPS) specifically for you FOR ONLY $16.38 $13.9/page Hire Writer We will write a custom essay sample on Global Positioning Systems (GPS) specifically for you FOR ONLY $16.38 $13.9/page Hire Writer
