What is “GPS”?
“GPS is the world’s first satellite navigation system. It was developed and is maintained by the U.S. Government’s Department of Defense. GPS consists of 3 key elements: satellites in space, monitoring stations on Earth and your GPS receiver. GPS has 24 active satellites that circle Earth in orbital paths, sending out radio signals from their position in high orbit. Each satellite’s signal covers a large area of the earth’s surface and they are orbiting so that your GPS receiver back on Earth is always getting signals from at least 4 satellites (the number you need to pinpoint your location) unless covered by obstacles on earthe surface. There are 5 monitoring stations: the master station in USA and four unmanned stations around the globe. Your GPS receiver picks up signals from GPS satellites to work out your location. Each satellite transmits low power radio signals. The signals travel by so-called ‘line of sight’. This means they pass through clouds, glass and plastic, but not usual
GPS (Global Positioning System) is a constellation of satellites orbiting the earth. A GPS receiver can determine it’s coordinates anywhere on the face of the earth as long as it has a clear view of the sky. Our software uses this coordinate information to show the location on a digital map and also to determine a driving route to a destination.
GPS (Global Positioning Systems) allow you to easily determine where you are, practically anywhere on the planet. A collection of 24 satellites orbit the Earth, allowing people with portable navigation devices, in-car navigation systems or specially equipped cell phones to pinpoint their geographic location on a map. GPS enabled navigation systems come pre-loaded with full color, easy-to-read maps that can help you find your way around. Points of interest are also often included, to help you find places like restaurants, gas stations, landmarks and more-wherever you are, or wherever you’re going.
