GPS stands for Global Positioning system which relies on the satellite for navigation instructions. It provides information such as location, time and weather in a specific area. Meanwhile, these maps provide data through images. It is capable in uploading routes, shortcuts and can also track other GPS units.
The GPS system comprises of 5 ground stations and 24 satellites called NAVSTAR. The ground stations make sure that the satellites are at their assigned orbits. The Department of Defense has placed 24 satellites in a certain orbit with an altitude of 10,900 miles. Each satellite orbits around the Earth in less than 12 hours. Each Satellite transmits their own unique type of signal and is stored separately in the GPS unit as signatures. The distance per satellite is measured by radio waves and how long it reaches the GPS unit. You will be able to view GPS maps through the captured images from the satellites.
