Final answer:
The Global Positioning System (GPS) is a navigation system that uses a network of satellites to provide precise location information, within about 50 feet, to GPS receivers on Earth.
Step-by-step explanation:
The navigation system consisting of earth-based receivers that accept and analyze signals sent by satellites is known as the Global Positioning System (GPS). GPS technology utilizes a constellation of at least 24 satellites orbiting the Earth, with at least 4 satellites visible from any location on the planet at any given time. These satellites are equipped with precise atomic clocks, and the system calculates your location by measuring the time it takes for the signals to reach your GPS receiver.
GPS is essential for creating accurate maps and determining precise locations on Earth. This system enables users to find their latitude and longitude to within at least 15 meters or about 50 feet. From transportation to personal mobile devices, GPS technology has been integrated into myriad applications vital for the movement of people, goods, and services around the globe.
