Introduction to GPS: How the Global Positioning System (GPS) Works and Its Key Components
I. Introduction to GPS
How does the Global Positioning System (GPS) work? Describe the key components of the system.
GPS, or the Global Positioning System, is a satellite-based navigation system that provides location and timing information to users around the world. Developed by the United States Department of Defense, GPS has become an integral part of modern society, with applications ranging from navigation and tracking to surveying and timing synchronization. In this article, we will delve into the key components of the GPS system and explore how it works.
II. Key Components of GPS
Satellites: Backbone of the GPS system
At the heart of the GPS system is a constellation of satellites orbiting the Earth. These satellites, known as Navstar satellites, are carefully positioned in precise orbits to ensure maximum coverage and accuracy. Currently, there are over 30 GPS satellites in orbit, with additional satellites serving as backups.
